A tropical storm watch was issued at 4 p.m. for north Florida, according to the hurricane center. A flood watch is in effect for all counties in Southwest Florida from Saturday afternoon through Monday evening.
A subtropical storm has a less defined and cooler center than a tropical storm, and its strongest winds are found farther from its center. Subtropical storms can develop into tropical storms, which in turn can strengthen into hurricanes.

Alberto is the first named tropical weather system of the hurricane season. The Atlantic Hurricane Season officially begins June 1.
