DISCUSSION
ISSUED AT 1040 PM EDT WED JUN 10 2026
A DECENT LINE OF SHOWERS HAS BEEN STRETCHED ACROSS THE COASTAL
WATERS FROM THE DISTANT STRAITS UP INTO THE GULF WATERS FOR A
MAJORITY OF THE EVENING. WITHIN THE LAST HOUR OR SO THESE SHOWERS
HAVE MOVED MORE EASTERLY NOW ALLOWING FOR SOME SHOWER ACTIVITY
OVER THE LOWER KEYS, THOUGH MEASURABLE RAIN HAS BEEN LIMITED AS OF
NOW. SOME SHOWERS IN THE STRAITS HAVE GOTTEN STRONG ENOUGH TO
BRIEFLY PRODUCE LIGHTNING STRIKES, BUT HAVEN'T BEEN ABLE TO HOLD
THEIR STRENGTH. TEMPERATURES ACROSS THE ISLAND CHAIN ARE CURRENTLY
IN THE LOWER 80S, AND NIGHTTIME MICROPHYSICS SHOWS A MOSTLY
CLOUDY AREA. ACROSS THE REEF, WINDS ARE SOUTHEASTERLY AT 10 TO 15
KNOTS. OVERNIGHT, THE CURRENT SHOWERS WILL EVENTUALLY START TO
DIMINISH IN COVERAGE AND STRENGTH AS THEY LOSE STEAM THEREFORE
LEFT THE 30% FOR TONIGHT. WINDS WILL SLIGHTLY SLACKEN AS HIGH
PRESSURE MOVES FURTHER EAST TONIGHT. NO CHANGES WERE MADE TO THIS
UPDATE PACKAGE.
MARINE
ISSUED AT 1040 PM EDT WED JUN 10 2026
NO WATCHES, WARNINGS, OR ADVISORIES ARE CURRENTLY IN EFFECT FOR
THE FLORIDA KEYS WATERS. FROM SYNOPSIS, A HIGH PRESSURE SYSTEM
OVER THE NORTH ATLANTIC WILL SUPPORT GENTLE EAST TO SOUTHEAST
BREEZES ACROSS THE FLORIDA KEYS COASTAL WATERS. SHOWER AND
THUNDERSTORM COVERAGE WILL PEAK TONIGHT, OWED TO THE PERIPHERAL
MOISTURE SURGE FROM A CENTRAL AMERICAN GYRE NEAR THE YUCATAN
PENINSULA. THE HIGH PRESSURE SYSTEM WILL MOVE FURTHER EAST INTO
THE NORTH ATLANTIC OVERNIGHT, ALLOWING BREEZES TO SLACKEN TO LIGHT
TO GENTLE. AS THE GYRE SHIFTS SLIGHTLY WESTWARD, THE MOISTURE
PLUME WILL ALSO SHIFT WEST OF THE FLORIDA KEYS MARINE ZONES,
SUPPORTING A DRIER PATTERN THROUGH THE WEEKEND.
