text: 2006 pacific hurricane season the 2006 pacific hurricane season was the most active since 2000 , which also produced 19 tropical storms or hurricanes . eighteen developed within the national hurricane center ( nhc ) area of warning responsibility , which is east of 140 ° w , and one storm formed between 140 ° w and the international date line , which is under the jurisdiction of the central pacific hurricane center ( cphc ) . of the 19 total storms , eleven became hurricanes , of which six attained major hurricane status . within the nhc portion of the basin , the season officially began on may 15 , and in the cphc portion , it started on june 1 ; the season officially ended on november 30 . these dates conventionally delimit the period of each year when most tropical cyclones form in the eastern pacific basin . the strongest storm of the season was hurricane ioke , which reached category 5 status on the saffir - simpson scale in the central pacific ocean ; ioke passed near johnston atoll and later wake island , where it caused heavy damage but no deaths . the deadliest storm of the season was hurricane john , which killed six people after striking the baja california peninsula , and the costliest storm was hurricane lane , which caused $ 203 million in damage in southwestern mexico ( 2006 usd , $ 238 million 2016 usd ) . seasonal activity began on may 27 when tropical storm aletta formed off the southwest coast of mexico . no storms formed in june , though the season became active in july when five named storms developed , including hurricane daniel which was the second strongest storm of the season , as well as tropical storm emilia . during august , hurricanes ioke and john formed , as well as four other storms . september was a relatively quiet month with two storms , of which one was hurricane lane . three storms developed in october including hurricane paul and two formed in november ; this marked the second time on record , after 1961 , when more than one tropical storm developed in the basin during the month of november . seasonal forecast on may 22 , 2006 , the national oceanic and atmospheric administration 's ( noaa ) cpc ( cpc ) released their forecasts for the 2006 atlantic and pacific hurricane seasons . the pacific season was expected to be hindered by the decades - long cycle that began in 1995 , which generally increased wind shear across the basin . noaa predicted a below - normal level of activity in the eastern pacific , with 12 – 16 named storms , of which 6 – 8 were expected to become hurricanes , and 1 – 3 expected to become major hurricanes . the central pacific hurricane center 's area of responsibility was also expected to be below average , with only two to three tropical cyclones expected to form or cross into the area . they expected that neither el niño nor la niña would affect conditions significantly . on may 15 , the hurricane season began in the eastern pacific basin , which is the area of the northern pacific ocean east of 140 ° w. on june 1 , the season began in the central pacific warning zone ( between 140 ° w and the international dateline ) ; however , no storms occurred in the region until july . seasonal summary no tropical storms developed in june in the basin , which was unusual compared to the average of two storms forming during the month . since 1966 , there have been only three other seasons in which a tropical storm did not form in june , these being 1969 , 2004 , and 2007 . after such an inactive month , the tropics became active in july when five named storms developed , including hurricane daniel which was the second strongest storm of the season . during august , hurricanes ioke and john formed , as well as four other storms . september was a relatively quiet month with two storms , of which one was hurricane lane . by that time , however , el niño conditions became established across the pacific , which is known to enhance pacific hurricane activity . three storms developed in october , including hurricane paul . tropical activity within the basin in november 2006 was the most active on record , based on the accumulated cyclone energy ( ace ) index . three tropical cyclones formed , of which two became tropical storms ; only two other seasons on record , 1961 and 2015 , produced two tropical storms in the month of november . in addition , mexico was struck by four tropical cyclones in 2006 , none on the atlantic coast and all along the pacific coast . one hit baja california peninsula while the others made landfall on the mainland . an extratropical storm persisted in the extreme northern central pacific ocean in late october . it drifted over unusually warm waters up to 3 . 6 ° f ( 2 ° c ) above normal , and gradually developed convection near the center . by november 2 , quikscat satellite suggested the system attained winds of up to 60 mph ( 95 km / h ) about 900 mi ( 1450 km ) west of oregon . the system also developed an eye and an eyewall . the cyclone tracked northeastward as it gradually weakened , and dissipated on november 4 . nasa considered the cyclone to be a subtropical storm . however , as it formed outside of the territory of any monitoring organization , it was not named . operationally , the united states navy treated the system as a tropical disturbance , numbered 91c . storms tropical storm aletta on may 27 , 12 days into the season , tropical depression one formed about 190 miles ( 305 km ) south of acapulco . it slowly organized and became a tropical storm with 45 mph ( 75 km / h ) sustained winds . while named tropical cyclones in may are infrequent events , aletta marked the seventh consecutive year to have a named cyclone form in may . the storm moved toward the guerrero coast in southwestern mexico , prompting the mexican government to issue tropical storm watches between punta maldonado and zihuatanejo . aletta then became stationary over the guerrero and oaxaca coastlines , but it later turned to the west and dissipated on may 30 . aletta produced moderate rainfall across mexico , including a 24 - hour rainfall total of 3 . 94 inches ( 100 mm ) in , oaxaca on may 30 , and 3 . 78 inches ( 96 mm ) in la calera , guerrero , the next day . there were no reports of damage , flooding , or casualties . tropical depression two - e on the day after aletta dissipated , a new area of disturbed weather developed off the southwest mexican coast . high shear slowed the development of the system , although it gained enough convection and organization to be classified as a tropical depression on june 3 . the depression strengthened to near tropical storm status as it approached the coast of southwestern mexico ; however , shear persisted over the system and it weakened before dissipating on june 4 . despite never becoming a named storm , heavy rain occurred , including a total of 19 . 13 inches ( 486 mm ) measured in a 48 ‑ hour period in acapulco . mudslides and flash flooding were reported , forcing 72 people from their homes . no deaths or serious damage was reported . hurricane bud on july 11 , after over a month of inactivity , a disturbance off the peninsula of baja california developed into a tropical depression . it moved west - northwestward for its entire duration , quickly intensifying into a tropical storm and hurricane . a clear , well - defined eye developed , and bud became the first major hurricane of the season . on july 13 , the hurricane attained peak winds of 125 mph ( 205 km / h ) , although cooler waters and stable air caused a marked weakening trend . by july 15 , bud weakened to tropical depression status , and the next day it degenerated into a remnant low pressure area . the remnants of bud produced light rainfall across hawaii . hurricane carlotta a tropical wave exited africa on june 30 and moved across the atlantic ocean without development . on july 9 , while crossing central america into the eastern north pacific ocean , thunderstorm activity increased , and the system organized into tropical depression four - e early on july 12 about 290 mi ( 465 km ) south of zihuatanejo , guerrero . the large depression moved quickly to the west - northwest to the south of a ridge over northwestern mexico , and its outer rainbands moved across the coast . rainfall totals were less than 1 inch ( 25 mm ) . the depression intensified into tropical storm carlotta just six hours after forming . by late on july 12 , the storm developed banding features , and early on july 13 carlotta attained hurricane status about 430 mi ( 700 km ) south of the southern tip of the baja california peninsula . as carlotta intensified , the system became more compact , and it reached peak winds of 85 mph ( 140 km / h ) on july 13 . an eye formed in the center , and the hurricane was briefly forecast to attain major hurricane status , or a category 3 on the saffir - simpson scale . however , carlotta weakened due to increased wind shear from hurricane bud to its west , and the eye and convection deteriorated . carlotta briefly weakened to tropical storm status late on july 14 , although a decrease in shear allowed it to reintensify into a hurricane . this was short - lived as the center moved into the area of cooler waters , and carlotta again weakened to tropical storm status . late on july 15 , the circulation became separated from the convection , and carlotta weakened to tropical depression status on july 16 , and the next day generated into a remnant low . the circulation continued generally westward , dissipating on july 20 about 1500 mi ( 2400 km ) east of the hawaiian islands . hurricane daniel on july 16 , a tropical disturbance formed far to the south of the baja california peninsula and quickly increased in convective activity and organization , becoming a tropical depression . the system continued to organize and was designated as a tropical storm the next day . on july 18 , daniel attained hurricane status , and two days later underwent rapid intensification ; it reached major hurricane status and was later upgraded further to category 4 status on the saffir - simpson hurricane scale . its peak intensity was 150 mph ( 240 km / h ) . the hurricane underwent eyewall replacement cycles , which are internal mechanisms that occur in most intense hurricanes . daniel later became an annular hurricane , which allowed it to maintain category 4 status for longer than it otherwise would have . it crossed over into the central pacific early on july 24 and was predicted to affect hawaii as a tropical storm ; however , daniel encountered weak steering currents in the open ocean , causing it to slow down considerably . it rapidly degenerated to a tropical depression on july 25 , and the cphc issued its last advisory on july 26 while the storm was still well to the east of hawaii . its remnants later moved across the hawaiian islands , dropping heavy rainfall and causing flooding . west on maui recorded 3 . 87 inches ( 98 mm ) in one day , which was the highest daily rainfall total from the hurricane . tropical storm emilia the origins of emilia were from a tropical wave that developed into a tropical depression on july 21 , a short distance off the coast of acapulco . it moved generally north - northwestward , reaching tropical storm status on july 22 and passing about 175 mi ( 280 km ) southwest of manzanillo , colima . an eyewall began to form that day , and emilia reached peak winds of 65 mph ( 105 km / h ) . it briefly weakened due to wind shear , although restrengthening occurred as the storm turned toward the baja california peninsula . on july 26 , emilia again reached peak winds of 65 mph ( 105 km / h ) , and shortly thereafter it passed about 60 mi ( 95 km ) southwest of the southern tip of baja california . it weakened as it turned into cooler waters , first to tropical depression status on july 27 and then to a convective - less remnant low on july 28 . the remnants dissipated on july 31 about 495 mi ( 800 km ) west - southwest of san diego , california . in southwestern mexico , emilia produced tropical storm force winds along the coastline . rainfall in the southern portion of the baja california peninsula caused minor flooding , and gusty winds caused damage to buildings and power lines . moisture from emilia reached the southwestern united states . thunderstorms and rainfall occurred across arizona , causing flooding . in southern california , the storm dropped light rainfall , which assisted firefighters in containing a wildfire . tropical storm fabio a tropical wave crossed the west coast of africa on july 15 and entered the pacific on july 25 . convection increased on july 28 , and at 1800 utc on july 31 the system became tropical depression seven - e about 980 miles ( 1 , 580 km ) southwest of the southern tip of the baja california peninsula . six hours later , the depression was upgraded to tropical storm fabio . it moved westward due to a ridge to its north , and on august 1 fabio reached peak winds of 50 mph ( 85 km / h ) . later , the storm began weakening due to increased wind shear and dry air . on august 3 , fabio deteriorated to tropical depression status , and later that day it degenerated into a remnant low pressure area . the remnants continued westward , moving across hawaii on august 7 . although fabio did not impact land , its remnants produced heavy rainfall in hawaii . in a 24 hour period , 2 . 89 inches ( 73 mm ) of rainfall was recorded at glenwood on the island of hawaii ; this was the highest daily rainfall total for the month on the island . however , the heaviest precipitation fell on mount waiʻaleʻale on kauai , where 15 . 08 inches ( 383 mm ) fell in 24 hours ; this total alone was greater than all other monthly rainfall totals in the state . the heavy rainfall flooded the hanalei river , which forced the closure of the highway when a bridge was inundated . on oahu , the rainfall caused ponding on roadways and flooding along streams . one flooded stream stranded 24 hikers along a trail , all of whom required rescue by helicopter . tropical storm gilma on july 17 , a tropical wave exited africa and crossed the atlantic without developing . on july 25 it entered the eastern pacific , gradually developing an area of organized convection . despite marginally favorable upper - level winds , the system organized enough to be declared a tropical depression on august 1 , several hundred miles southwest of acapulco , mexico . initially , the depression tracked west - northwestward . despite wind shear in the area , the depression was upgraded to tropical storm gilma later on august 1 . the wind shear prevented further strengthening or organization , and gilma weakened to a tropical depression early on august 2 . the depression turned westward , and gilma degenerated into a remnant low by august 4 . hurricane hector a tropical wave exited africa on july 31 , and after no development in the atlantic , it crossed central america into the northeastern pacific ocean on august 10 . convection gradually increased , and a broad low pressure area developed about 375 miles ( 605 km ) south of acapulco , mexico on august 13 . the system continued to become organized , and it developed into a tropical depression around 1800 utc on august 15 about 650 mi ( 1 , 045 km ) south - southwest of the southern tip of baja california . it moved west - northwestward , located south of a ridge that extended westward from northern mexico westward into the pacific . the depression quickly intensified into tropical storm hector early on august 16 . hector was able to steadily strengthen , reaching hurricane status at 0600 utc on august 17 . it is estimated that hector reached its peak intensity of 110 mph ( 175 km / h ) at 0600 utc on august 18 , while centered about 1 , 035 mi ( 1 , 665 km ) southwest of the southern tip of baja california . hector remained a category 2 hurricane for about 24 hours . shortly thereafter , it encountered cooler waters and westerly shear , and hector steadily weakened until becoming a tropical storm by august 20 . shortly thereafter , the storm reached a weakness in the subtropical ridge , which caused it to move slowly to the northwest . by august 21 , deep convection was confined to the northeast portion of the circulation . the shear was not strong enough to completely weaken the tropical cyclone and hector remained a tropical storm with 50 mph ( 85 km / h ) winds for about 24 hours . after the remaining shower and thunderstorm activity dissipated on august 22 , the cyclone turned westward in response to the low - level easterly wind flow . hector weakened to a tropical depression at 0000 utc on august 23 , and to a remnant low six hours later . the remnant circulation of hector dissipated on august 24 about 750 mi ( 1 , 210 km ) east of the hawaiian islands . hurricane ioke the cyclone developed from the intertropical convergence zone on august 20 far to the south of hawaii . encountering warm waters , little wind shear , and well - defined outflow , ioke intensified from a tropical depression to category 4 status within 48 hours . late on august 22 it rapidly weakened to category 2 status before crossing over johnston atoll . two days later favorable conditions again allowed for rapid strengthening , and ioke attained category 5 status on august 25 before crossing the international date line . at the time , its barometric pressure was estimated at 915 mbar , thus becoming the strongest hurricane on record in the central pacific . as it continued westward its intensity fluctuated , and on august 31 it passed near wake island with winds of 155 mph ( 249 km / h ) . ioke gradually weakened as it turned northwestward and northward , and by september 6 it had transitioned into an extratropical cyclone . by then , the cyclone had lasted 19 days , reaching the equivalent of category 5 status on the saffir - simpson hurricane scale three times . the remnants of ioke accelerated northeastward and ultimately crossed into alaska . ioke did not affect any permanently populated areas in the central pacific or western pacific basins as a hurricane or a typhoon . a crew of 12 people stayed in a hurricane - proof bunker on johnston atoll during the hurricane 's passage ; the crew estimated winds reached over 100 mph ( 160 km / h ) , which damaged trees on the island but did not impact the island 's bird population . the hurricane left moderate damage on wake island totaling $ 88 million ( 2006 usd ) , which resulted from blown off roofs and damaged buildings , although the infrastructure of the island was left intact . all military personnel were evacuated from the island , the first full - scale evacuation of the island since typhoon sarah in 1967 . later , the extratropical remnants of ioke produced a severe storm surge along the alaskan coastline , causing beach erosion . hurricane ileana the origins of hurricane ileana were from a tropical wave that moved off the coast of africa on august 8 . it entered the eastern north pacific on august 16 and developed into a tropical depression on august 21 near acapulco . the depression strengthened into tropical storm ileana six hours after forming . ileana continued to strengthen , becoming a hurricane in 24 hours and a major hurricane a day after that . ileana reached its peak intensity of 120 mph ( 195 km / h ) before beginning a slow weakening phase on august 24 when it encountered cooler waters . ileana weakened a tropical depression on the morning of august 27 and quickly degenerated into a remnant low , dissipating on august 29 . as ileana was heading north along the mexican coastline , slight rainfall was recorded along the coast . there were also reports of hurricane - force winds on socorro island . one fatality was reported when a man drowned in heavy surf near cabo san lucas . hurricane john on august 28 , a persistent area of low pressure southwest of acapulco , mexico developed into a tropical depression . later that day it strengthened into a tropical storm , and it reached hurricane strength 24 hours later on august 29 . john underwent rapid intensification and reached category 3 intensity later that day and category 4 on august 30 . hours later , the hurricane underwent another eyewall replacement cycle , and subsequently weakened to category 3 status as it paralleled the mexican coastline a short distance offshore . potentially due to its eyewall replacement cycle or its interaction with land , hurricane john weakened to a 105 mph hurricane by late on august 31 , but restrengthened to a major hurricane shortly after . it made landfall near the southern tip of the baja california peninsula as a category 2 hurricane on september 1 . john continued northwestward along the eastern baja california peninsula , weakening to tropical depression status by september 3 and dissipating on september 4 in the gulf of california . along the southwestern coast of mexico , hurricane john produced heavy surf , strong winds , and heavy rainfall , which flooded roads , caused mudslides , and downed trees . along the baja california peninsula , the hurricane dropped heavy rainfall , with a 24 - hour peak of 10 . 8 inches ( 276 mm ) in los planes . the heavy rainfall caused flooding , closed roads , and caused a dam to overflow . the winds and rainfall destroyed thousands of flimsy houses across the region . across mexico , five people were killed , and damage amounted to $ 663 million ( 2006 mxn , $ 60 . 8 million 2006 usd ) . moisture from the remnants of john produced flooding across texas , which closed a ½ mile ( 800 m ) portion of interstate 10 in el paso . in southern new mexico , the rainfall caused widespread street flooding and some minor damage . tropical moisture from the storm also produced rainfall in arizona and southern california , where eight separate mudslides occurred , trapping 19 vehicles but causing no injuries . hurricane kristy on august 30 , a tropical wave located about 525 miles ( 850 km ) south - southwest of baja california became more organized and was designated as the twelfth tropical depression of the 2006 season . it strengthened into tropical storm kristy and became hurricane kristy the next day . it did not retain this status for long , partly due to its proximity to hurricane john . there was a possibility of a fujiwhara interaction between both systems , causing kristy to weaken or perhaps be absorbed into the circulation of john . this did not occur , however . kristy weakened steadily after its peak intensity and looked to be close to dissipating , but on september 3 and again on september 5 , convection flared up and it returned to tropical storm strength . after oscillating between storm and depression strength , the system degenerated into a remnant low on september 7 , which dissipated on september 8 without affecting land . hurricane lane on september 13 , a tropical disturbance located about 125 miles ( 200 km ) west - southwest of acapulco , mexico , gradually became better organized and was designated the thirteenth tropical depression of the 2006 season . the depression intensified in a favorable environment , and was upgraded to tropical storm lane later that night . as it moved parallel to the mexican coast it continued to strengthen and became a hurricane on september 15 , and a major hurricane early the next day . hurricane lane reached peak winds of 125 mph ( 205 km / h ) before it made landfall on the coast of sinaloa on september 16 . it quickly weakened over land and dissipated on september 17 . tropical storm lane produced heavy rainfall and high seas along the west coast of mexico , including acapulco where flood waters reached 16 inches ( 40 cm ) in depth . the acapulco airport also experienced flooding , though service was not interrupted . throughout mexico , the hurricane caused four deaths and $ 2 . 2 billion ( 2006 mxn , $ 203 million 2006 usd ) in damage , half of which in sinaloa where heavy crop damage was reported . an estimated 4 , 320 homes were affected by the hurricane , and 19 , 200 miles ( 30 , 000 km ) of roads and highways were damaged to some degree , including some destroyed bridges . tropical storm miriam a disturbance associated with a northerly extension of the intertropical convergence zone and a tropical wave developed a closed circulation on september 15 . it moved northeastward due to the influence from nearby hurricane lane , and organized enough to be declared tropical depression fourteen - e on september 16 while located about 500 miles southwest of cabo san lucas , mexico . it quickly strengthened , and organized into tropical storm miriam later that day . after reaching a peak intensity of 45 mph ( 70 km / h ) , vertical wind shear and cooler waters rapidly weakened the storm , and the circulation decoupled from the convection on september 17 . after turning more towards the north , miriam weakened to tropical depression status , and on september 18 it degenerated to a remnant low . the remnant circulation turned to the northwest , then to the east , and dissipated on september 21 a short distance west of baja california . no deaths are damage are associated with miriam , and only one ship recorded winds of over tropical storm force near the center . tropical depression two - c on september 19 , an area of disturbed weather associated with the intertropical convergence zone became sufficiently organized to be designated tropical depression two - c. initially , it was thought that the depression formed from the remnants of hurricane kristy , although subsequent analysis confirmed they were two separate systems . initially , the depression was in an area of favorable conditions , with little wind shear and warm waters . as a result , the cphc predicted significant strengthening to at least hurricane status . instead , a high pressure system to its north increased wind shear over the depression , causing the convection to become removed from the center . the depression weakened into a remnant low on september 20 , never reaching tropical storm status . tropical depression three - c during september , el niño conditions became established across the pacific , which produced an area of warmer waters along the international date line . a few days after tropical depression two - c dissipated , another area of disturbed weather formed , and although it was disorganized , it was also persistent . the cphc initiated advisories on tropical depression three - c on september 26 after a circulation was evident in the system . strong wind shear prevented any development , and the system dissipated on september 27 . tropical storm norman early in october , a low pressure system began to organize to the west of the mexican coast , and on october 9 it developed into tropical depression fifteen - e. it strengthened into a tropical storm the next day , but strong wind shear and low sea - surface temperatures hindered development . norman slowly began to weaken , and on october 11 it degenerated into a remnant low pressure area . turning eastward , the system combined with a new tropical disturbance off the southwest mexican coast , and slowly began to reorganize . the system was re - designated a tropical depression on october 15 just south - southeast of manzanillo , colima , although within a few hours it again dissipated . the storm brought heavy rainfall to southwestern mexico , peaking at 6 . 35 inches ( 161 mm ) in la villita , michoacán . the rainfall caused flooding and mudslides around acapulco , affecting 170 homes , of which 20 were destroyed . about 300 hectares ( 740 acres ) of crop fields sustained damage . initially there were two people missing ; however , a subsequent report indicated there were no casualties associated with the storm . tropical storm olivia on september 18 , a tropical wave exited africa and later crossed into the eastern pacific on september 29 without development . convection increased in the pacific along the wave axis , spawning a broad low pressure area on october 5 . despite the presence of wind shear , it organized enough for the nhc to initiate advisories on tropical depression sixteen - e on october 9 about 1 , 360 miles ( 2 , 190 km ) to the west - southwest of the southern tip of baja california . influenced by a high pressure system , the depression drifted northward . six hours after being upgraded to a tropical storm , olivia attained peak winds of 45 mph ( 75 km / h ) , although the convection was limited to its northern side due to wind shear . on october 11 , the convective activity diminished and olivia weakened to tropical depression status . olivia deteriorated into a remnant low on october 13 . it moved towards the east - southeast , and on october 15 was absorbed into the remnants of tropical storm norman . olivia never affected land . tropical depression four - c in the middle of october , the intertropical convergence zone extended across the central pacific ocean , resembling an extension of the monsoon trough . an area of disturbed weather formed well to the southwest of hawaii , organizing slowly for several days . late on october 13 , after the development of a low - level circulation and persistent convection , the cphc classified the system as tropical depression four - c about 750 mi ( 1 , 200 km ) southwest of honolulu , hawaii . upon being classified , the depression was located in an unusual steering flow that caused it to track eastward . due to the approach of an upper - level trough , it was expected to dissipate quickly from wind shear , although forecasters noted the possibility for the trough to provide an outflow channel , which might allow strengthening . on october 14 , strong wind shear removed the convection completely from the center , and the system degenerated into a remnant low . the remnant circulation continued slowly eastward , dissipating on october 16 . concurrently , the convection tracked northeastward ahead of the upper - level trough , which contributed to heavy rainfall and flooding on the island of hawaii on october 17 . the rainfall event coincided with an earthquake striking the area . hurricane paul hurricane paul developed from an area of disturbed weather on october 21 , and slowly intensified as it moved into an area of warm waters and progressively decreasing wind shear . paul attained hurricane status on october 23 , and later that day it reached its peak intensity of 105 mph ( 165 km / h ) , a strong category 2 hurricane on the saffir - simpson scale . a strong trough turned the hurricane to the north and northeast into an area of strong vertical shear , and paul weakened to a tropical storm on october 24 , later passing just south of the baja california peninsula . paul weakened to a tropical depression on october 25 a short distance off the coast of mexico , and after briefly turning away from the coast it made landfall on northwestern sinaloa on october 26 . paul was the third hurricane to threaten western mexico in the season , the others being hurricanes john and lane . rough surf killed two people along baja california sur , while two deaths from flooding were reported in sinaloa . paul dropped moderate rainfall across mainland mexico , including a 24 - hour total of 2 . 28 inches ( 58 mm ) in mazatlán , sinaloa . damage totaled more than $ 35 million ( 2006 mxn , $ 3 . 2 million 2006 usd ) . tropical depression eighteen - e the origins of tropical depression eighteen - e were from a tropical wave that exited the coast of africa on october 7 . it briefly spawned a low - pressure area as the wave continued westward without development . on october 20 , the wave entered the pacific ocean , developing an area of thunderstorms about four days later . by 1200 utc on october 26 , a tropical depression formed about 155 mi ( 260 km ) south of manzanillo . initially , tropical depression eighteen - e was located in an area of light wind shear , and the nhc anticipated further organization and strengthening to near hurricane status . the tropical depression initially maintained a steady westward motion away from the mexican coastline , due to a ridge north of the cyclone . by october 17 , convection had decreased , and the depression was not forecast to intensify as much . possibly due to intrusion of dry air , the circulation became exposed from the thunderstorms , and having weakened , it turned to a southward drift . by 0000 utc on october 28 , the system had weakened to a non - convective remnant low , which dissipated the following day . tropical storm rosa a tropical wave exited western africa on october 22 and continued westward into the pacific on november 2 , spawning a tropical depression on november 8 about 440 mi ( 710 km ) south of manzanillo , colima . environmental conditions appeared favorable , although wind shear removed the convection from the circulation . throughout its duration , the storm maintained a northwest track through a weakness in a subtropical ridge . by november 9 , a new area of convection persisted near the center , and a banding feature formed . despite the shear , the depression was upgraded to tropical storm rosa , although the shear prevented intensification beyond its peak of 40 mph ( 65 km / h ) . rosa remained a tropical storm for only 18 hours , becoming a tropical depression early on november 10 and dissipating later that day . rosa was the first tropical storm in the basin to develop during november since 2000 , and was also the first tropical depression to form in the month since 2002 's tropical depression sixteen - e. no impact was reported from the storm . tropical depression twenty - e a tropical wave moved off the western coast of africa on october 21 , briefly developing two weak low pressure areas before the wave crossed into the pacific ocean on november 1 . thunderstorm activity slowly increased as the wave interacted within the intertropical convergence zone . after a curved band of convection developed , it is estimated the system formed into tropical depression twenty - e around 0000 utc on november 11 , about 550 mi ( 1 , 050 km ) southwest of manzanillo . throughout its duration , the depression never completely separated from the intertropical convergence zone . when the nhc issued its first advisory on the depression , the agency predicted slight intensification to tropical storm status and for the depression to last at least two days . this was due to a forecast of gradually increasing wind shear after the first 24 hours . instead , the circulation became very elongated ; it is estimated the cyclone degenerated into a trough by late on november 11 . hurricane sergio just days after tropical depression twenty - e degenerated into an open trough , tropical depression twenty one - e developed from a tropical wave on november 13 about 460 miles ( 740 km ) south of manzanillo , colima . it steadily intensified as it tracked southeastward , reaching peak winds of 110 mph ( 175 km / h ) on november 15 . subsequently it began to weaken due to increased wind shear as it turned to the north . sergio later turned to the west , remaining well off the coast of mexico , and it dissipated on november 20 about 320 miles ( 515 km ) west - northwest of where it originally formed . sergio produced light rainfall along the coast of mexico , though its effects were minimal . the formation of sergio marked the 2006 season as the most active in 12 years and the second season in which more than one tropical storm formed in november , after 1961 . sergio set records for the month of november in the basin , becoming the third strongest hurricane , after sandra from 2015 , and kenneth from 2011 as well as the longest - lived november pacific tropical cyclone with a duration of seven days . storm names the following names were used for named storms that formed in the northeast pacific in 2006 . this is the same list that was used in the 2000 season . there were no names retired from the northeast pacific list . therefore , the same list was reused in the 2012 season . for storms that form in the central pacific hurricane center 's area of responsibility , encompassing the area between 140 degrees west and the international date line , all names are used in a series of four rotating lists . the next four names that were slated for use in 2006 are shown below , however only the name ioke was used . retirement the name ioke was retired from the north - central pacific list by the wmo in the spring of 2007 and replaced with . during the 61st interdepartmental hurricane conference , the hawaii state civil defense requested the retirement of the name daniel , citing that the storm had become memorable due to threat of damage . however , the request was denied , as the name remains on the tropical cyclone naming list . season effects this is a table of all the storms that have formed in the 2006 pacific hurricane season . it includes their duration , names , landfall ( s ) , denoted in parentheses , damages , and death totals . deaths in parentheses are additional and indirect ( an example of an indirect death would be a traffic accident ) , but were still related to that storm . damage and deaths include totals while the storm was extratropical , a wave , or a low , and all the damage figures are in 2006 usd .
