SHORT TERM FORECAST: Through midnight, widespread light rain with isolated thunderstorms will impact the Lower Keys, as well as the southeastern Gulf, Bayside waters, western Florida Straits, and Hawk Channel. Stronger storm cells will move to the west-southwest near 15 knots, as the overall rain shield drifts to the east from the offshore gulf toward the Lower Keys. In the strongest activity, mariners can expect heavy rain, wind gusts near 25 knots, occasional lightning strikes, and reduced visibilities to 2 miles or less. On land, the Lower Keys stand the best chance of receiving accumulating rainfall in the short term, with rain likely from Key West to Bahia Honda Key.
