2001 Atlantic Hurricane Season

The 2001 Atlantic hurricane season was a fairly active Atlantic hurricane season that produced 17 tropical cyclones, 15 named storms, nine hurricanes, and four major hurricanes. The season officially lasted from June 1, 2001, to November 30, 2001, dates which by convention limit the period of each year when tropical cyclones tend to form in the Atlantic Ocean basin. The season began with Tropical Storm Allison on June 4, and ended with Hurricane Olga, which dissipated on December 6. The most intense storm was Hurricane Michelle, which attained Category 4 strength on the Saffir–Simpson Hurricane Scale.

The most damaging storms of the season were Tropical Storm Allison, which caused extensive flooding in Texas, Hurricane Iris which struck Belize, and Hurricane Michelle, which affected several countries. Three tropical cyclones made landfall on the United States, three directly affected Canada, and three directly affected Mexico and Central America. Overall, the season caused 105 fatalities, and $7.1 billion (2001 USD; $9.32 billion 2012 USD) in damage. Due to their severe damage, the names Allison, Iris, and Michelle were retired by the World Meteorological Organization.
