KEY MESSAGES
- A Small Craft Advisory remains in effect for all Florida Keys coastal waters. Breezy to windy conditions will persist for several more days. - Little to no measurable rain will maintain continued moderate drought conditions in the Florida Keys for the next week.
- Temperatures will remain seasonably warm, with highs in the lower 80s, and lows in the lower 70s.
AVIATION
(18Z TAFS) Issued at 244 PM EDT Sun Apr 12 2026 VFR and dry conditions will prevail with northeasterly surface winds of 15 to 20 knots continuing to gust up to near 25 knots. Otherwise, no significant weather impacts expected at either island terminals.
MARINE
Issued at 1125 AM EDT Sun Apr 12 2026 A Small Craft Advisory remains in effect for all Florida Keys local waters. High pressure over the area will maintain fresh to strong breezes, except across portions of the southeastern Gulf where winds will briefly decrease during the late afternoon and early evening. This is due to a Florida Shadow, and winds will quickly refreshen after sunset. Occasional light showers cannot be ruled out, but the main marine hazard for the next few days will be winds and seas.
PREV DISCUSSION
Issued at 410 AM EDT Sun Apr 12 2026 Global mean ensemble products depict very little change to the overall synoptic pattern for the next several days. The high will slowly slide eastward and fluctuate in intensity. Although there will be bouts of peaks and lulls in the winds owed to mesoscale daily land heating and cooling, generally breezy to windy conditions will continue through at least Wednesday. Forecast soundings depict a well-mixed boundary layer with a decent moisture profile up to around 900 mb, but formidable dry air aloft. While a passing shower cannot be ruled out in the easterlies over the warm waters, most island communities will likely measure little in the way of total rainfall through this period. As the high approaches the central and eastern North Atlantic late in the week, winds will modestly slacken. Other than that, confidence remains high in a mainly dry forecast through late in the work week into the weekend, and seasonably warm temperatures continuing.
