A "subtropical" designation means it has characteristics of tropical storm but now lacks the potential of becoming a hurricane.
Yesterday, the National Hurricane Center released its 2018 hurricane forecast, and they expect 2018 to be an "active season", with between 10 to 16 named storms, five to nine of which being hurricanes. The system could be upgraded to Tropical Storm Alberto in the next day or so if the system strengthens.
At the meeting, Gov. Scott urged Floridians to watch the weather closely and make a plan. Forecasters say heavy rains are likely across western Cuba, much of Florida and the northern Gulf Coast into early next week.
A subtropical storm has characteristics of both a tropical and non-tropical storm.
Severe storms on Thursday raged from Minnesota to Georgia, creating flooding and damaging trees and homes. The system is not expected to directly impact Virginia, until maybe the end of next week. Other parts of the South would likely be affected as well. Temperatures will be in the upper 90s Memorial Day weekend and will approach triple digits next week. The main threat from this system continues to be its heavy, flooding rain. The storm is forecast to come closest to South Florida late Saturday night and early Sunday morning - although it will remain well out in the Gulf of Mexico. The rain is also expected to threaten building structures in low-lying areas.
