Tropical Storm Jerry (2007)

Tropical Storm Jerry was the tenth named storm of the 2007 Atlantic hurricane season. It was a very short-lived storm over the north-central Atlantic Ocean, lasting less than 48 hours, half of that time as a subtropical cyclone. It was never a threat to land. Jerry formed as a subtropical depression on September 22 from a non-tropical low pressure area over the central Atlantic. Then next day, it was upgraded to a tropical storm. After attaining tropical characteristics, the cyclone peaked with winds of 40 mph (65 km/h), and began to weaken on September 24. It completely dissipated on September 25.

Meteorological history
The origins of Jerry can be traced back to a non-tropical low pressure area over the central Atlantic on September 21. The system erratically meandered over the north-central Atlantic over for two days, gradually developing deeper convection (thunderstorm activity) and gaining in organization. On September 22, the system had become more organized, and the National Hurricane Center mentioned the potential existed for tropical or subtropical development in the area. Late that evening, it had been determined that a subtropical depression had formed, as a warm core had developed but the system was still involved with an upper-level low, and its strongest winds were well removed from the center. Early on September 23, both satellite estimates and QuikScat data determined that the depression had strengthened into Subtropical Storm Jerry, despite the lack of a well-defined inner core. The storm slowly acquired tropical characteristics including a better-defined warm core, and became fully tropical that evening as a weak and sheared tropical storm with 40 mph (65 km/h) winds over a small radius.

Tropical Storm Jerry began to weaken once again early on September 24 as it accelerated northeastward over cooler waters with sea surface temperatures below 24°C (75°F). It remained a tropical storm until later that morning, when it weakened to a tropical depression ahead of a powerful cold front with little deep convection remaining in the system. Jerry remained a tropical depression as the cold front approached and began to absorb the system that afternoon as it continued to accelerate northeastward. That evening, a QuikScat pass determined that Jerry had opened up into a trough which was being absorbed into the larger frontal system. It completely dissipated by early on September 25.

Impact and naming
The storm never approached land during its lifespan, and no damage or casualties were reported. No ships were impacted by the storm. Jerry was one of eight Atlantic storms in the month of September, which tied with both the 2002 season and the 2010 Atlantic hurricane season for the record of the most during the month.
