Tropical Storm Conditions and Excessive Rainfall for Florida on Monday
Tropical Storm Emily has formed over the eastern Gulf of Mexico and will move inland across western Florida today. Deep tropical moisture and favorable low level winds will allow for some rotating thunderstorms within Emily's rainbands. A brief tornado or waterspout cannot be ruled out with some of these storms. Along the coast of western Florida, winds of 35 knots with gusts in excess of 45 knots are forecast, allowing for swells of 5-8 feet. Rainfall amounts will range 2-3 inches with locally higher amounts in excess of 5 inches.
