A cluster of thunderstorms developed on the east side of Hurricane
on October 1st. Moving
northward, it drifted across Cuba into the southeast Gulf of Mexico. Reconnaisance aircraft flew into
the system a couple times, and could not find a closed circulation. Just before moving inland into
southwestern Florida on the afternoon of the 3rd, the wind field finally closed off, and the subtropical
depression moved northeast across Florida, dropping a swath of heavy rainfall across Miami-Dade
and Broward counties. It eventually moved northeast off the coast of Cape Canaveral, and acquired
subtropical storm intensity. After nearly becoming a tropical system with winds close into the center
and a smaller wind field during the morning of the 6th, upper level winds out of the west and northwest
sheared the system, and it eventually moved northeastward off New England as an extratropical low.
The track of the storm is located below, denoted every six hours, using Universal Coorinated Time.
