No significant changes to the forecast for tonight. A sheared mid level shortwave trough will move E/SE across central FL in the next 24 hours. This will pull deeper moisture across south FL northward a little bit into our southern counties tonight/Sunday. This moistening trend combined with onshore flow will produce an increase in showers over the Treasure coast and adjacent Atlc. Showers will be more isolated northward into Brevard county.

Now-Tonight...Poor to hazardous conditions will last through tonight, mainly over the Gulf Stream, as seas decrease to 4-6 ft by Sunday morning offshore. The Small Craft Advisory across the nearshore waters was extended in time through 11 PM, leaving just the offshore Brevard and Treasure Coast waters in effect through 11am Sunday morning. Scattered showers are possible overnight, especially south of the Cape and Sebastian Inlet. Light onshore flow near or below 10 kt.

Sunday-Wednesday...NE flow turns NNW Monday and Tuesday, becoming onshore each afternoon. A strong cold front arrives Tuesday into Wednesday, bringing drier air and freshening NNE winds. Seas build as a result, and hazardous boating conditions are forecast to return to the local waters mid to late week. Seas 4-6 ft Sunday, 2-4 ft Monday and Tuesday, quickly building 5-8 ft Wednesday.
