8NM W Passage Key Inlet FL

Synopsis: Warm moist air over the relatively cooler shelf waters will create conditions favorable for sea fog to develop through tonight...with the best chance over the central and northern waters. A cold front will move across the waters Wednesday night with increasing north winds and building seas which will likely create advisory level conditions into Thursday. Winds and seas will begin to subside Thursday night. High pressure will hold over the waters Friday through Sunday with benign conditions expected. A cold front will push across the waters Sunday night with winds and seas again increasing in the wake of the front. Exercise caution levels likely with possible advisory level winds.
