DISCUSSION
ISSUED AT 426 AM EDT SAT AUG 16 2025
EARLY THIS MORNING, TEMPERATURES ACROSS THE ISLAND CHAIN ARE IN
THE MID 80S WITH DEW POINTS IN THE UPPER 70S. WINDS OBSERVED ALONG
THE REEF ARE EAST AT 5 TO 10 KNOTS. SKIES ARE MOSTLY CLEAR TO
PARTLY CLOUDY. KBYX DEPICTS ISOLATED SHALLOW SHOWERS STREAMING
SOUTHWARD THROUGH MAINLY THE DEEP GULF AND DISTANT STRAITS OF
FLORIDA. OVERALL, CONDITIONS ARE TYPICAL FOR AN AUGUST WET SEASON;
WARM, HUMID, AND MILD, ASIDE FROM BRIEF SHOWER PASSAGES.
A BROAD SUBTROPICAL RIDGE OVER THE WESTERN ATLANTIC WILL REMAIN
THE DOMINANT FEATURE ACROSS THE FLORIDA KEYS THROUGH EARLY NEXT
WEEK, MAINTAINING LIGHT EASTERLY, TO AT TIMES VARIABLE, BREEZES.
LARGE SCALE FORCING WILL BE WEAK, THEREFORE OUR WEATHER WILL
FOLLOW OUR TYPICAL LATE SUMMER KEYS PATTERN WITH OCCASIONAL
ISOLATED CONVECTION. HURRICANE ERIN IS FORECAST TO STAY WELL EAST
OVER THE ATLANTIC, WITH NO DIRECT IMPACTS TO OUR CWA EXPECTED,
THOUGH PERIPHERAL MOISTURE COULD SLIGHTLY INFLUENCE LOCAL RAIN
CHANCES MID WEEK. STAY TUNED FOR ANY UPDATES.

ADVISORIES ARE CURRENTLY IN EFFECT IN THE FLORIDA KEYS WATERS.
FROM SYNOPSIS, A BROAD RIDGE STRETCHING FROM THE NORTH ATLANTIC
WESTWARD ACROSS THE FLORIDA PENINSULA WILL RESULT IN LIGHT TO
GENTLE EASTERLY BREEZES ACROSS THE KEYS COASTAL WATERS FOR THE
REST OF THE WEEKEND, AND EARLY NEXT WEEK. RAIN AND THUNDER CHANCES
WILL BE NEAR TO SLIGHTLY BELOW NORMAL FOR THIS TIME OF YEAR.

PREVAIL AT BOTH EYW AND MTH THROUGH THE TAF PERIOD, ISOLATED
SHOWERS AND THUNDERSTORMS WILL BE POSSIBLE, MAINLY IN THE LATE
OVERNIGHT AND EARLY MORNING PERIODS. DUE TO THE LACK OF COVERAGE
AND UNCERTAINTY IN TIMING, VCSH IS CURRENTLY LEFT OUT OF THE TAFS,

ISSUANCE. NEAR-SURFACE WINDS WILL REMAIN GENERALLY EASTERLY AT 4
