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
East Coast, including the Florida peninsula, and a 36 percent chance of at least one such strike on the

On April 5, 2001, a new forecast was issued, calling for 12 named storms, 7 hurricanes, and 3 major hurricanes. The increase in the forecast was attributed to the warm

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.
Seasonal summary

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.

. The depression drifted west-southwest and slowly intensified, before doubling-back to the east-northeast and strengthening into Tropical Storm Gabrielle on September 13. Gabrielle curved northeastward and reached sustained winds of before making landfall near
Venice, Florida, on the following day. After weakening slightly, Gabrielle emerged into the Atlantic near
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.

Tropical Storm Jerry
A tropical wave exited Africa on October 1, moving westward. Rainbands and convection gradually increased, and the NHC designated the system as Tropical Depression Twelve. The depression strengthened into Tropical Storm Jerry early on October 7, aided by low wind shear. Continuing westward due to a ridge to it north, Jerry strengthened further as it approached the Lesser Antilles, reaching peak winds of around . Forecast models indicated the system could reach hurricane status within two to three days under favorable conditions. Jerry passed just south of Barbados at its peak intensity, before its structure began to degrade.

St. Vincent, its forward speed increased to . Moderate vertical wind shear from the northwest developed, disrupting the upper-level outflow. Jerry continued to deteriorate, and later on October 8, aircraft data indicated the system had weakened into a broad area of low pressure with scattered squalls mainly to the east of the remnant center. Jerry then dissipated shortly afterward approximately 230 miles south of Puerto Rico, with the remnants moving westward.
The threat of the storm prompted tropical storm warnings and watches in the Lesser Antilles. Jerry caused minimal damage as it moved through the Windward Islands and
