SAHARAN AIR LAYER OVER THE KEYS WILL CONTINUE TO RESULT IN KBYX
BEING SHOWER FREE, WHICH IT HAS BEEN FOR A MAJORITY OF THE DAY.
THIS EVENING'S KKEY 00Z SOUNDING MEASURED 1.48 INCHES OF PWAT
WHICH IS BELOW THE 10 PERCENTILE FOR THE DAY, ACCORDING TO SPC
CLIMATOLOGY. THESE DRY CONDITIONS HAVE ALSO RESULTED IN MOSTLY
CLEAR SKIES FOR OUR AREA. TEMPERATURES ALONG THE ISLAND CHAIN HAVE
DIPPED INTO THE MID 80S AND WITH DEW POINTS IN THE UPPER 70S NOT
MUCH RELIEF FROM THE HEAT OF THE DAY IS POSSIBLE. ACROSS THE REEF,
MARINE OBSERVATION SITES ARE RECORDING EAST TO SOUTHEASTERLY
BREEZES OF NEAR 10 KNOTS. WHILE THE SAHARAN AIR CONTINUES TO
DOMINATE OUR WEATHER NOT MUCH IS EXPECTED TO CHANGE FOR THE NEXT
FEW PERIODS, THEREFORE, ONLY A SLIGHT CHANCE OF SHOWER IS IN THE
FORECAST FOR TONIGHT. NO CHANGES WERE MADE TO THIS UPDATE FORECAST
PACKAGE.

WHILE THERE ARE NO MARINE HAZARD PRODUCTS IN PLACE
ACROSS THE FLORIDA KEYS LOCAL WATERS, A COASTAL FLOOD STATEMENT IS
IN EFFECT FOR THE LOWER KEYS DUE TO HIGHER WATER LEVELS AROUND
TIMES OF HIGH TIDE. ANYONE ON THE WATER SHOULD BE AWARE OF REDUCED
