Timeline of The 2001 Atlantic Hurricane Season

Timeline Of The 2001 Atlantic Hurricane Season

The 2001 Atlantic hurricane season was an average Atlantic hurricane season in which fifteen named storms formed. Although Tropical Storm Allison formed on June 5, the season officially began on June 1 and ended on November 30, dates that conventionally delimit the period of each year when most tropical cyclones develop in the Atlantic basin. The season's final storm, Hurricane Olga, dissipated on December 6.

The season produced seventeen tropical depressions, of which fifteen intensified into tropical storms, nine became hurricanes, and four became major hurricanes. The two most significant storms of the season, in terms of loss of life and damage, were Tropical Storm Allison and Hurricane Michelle. Tropical Storm Allison was an early season tropical storm that brought devastating rainfall to much of the Gulf Coast of the United States. The storm became the only storm in recorded history to have its name retired by the World Meteorological Organization. Hurricane Michelle was the strongest hurricane during the season, with winds reaching 140 mph (220 km/h), Category 4 hurricane status on the Saffir–Simpson Hurricane Wind Scale. Michelle produced torrential rainfall across much of Central America and Cuba before moving through the Bahamas and dissipating on November 6.

This timeline includes information that was not operationally released, meaning that data from post-storm reviews by the National Hurricane Center, such as a storm that was not operationally warned upon, has been included. This timeline documents tropical cyclone formations, strengthening, weakening, landfalls, extratropical transitions, and dissipations during the season.
