Tropical Storm Jose (2023)

Storm Active: August 29-September 1

On August 19, a tropical wave moved off the African coast over the tropical Atlantic ocean. It moved across the Cabo Verde islands on August 21, bringing scattered downpours. The system moved slowly west-northwestward for several days. Conditions were marginally favorable, but the disturbance could not quite take advantage enough to be designated a tropical cyclone. It nonetheless plodded along, turning toward the north and entering the subtropical Atlantic. At that time, development was no longer expected, but the system make an unlikely comeback and finally became Tropical Depression Eleven on August 29, by which time it was located around 850 miles east-southeast of Bermuda.

The depression meandered for the next day and changed little in organization. Late on August 30, though, it began to pick up speed toward the north, feeling the influence of the large Hurricane Franklin approaching from the west. Somewhat surprisingly, the system's thunderstorm activity became significantly better organized early on the 31st, and it was upgraded to Tropical Storm Jose. The storm even managed to strengthen some more that night, reaching a peak winds of 60 mph.

On September 1, the small storm began to rocket northward, rapidly spiraling in toward the much larger circulation of Franklin, which became extratropical that afternoon. Despite increasing shear from the larger system, Jose maintained its identity through that evening and produced a trail of thunderstorm activity in its wake. Shortly after that, however, the system was at last absorbed into ex-Franklin.
