AVIATION
(18Z TAFS)
ISSUED AT 244 PM EDT SUN APR 12 2026
VFR AND DRY CONDITIONS WILL PREVAIL WITH NORTHEASTERLY SURFACE

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.
