Timeline of the 2001 Atlantic hurricane season

The 2001 Atlantic hurricane season was an above-average Atlantic hurricane season in which fifteen named storms formed. 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 form in the Atlantic basin. The season's first tropical cyclone, Tropical Storm Allison, formed on June 5 while the season's final system, Hurricane Olga, dissipated on December 6.

The season produced seventeen tropical depressions, of which fifteen intensified into tropical storms, nine became hurricanes, and four strengthened into major hurricanes. The two most significant storms of the year, in terms of loss of life and damage, were Tropical Storm Allison and Hurricane Michelle. Forming over the northwestern Gulf of Mexico, Allison produced widespread heavy rainfall along its path (most notably across Texas and Louisiana), killing 41 people and inflicting $9 billion (2001 USD) in damage. Following the season, Allison became the first tropical storm to have its name retired by the World Meteorological Organization. Hurricane Michelle was the most intense cyclone of the 2001 season, with winds reaching 140 mph (220 km/h). The storm's impacts extended from the Caribbean Sea to the Bahamas and were most severe in Cuba, cementing its status as one of the costliest cyclones on record there.

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