.SYNOPSIS...
Scattered showers and a few thunderstorms will be possible
tonight as a cold front slowly slides south into the coastal
waters. Offshore winds will increase in the wake of the front
tonight. Meanwhile, Hurricane Helene will continue to move north
over the eastern Gulf of Mexico, and the strong pressure gradient
on the western side of the system will augment the strengthening
offshore flow over the coastal waters zones on Thursday. Winds
will gradually diminish on Friday and shift more westerly as
Helene moves inland over the southeast US. A light to moderate
westerly flow will continue into the weekend.
