Early on September 23, a subtropical depression formed from a previously extratropical low about 1060 miles (1710 km) west of the Azores. It quickly strengthened into Subtropical Storm Jerry later that morning while remaining far from land. It transitioned into a fully tropical storm early on September 24, but weakened the same day as it moved over cooler waters. As it accelerated northward, it strengthened back into a tropical storm and reached its peak intensity of 45 mph (75 km/h) late on September 24. Shortly afterward, Jerry was absorbed into a larger extratropical low.
