AVIATION
(18Z TAFS)
ISSUED AT 126 PM EDT SUN MAR 8 2026
VFR CONDITIONS WILL PREVAIL AT BOTH EYW AND MTH FOR THE UPCOMING
TAF PERIOD. EASTERLY WINDS WILL SLACKEN SLIGHTLY TO NEAR 10 KNOTS
AT BOTH TERMINALS, BUT EXPECT OCCASIONAL STRONGER GUSTS. SOUTH OF
THE TERMINALS, STREAMS OF CUMULUS CLOUD WILL PULSE UP OVER THE
NEARSHORE WATERS. SHORT LIVED CLOUDS MAY CAUSE MVFR TO VFR CIGS AT
EITHER TERMINAL, BUT CONFIDENCE IS NOT HIGH ENOUGH TO INCLUDE A
TEMPO.

ISSUED AT 438 AM EDT SUN MAR 8 2026
HIGH PRESSURE CENTERED NEAR BERMUDA WILL REMAIN THE MAIN DRIVER
FOR THE FLORIDA KEYS SENSIBLE WEATHER FOR THE NEXT SEVERAL DAYS.
THE WESTERN SIDE OF THIS RIDGE EXTENDS OVER FLORIDA AND INTO THE
GULF. THIS CONTINUE TO PROMOTE MODERATE TO FRESH MAINLY EASTERLY
BREEZES EARLY THIS MORNING. BREEZY CONDITIONS SHOULD DIMINISH NOT
LONG AFTER SUNRISE THIS MORNING AS THE HIGH DRIFTS A LITTLE
FURTHER EAST IN THE ATLANTIC LOOSENING ITS GRIP SOME ACROSS THE
AREA. LOW-LEVEL MOISTURE WILL REMAIN AMPLE WITH EPISODIC SHOWERS
REMAINING POSSIBLE THROUGH TONIGHT. DRIER AIR MOVES IN FOR EARLY
WEEK RESULTING IN SHOWERS BEING REMOVED FOR MONDAY THROUGH
WEDNESDAY. LOW LEVEL MOISTURE INCREASES AGAIN FOR MID TO LATE WEEK
LEADING TO A REINTRODUCTION OF SHOWER. TEMPERATURES WILL REMAIN
SLIGHTLY ABOVE NORMAL FOR THIS WEEK WITH DAYTIME HIGHS IN THE
LOWER 80S AND OVERNIGHT LOWS IN THE MID 70S. GUIDANCE IS NOT AS
STRONG WITH THE PRESSURE GRADIENT FOR EARLY TO MID WEEK,
THEREFORE, THE RISK FOR ANOTHER BREEZY PERIOD HAS DIMINISHED FOR
THE TIME BEING.
LOOKING AHEAD AT THE EXTENDED, LATE THIS WEEK, THERE REMAIN
SIGNALS FOR A COLD FRONT TO POTENTIALLY TRY AND PRESS SOUTHWARD
ALONG THE FLORIDA PENINSULA. HOWEVER, THERE REMAINS MUCH
UNCERTAINTY AS TO THE INTENSITY AND IF THIS FRONT WILL INDEED
PRESS THROUGH THE KEYS OR STALL NEARBY. MORE COMFORTABLE AND LESS
HUMID AIR MIGHT NOT BE DONE JUST YET ACROSS THE KEYS. HOWEVER, AS
WE CONTINUE TO MOVE DEEPER INTO THE SPRING MONTHS, IT GETS TOUGHER
FOR FRONTS TO MAKE IT THROUGH THE KEYS. STAY TUNED!
MARINE
ISSUED AT 438 AM EDT SUN MAR 8 2026
SMALL CRAFT SHOULD EXERCISE UNTIL WINDS DECREASE IS HEADLINED
ACROSS THE STRAITS OF FLORIDA FOR TONIGHT. FROM SYNOPSIS, HIGH
PRESSURE IS CENTERED NEAR BERMUDA WITH THE WESTERN PERIPHERY OF
THIS RIDGE EXTENDING WEST INTO FLORIDA AND THE GULF. THIS WILL
CONTINUE TO PROMOTE MODERATE TO FRESH BREEZES EARLY THIS EVENING,
ESPECIALLY ACROSS THE STRAITS, WITH MODEST SLACKENING THEREAFTER.
WHILE THE HIGH RETREATS INTO ATLANTIC EARLY THIS WEEK, BREEZES
WILL SHIFT TO THE EAST TO SOUTHEAST. A FRONTAL BOUNDARY
APPROACHING FROM THE NORTH MID TO LATE WEEK IS ANTICIPATED TO LEAD
TO FRESHENING BREEZES AND CLOCKING BREEZES FROM SOUTHEAST TO
SOUTH TO NORTH TO NORTHEAST.
