A weak cold front will move south of the waters today, and then
dissipate. A stronger cold front will move into the area waters on

late Tuesday night through Thursday morning throughout our local
waters. Breezy onshore winds and elevated seas are expected through
Thursday night as high pressure gradually weakens over the
southeastern states. Otherwise, additional rounds of thunderstorms
are forecast today through Tuesday evening with heavy rainfall and
gusty winds expected at times.
