The 2001 Atlantic hurricane season was a fairly active

The Atlantic hurricane season is the period in a year from June through November when tropical cyclones form in the Atlantic Ocean, referred to in North American countries as hurricanes, tropical storms, or tropical depressions. In addition ...
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

, 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 153 fatalities, and $11.44 billion (2001 USD) in damage. Due to their severe damage, the names ''Allison'', ''Iris'', and ''Michelle'' were

Pre-season forecasts
On December 7, 2000, Gray's team issued its first extended-range forecast for the 2001 season, predicting above-average activity (13 named storms, 8 hurricanes, and about 4 of Category 3 or higher). It listed a 63 percent chance of at least one major hurricane striking the U.S. mainland. This included a 43 percent chance of at least one major hurricane strike on the

Mid-season forecasts
On August 7, 2001, Gray's team issued their first mid-season forecast for the 2001 season, keeping the forecast number at 12 named storms, with 7 becoming hurricanes and 3 becoming a major hurricane, noting that sea surface temperatures and sea level pressures continued to be favorable for above-average hurricane activity. The estimated potential for at least one major hurricane to affect the U.S. was upped slightly once again to 69 percent; the East Coast potential also went up slightly to 50%, and from the Florida Panhandle westward to Brownsville, Texas, the probability was also upped slightly.
On August 8, 2001, NOAA revised its season estimate slightly upwards to nine to twelve named storms, of which 6 to 8 were to be hurricanes, and 2 to 4 major hurricanes. The agency noted that sea surface temperatures continued to be favorable for above-average hurricane activity, and due to the likelihood that El Nino would not develop during the peak of the season, there was a reduced likelihood of a below-average year.

ACE is, broadly speaking, a measure of the power of the hurricane multiplied by the length of time it existed, so storms that last a long time, as well as particularly strong hurricanes, have high ACEs. It is only calculated for full advisories on tropical systems at or exceeding 39 mph (63 km/h), which is the threshold for tropical storm status.

In this area, flooding related to Allison destroyed or severely damaged more than 14,000 homes,
while at least 51,430 others experienced some degree of damage. Floodwaters also entered over 95,000 vehicles and 1,700 businesses.
The storm killed 41 people, including 27 who drowned. Overall, Allison caused about $8.5 billion in damage (2001 USD), making it the costliest and second-deadliest tropical storm on record in the United States.
Tropical Depression Two
A tropical wave emerged into the Atlantic from the west coast of Africa on July 7. Moving westward, the system displayed signs of a weak low-level circulation beginning on July 10, and after deep convection formed on the following day, a tropical depression developed around 18:00 UTC about east of the

Hurricane Felix
A tropical wave spawned a tropical depression on September 7 near the Cape Verde islands, which degenerated back into a tropical wave the next day due to strong shear. It redeveloped back into a tropical depression on September 10, and intensified into Tropical Storm Felix the next day while tracking generally northward. By September 13, it intensified into a hurricane, and subsequently it underwent rapid deepening, becoming a major hurricane on September 14 with peak winds of . By that time, Felix had turned to the northeast, and subsequently entered an area of unfavorable conditions. The hurricane gradually weakened, deteriorating to a tropical storm on September 17. Cool waters and higher wind shear caused additional weakening while Felix nearly stalled to the southwest of the Azores. Late on September 18, the storm weakened to a tropical depression, and early the next day Felix dissipated.

Titusville on September 15, accelerated to the northeast, and strengthened, becoming a Category 1 hurricane two days later. Colder water temperatures then weakened Gabrielle to a tropical storm on September 18, followed by an extratropical transition on September 19 well south of Newfoundland. The extratropical low was absorbed by a larger extratropical low over the far north Atlantic on September 21.
Hurricane Gabrielle produced moderate winds along coastal areas of western Florida, reaching at Venice.

. It moved slowly northward as convection organized into a ring around the center. As a result of a ship reporting hurricane-force winds near the center, and due to the development of a weak mid-level warm core, the subtropical cyclone was reclassified as Hurricane Noel on November 5. Increasing westerly wind shear limited convection near the center, and Noel weakened to a tropical storm early on November 6. Progressively cooler water temperatures contributed to weakening, and Noel became extratropical later on November 6 about 330 mi (530 km) southeast of Newfoundland. The extratropical remnant continued to the northeast and was absorbed by a larger extratropical storm later that day.
