THE FLOW ACROSS THE KEYS REMAIN NORTHWEST TO NORTH IN WAKE OF A
RELATIVELY RECENT COLD FRONT PASSAGE. AS A RESULT, CONDITIONS ARE
DRY AND STABLE WITH TEMPERATURES NEAR 70 AND DEW POINTS DOWN NEAR
60. THE WIND FIELD ACROSS OUR AREA HAS BEEN QUITE VARIED. THIS IS
DUE TO THE COMBINED EFFECT OF MAINLAND DAY TIME HEATING, A HIGH
OVER THE GULF, AND TROUGHING OVER FLORIDA AND THE BAHAMAS. BREEZES
HAVE BEEN FRESH OVER MOST OF THE KEYS, WHILE AT THE SAME TIME,
NEARLY NON EXISTENT NEAR NORTH KEY LARGO AND OCEAN REEF. EXPECT
THE NORTHERLY BREEZES TO EVEN OUT IN THE GENTLE TO MODERATE RANGE
OVERNIGHT AS DAY TIME HEATING WEARS OFF AND A MODEST DRAINAGE
FLOW SETS UP. REGARDLESS OF SPEED, THE LOOSELY NORTHERLY FLOW WILL
MAINTAIN MILD CONDITIONS. EXPECT MOSTLY CLEAR SKIES WITH LOWS IN
THE UPPER 60S AND DEW POINTS NEAR OR SLIGHTLY ABOVE 60. RAIN
CHANCES WILL REMAIN ESSENTIALLY NIL.
MARINE
ISSUED AT 1030 PM EDT WED APR 9 2025
THE COMBINATION OF EARLIER DAY TIME HEATING WITH RIDGING OVER THE
GULF AND TROUGHING OVER FLORIDA AND THE BAHAMAS HAS GENERATED
QUITE THE SPECTRUM OF NORTHWEST TO NORTHERLY BREEZES THIS
EVENING. WINDS ARE FRESH OVER THE WESTERN TWO THIRDS OF OUR MARINE
ZONES AND ALMOST NON EXISTENT OVER THE EASTERNMOST ZONES. AS A
RESULT, A SMALL CRAFT ADVISORY REMAINS IN EFFECT FOR ALL WATERS
WEST OF CRAIG KEY. WINDS ARE EXPECTED TO DIMINISH AS THE EFFECTS
OF DAY TIME HEATING WEAR OFF. ADVISORIES WILL LIKELY BE LOWERED BY
MORNING.
