A MOSTLY UNEVENTFUL KBYX RADAR WITH ONLY A FEW ISOLATED SHOWERS IN
OUR DISTANT STRAITS. GOES-19 SATELITTE REVEALS WHILE THE LOWER AND
MIDDLE KEYS ARE ALMOST CLOUD FREE, THE UPPER KEYS DO HAVE SOME
UPPER LEVEL CLOUDS BLOCKING SOME OF THE SUN. ONCE AGAIN THE 12Z
KKEY SOUNDING MEASURED AMPLE MOISTURE IN THE ATMOSPHERE WITH
MIMIC PRECIPITABLE WATER CONFIRMING WE ARE STILL IN A MOIST
ENVIRONMENT. TEMPERATURES ALONG THE ISLAND CHAIN ARE CREEPING FROM
THE MID 80S INTO THE UPPER 80S AS THE DAY HEATS UP. WINDS ALONG
THE REEF ARE MOSTLY SOUTH AND 5 TO 10 KNOTS. TODAY IS EXPECTED TO
BE SIMILAR TO YESTERDAY WITH SHOWERS IN A PULSE-LIKE NATURE
POPPING UP IN VARIOUS AREAS ACROSS THE COASTAL WATERS AND ISLAND
CHAIN BUT NOT AMOUNTING TO MUCH RAIN. FOR WINDS, THEY WILL REMAIN
LIGHT AND SOUTH TO SOUTHWESTERLY. NO CHANGES WERE NECESSARY TO
THIS UPDATE FORECAST PACKAGE.
MARINE
ISSUED AT 1120 AM EDT MON SEP 8 2025
A COASTAL FLOOD STATEMENT IS IN EFFECT FOR THE UPPER KEYS WATERS
AS MINOR SALTWATER FLOODING OF LOW ELEVATION STREETS AND LOTS IS
LIKELY. BEYOND THAT, NO WATCHES, WARNINGS, OR ADVISORIES ARE IN
EFFECT FOR THE FLORIDA KEYS. FROM SYNOPSIS, A SURFACE TROUGH WILL
REMAIN CENTERED OVER THE EASTERN GULF AND FLORIDA PENINSULA OVER
THE NEXT COUPLE OF DAYS. THIS TROUGH WILL BE SLOWLY SHEARED OUT
MID TO LATE WEEK. HOWEVER, THE PRESSURE FIELD IN AND AROUND THE
KEYS WILL GENERALLY REMAIN POORLY DEFINED. MOISTURE WILL REMAIN
ABOVE NORMAL. THIS ALONG WITH THE WEAK STEERING CURRENTS WILL
RESULT CONTINUED ABOVE NORMAL CONVECTIVE POTENTIAL.
