2006 Pacific typhoon season
The 2006 Pacific typhoon season was a near-average season that produced a total of 23 named storms, 15 typhoons, and six super typhoons. The season ran throughout 2006, though most tropical cyclones typically develop between May and October. The season's first named storm, Chanchu, developed on May 9, while the season's last named storm, Trami, dissipated on December 20. Also, this season was more active, costly, and deadly than the previous season.
2005 Pacific hurricane season
The 2005 Pacific hurricane season continued the trend of generally below-average activity that began a decade prior. The season officially began on May 15 in the eastern Pacific, and on June 1 in the central Pacific; it lasted until November 30 in both basins. These dates conventionally delimit the period during each year when most tropical cyclones form in the northeastern Pacific Ocean. Activity began with the formation of Hurricane Adrian, the fourth-earliest-forming tropical storm on record in the basin at the time. Adrian led to flash flooding and several landslides across Central America, resulting in five deaths and $12 million (2005 USD) in damage. Tropical storms Calvin and Dora caused minor damage along the coastline, while Tropical Storm Eugene led to one death in Acapulco. In early October, Otis produced tropical storm-force winds and minor flooding across the Baja California peninsula. The remnants of Tropical Depression One-C in the central Pacific, meanwhile, caused minor impacts in Hawaii. The strongest storm of the period was Hurricane Kenneth, which attained peak winds of 130 mph (215 km/h) over the open Pacific. Cooler than average ocean temperatures throughout the year aided in below-average activity through the course of the season, which ended with 15 named storms, 7 hurricanes, 2 major hurricanes, and an Accumulated cyclone energy index of 75 units.
