The National Hurricane Center says Tropical Storm Sally has formed as the system moves off of Florida into the Gulf of Mexico.
It is forecast to head for the Gulf Coast somewhere from Louisiana to the Florida Panhandle.
"Tropical storm or hurricane watches... could be issued for a portion of that area later today."
Sally is expected to get stronger as it moves through the Gulf.
"Additional strengthening is expected over the next couple of days, and Sally is forecast to become a hurricane by late Monday."
Landfall is currently forecast for near the Louisiana / Mississippi state line Tuesday.
"Sally is expected to produce through Tuesday rainfall of 3 to 6 inches with localized amounts of 8 inches along the Gulf Coast from the Florida Peninsula to southeast Louisiana."
