Tornadoes in the Southeastern U.S.
From April 4–5, 2022, a mesoscale convective system and numerous discrete supercells produced a swath of severe weather and several tornadoes in the Southeastern United States, including several strong, long tracked tornadoes. An EF3 tornado damaged or destroyed several homes in Bonaire, Georgia while a large EF3 tornado prompted a tornado emergency for Allendale and Sycamore, South Carolina. A violent EF4 tornado in Black Creek, Georgia resulted in one fatality as it destroyed several neighborhoods, and another large EF3 tornado caused widespread heavy tree damage northeast of Ulmer, South Carolina. More severe storms occurred across a large portion of the Southeast ahead of a cold front on April 6–7, with more tornadoes reported in South and Central Georgia and further south into Florida, all of which were weak. Along with the one tornadic death, trees felled by straight-line winds killed one person each in Louisiana and Texas.
Meteorological synopsis.
April 4–5.
For the third time in a three-week period, environmental conditions across the Southeastern United States became favorable for a widespread severe weather and tornado outbreak during the early days of April. For days, forecasters at the Storm Prediction Center advertised the eastward progression of a broad upper-level trough into the South Plains region. As this occurred, they forecasted the development of an area of low pressure in northwestern Texas along a stalled front. To the south of this northward-propagating boundary, surface temperatures rose to around while rapidly-cooling air aloft led to the development of 1,500–2,000 J/kg mid-level convective available potential energy (CAPE). With modest advection of warm air and an eroding capping inversion, widespread convective development overspread northwestern Texas and southwestern Oklahoma, with a primary risk of very large hail and damaging wind gusts. Farther southeast in the vicinity of the Dallas–Fort Worth metroplex, forecasters warned of the potential for a higher tornadic threat given an approaching shortwave trough, better northward transport of moisture, and a strengthening of low-level wind fields. A long-lived embedded supercell developed south of the metroplex, producing multiple tornadoes. One of tornadoes reached EF2 intensity near Egan, causing severe damage and injuring one person. Otherwise, widespread convective activity congealed into a southeast-moving mesoscale convective system across eastern Texas and Louisiana through the overnight hours, where the SPC had placed a level 3 Enhanced risk for the threat of damaging winds. Dozens of severe wind gusts were recorded.
Into the morning hours, the progressive squall line lost some of its intensity as it moved across the Ark-La-Tex region. However, with increasing wind fields and deeply moist dew points above , the SPC anticipated re-intensification of this feature through the afternoon, plus an attendant risk for discrete supercells in advance of the line. Accordingly, they yet again outlined a level 3/Enhanced risk of severe weather, including a more substantial threat for tornadoes, some EF2 or stronger, from the Mississippi–Alabama border eastward to the coastal border of Georgia and South Carolina. Despite only modest mid-level cooling, the environment became increasingly unstable as temperatures warmed in excess of , resulting in mid-level CAPE into the 500–1,500 J/kg range. A bowing complex evolved across southern Alabama into Georgia while leading supercells evolved in advance of the line, resulting in widespread damaging winds and numerous tornadoes, including multiple strong tornadoes. One high-end EF3 tornado embedded within the line destroyed multiple homes in Bonaire, Georgia, causing an injury. Farther northeast across South Carolina, a south-southwesterly low-level jet up to overspread an unstable and moist environment, leading to the concern for supercells capable of producing strong tornadoes. Indeed, multiple discrete storms developed ahead of the advancing squall line in the warm sector across eastern Georgia and the South Carolina Lowcountry. These cells quickly intensified as they overspread the region, and produced multiple significant tornadoes, including multiple long-track, strong wedge tornadoes. A low-end EF3 tornado prompted the issuance of a tornado emergency for Allendale, South Carolina, while a violent EF4 tornado destroyed numerous homes and caused a fatality in Black Creek, Georgia. A high-end EF3 tornado then touched down in Allendale County near Ulmer a few hours later, before continuing into Bamberg and Orangeburg counties, causing substantial tree damage along its path. An EF2 tornado also inflicted heavy damage along in the western, northwestern, and northern parts of Manning, South Carolina. By the evening hours, these cells began to merge with the progressive squall line as it shifted into a more stable air mass and approached the Atlantic coastline.
April 6–7.
After the previous days' storms advanced into the Atlantic Ocean, a new severe weather system developed over many of the same areas in Alabama, Georgia, and South Carolina. Remnants of storms from the previous day gave way for abundant moisture overspreading the area. This, combined with the presence of upper 60s F dew points and CAPE values of 2000-3000 J/kg, created a highly unstable atmosphere, conductive for severe weather. Given the favorable parameters for severe weather, the Storm Prediction Center issued a large Enhanced risk area, encompassing areas centered around Georgia, central and northeastern portions of Alabama, eastern Tennessee, extreme western North Carolina, and southern South Carolina. The outlook highlighted the high probabilities of damaging wind gusts to be the primary threat of the event, but a 10%, unhatched corridor for tornadoes was also situated along central Georgia.
As the evening advanced, destabilization in the area kept growing, and a long chain of thunderstorms developed along a corridor in central and southern Georgia. As such, the SPC issued a large tornado watch for central counties in Georgia, discussing the moderate possibilities for tornadoes to develop, but strong tornadoes were not thought to be likely. As this line segmented on the early evening, multiple supercell thunderstorms developed and matured on the area as they entered the favorable environment in central Georgia. As such, multiple tornadoes developed as a result. An EF1 tornado that developed in Lee County was documented by multiple storm chasers as it caused damage near the town of Cordele. Multiple other weak tornadoes were reported from these supercells along with numerous reports of damaging winds. More severe storms formed in Florida and the Eastern Carolinas during the afternoon of April 7, but no tornadoes were reported. The severe threat ended after the storms either moved offshore or weakened below severe limits.
Confirmed tornadoes.
Pembroke–Ellabell–Black Creek, Georgia.

This large, violent wedge tornado touched down just southwest of Pembroke at 5:18 p.m. EDT (21:18 UTC) and quickly strengthened to EF2 intensity as it moved into town. It inflicting significant damage to the Bryan County Courthouse, the Bryan County Jail, the Bryan County Planning and Zoning office, destroyed a couple of older wood-frame homes, damaged multiple other structures and several vehicles, and downed many trees and power lines. Moving east-northeast, the tornado exited the town and maintained EF2 intensity as it crossed over a wooded, marshy area, flattening a swath of trees, destroying an outbuilding, and heavily damaging a house. After moving north of Ellabell and entering the small community of Black Creek, the tornado rapidly intensified and moved through George D. Hendrix Park at EF3 intensity. A large recreation center building was heavily damaged, reinforced concrete light poles were snapped, multiple large trees were snapped, denuded, and partially debarked, and turf at a football field in the park was also damaged. The tornado then grew to its peak width and reached its peak intensity of mid-range EF4 as it struck the Park Place subdivision. Several well-built homes here were destroyed, four of which were leveled, including two that were completely swept away with only their bare concrete slab foundations remaining. Multiple other homes sustained major damage, cars were tossed and damaged, and a large portion of the roof from the recreation center at George D. Hendrix Park landed on a house in this area, approximately away from where it originated. Multiple serious injuries occurred, some of whcich had to be rescued from their destroyed.
The violent tornado then moved into the Black Creek Golf Course, where many trees were snapped and partially debarked, a golf cart barn was destroyed, a clubhouse building sustained severe structural damage, and some homes sustained considerable roof and exterior damage. The tornado then weakened but remained strong as it moved further to the east-northeast, mowing down more trees as it moved through another wooded and marshy area. It then struck a mobile home park at EF3 intensity, where several well-anchored mobile homes were destroyed after being thrown or rolled. Some outbuildings were destroyed, and storage trailers were overturned as well. A woman was killed in one of the destroyed mobile homes, and multiple injuries occurred throughout this area. The tornado then weakened further as it crossed I-16 and continued eastward. The tornado caused EF1 damage to some large warehouses, ripped part of the roof off a AGCO company building, and inflicted considerable damage to trees before dissipating after crossing the road at 5:33 p.m. EDT (21:33 UTC), having traveled . In addition to the fatality, at least 12 people were injured. Coupled with the EF4 tornado that struck Newnan the previous year, this event marked the first time that F4/EF4 tornadoes had struck Georgia in back-to-back years since modern records began in 1950.
Non-tornadic impacts.
The severe squall line that formed in Central Texas on April 4 moved eastward, producing a swath of damaging straight line winds in Kaufman County between Scurry and Kemp. There was damage to trees and signs along with minor roof damage. Another area of even stronger winds of winds moved across southeastern Van Zandt County. Trees were damaged, metal structures/barns were damaged or destroyed, and the roofs of some homes were damaged. Another area of wind damage struck Whitehouse, knocking down numerous trees, four of which landed on homes. A fatality was confirmed in one of the houses. The severe squall line continued to produce wind damage as it moved into southern Arkansas and northern Louisiana early on April 5. Northeast of Minden, Louisiana, a motorist was killed when they struck a tree that had fallen across US 79. Although an EF1 tornado was confirmed in Union Parish, the entire southern half of the parish suffered heavy straight-line wind damage. Severe storms also formed ahead of the line, producing wind damage and large to very large hail in the central portions of Mississippi and Alabama. The squall line produced straight-line winds south of Beatrice, Alabama prior to producing an EF1 tornado to the northeast. Pine trees were snapped or uprooted due to these strong winds.
The tornadic thunderstorms that day also produced other severe weather. The storm that produced the Pembroke–Black Creek, Georgia EF4 tornado produced baseball-size () hail that damaged vehicles north of Ellabell. The storm was tornado warned until it moved into the Atlantic Ocean in Charleston, South Carolina, but no tornadoes were confirmed. However, severe winds downed many trees and power lines from Rincon, Georgia through Beaufort, South Carolina to Charleston. In Charleston, wind gusts of were observed in Charleston Harbor. Several aircraft on the USS Yorktown were moved, three trees at the Civil War Memorial were blown down, and the west stand of the Patriots Point Soccer Complex on Patriots Point was heavily damaged. Isolated severe storms also occurred in Missouri, northern Arkansas, and South Texas. A severe storm east of Kansas City near Pilot Grove, Missouri produced winds, knocked down power lines on Route 135, and ripped part of the roof off a barn. The storm also triggered a tornado warning, but no tornadoes were confirmed. Another severe storm in northern Arkansas produced multiple instances of large hail into the overnight hours of April 5–6. The storm was also briefly tornado-warned, but no tornadoes touched down.
On April 6, a damaging windstorm struck Laurel County, Kentucky in the East Bernstadt area. Trees, power poles, and homes were damaged, the steeple of a church was blown down, and two barns collapsed. A wind gust of was also recorded in the town. Another windstorm in Beaufort, South Carolina blew down trees and power lines. Other areas of wind damage along with large hail were recorded elsewhere in the Southeastern United States as well. On April 7, severe wind gusts in the Jacksonville, Florida metropolitan area blew down trees. Large trees were also blown down in the Orlando metropolitan area and a home in the area lost a portion of its metal roof. An wind gust was also recorded
