Tropical Storm Jerry was a short-lived tropical storm that formed in the latter half of the 2001 Atlantic hurricane season. Forming as a tropical depression from a tropical wave on October 6 near Barbados, Jerry intensified into a tropical storm early the following day on October 7 while initially located under an environment of weak vertical wind shear.[1] After reaching its peak of 50 mph (80 km/h), Jerry passed just south of Barbados late on October 7 and through the Windward Islands on October 8. Shortly after entering the eastern Caribbean Sea, moderate upper-level wind shear affected Jerry's upper-level outflow, and the cyclone weakened to a depression shortly afterwards. Deterioration in organization continued, and Jerry dissipated while moving rapidly westward well south of Puerto Rico. Jerry caused minimal effects in the Lesser Antilles.
Meteorological history

Located 620 mi (1,000 km) east-southeast of Barbados, the twelfth depression of the season moved just north of due west, steered quickly at 20 to 25 mph (40 km/h) by a ridge of high pressure in the lower to middle troposphere.[1] At 5 p.m. AST later on October 6, the NHC noted that the depression was nearing tropical storm strength.[3] Shortly after, a burst of heavy convective thunderstorms developed over the ill-defined low-level center, and as organization improved, the system was upgraded to 40 mph (65 km/h) Tropical Storm Jerry around midnight on October 7.[1][4][5] Located within an environment of weak vertical wind shear, Jerry strengthened further, with its maximum sustained winds reaching their estimated peak of around 50 mph (80 km/h) as Jerry approached the Windward Islands[1] later on October 7.[6][7] Jerry passed just south of Barbados at its peak intensity, followed by a slowing of forward speed and jog to the northwest as Jerry entered the Windward Islands early on October 8.[1] Reconnaissance aircraft also indicated a possible reformation of the center, as data indicated multiple low-level rotations on a northeast to southwest axis.[1]
As Jerry entered the eastern Caribbean Sea early on October 8 after bypassing St. Vincent, its forward speed increased to 25 mph (40 km/h), and reconnaissance aircraft observations indicated a broad circulation with several small rotations but an ill-defined low-level center.[1][8] Later, satellite observations indicated that the storm was poorly organized, with an elongated cloud mass and displaced secondary center to the northwest.[9] Moderate vertical wind shear from the northwest developed, disrupting Jerry's upper-level outflow.[1] 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.[10] Jerry then dissipated shortly afterward approximately 230 miles south of Puerto Rico, with the remnants moving westward.[1]
Preparations and impact

Due to the tropical cyclone's short life, overall track errors in model guidance were not significant, and most models accurately indicated Jerry's westward to west-northwest course into the Caribbean Sea.[1] Most models and official forecasts did not anticipate Jerry's dissipation, and numerous models indicated the system would reach hurricane status within two to three days under favorable conditions.[1] Prior to Jerry's formation, a tropical storm watch was issued for Barbados at 5 p.m. EDT on October 6 because of forecasts that indicated the depression could intensify to tropical storm intensity.[11] As the depression intensified to tropical storm status and moved closer to the Windward Islands, a tropical storm watch was issued for Tobago by the government of the island nation and for nearby Grenada by the Trinidad and Tobago Meteorological Service at 5 a.m. EDT on October 7.[6] A tropical storm warning was issued for Barbados at 8 a.m. EDT.[12]
Jerry caused minimal damage as it moved through the Windward Islands and Lesser Antilles. A station at Martinique reported sustained one-minute winds of 44 mph (72 km/h) on October 8.[1] The outer bands of Jerry delivered light rainfall to Grenada on October 8, but no damage was reported.[13] Some downpours and high winds were reported.[14] No ships reported tropical storm-force winds, though Barbados reported a minimum pressure of 1007 mb.[1]
