A WET WET SATURDAY FOR THE FLORIDA KEYS! PORTIONS OF THE ISLAND
CHAIN IN THE UPPER AND LOWER KEYS SAW RADAR ESTIMATES OF 2 INCHES
AN HOUR AND BOTH REQUIRED FLOOD ADVISORIES FOR THESE HEAVY
DOWNPOURS OVER THE LAST HOUR OR SO. OUTSIDE OF THOSE AREAS, A
MAJORITY OF THE ISLAND CHAIN HAS REMAINED DRY. ANY SHOWER THAT
DEVELOPS IS CAPABLE OF VERY HEAVY DOWNPOURS AS THEY AREN'T VERY
FAST MOVING AND THE ATMOSPHERE IS VERY SATURATED. THIS MORNING'S
12Z KKEY SOUNDING CONFIRMS THAT WITH JUST OVER 2 INCHES OF PWAT
MEASURED. WHILE ANY OF THESE SHOWERS CAN BECOME THUNDERSTORMS, THE
MAIN THREAT OF THE DAY WILL REMAIN FLOODING FROM THE HEAVY
RAINFALL AS THESE SHOWERS HAVE NOT BEEN PRODUCING VERY HIGH WIND
GUSTS. THE REST OF THE DAY IS EXPECTED TO LOOK SIMILAR TO WHAT HAS
BEEN OCCURRING OVER THE LAST ALMOST WEEK NOW. WET AND ICKY,
THOUGH THE SUN MIGHT TRY AND PEAK THROUGH IN SPOTS OF THE CWA. NO
CHANGES WERE NECESSARY TO THE CURRENT FORECAST PACKAGE.
MARINE
ISSUED AT 1155 AM EDT SAT SEP 6 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 IN THE EASTERN GULF AND EXTEND ACROSS THE FLORIDA
PENINSULA THROUGH THE WEEKEND AND WELL INTO NEXT WEEK. THIS TROUGH
ALONG WITH CONTINUED VERY HIGH MOISTURE LEVELS AND WEAK STEERING
CURRENTS WILL GENERALLY RESULT IN GREATER CONVECTIVE COVERAGE
THROUGH THE FORECAST.
