Issued at 412am EST Sat Feb 15 2025 From synopsis, a high pressure system moving off the Carolina coast tightened the pressure gradient across the Florida Keys waters to the point that Small Craft Advisories were necessary yesterday. Breezes will slowly slacken to moderate today and tonight. Prevailing easterlies will give way to variable breezes Sunday night as a cold front passes over the Keys around Monday morning. Expect breezes to freshen to moderate Tuesday night and Wednesday.
