SHORT TERM
(TODAY THROUGH WEDNESDAY)
ISSUED AT 1252 AM EDT TUE AUG 19 2025
HURRICANE ERIN REMAINS THE DOMINANT SYNOPTIC FEATURE THROUGH THE
SHORT TERM PERIOD AS THE SYSTEM MAKES ITS CLOSEST PASS TO SOUTH
FLORIDA TODAY. WITH ERIN BEING SO FAR REMOVED FROM SOUTH FLORIDA,
SEA BREEZES WILL CONTINUE TO DOMINATE CONVECTIVE INITIATION ACROSS
THE AREA. WHILE A FEW SHOWERS AND STORMS MAY IMPACT IMMEDIATE
COASTAL AREAS DURING THE MORNING, THE RISK FOR SHOWERS AND STORMS
INCREASES WITH THE INLAND PROGRESSION OF THE SEA BREEZES DURING THE
AFTERNOON HOURS. WITH NORTHERLY FLOW REMAINING WELL ESTABLISHED,
STORMS WILL PROPAGATE SOUTHWARD THROUGH THE DAY, MAXIMIZING COVERAGE
OVER THE SOUTHERN AND SOUTHWEST HALF OF THE AREA BY THE EVENING
HOURS.
HURRICANE ERIN CONTINUES ITS NORTHWARD PROGRESSION ON WEDNESDAY
WHICH WILL VEER SURFACE FLOW ACROSS THE AREA TO THE NORTHWEST DURING
THE MORNING HOURS AND SHOULD BECOME NEARLY STRAIGHT WESTERLY BY THE
MID AFTERNOON ON WEDNESDAY. SEA BREEZE SHOWERS AND STORMS WILL ONCE
AGAIN DURING THE AFTERNOON, EXCEPT WITH WESTERLY FLOW DEVELOPING,
THE GULF BREEZE HAS A CHANCE TO DOMINATE FOR ONCE, AND COULD LEAD TO
A FEW STORMS IMPACTING EAST COAST METRO AREAS.
HIGHS WILL RANGE FROM THE LOW TO MID 90S EACH DAY WITH APPARENT
TEMPERATURES IN THE LOW 100S.
LONG TERM
(WEDNESDAY NIGHT THROUGH MONDAY)
ISSUED AT 1252 AM EDT TUE AUG 19 2025
WESTERLY FLOW CONTINUES ON THURSDAY AND WILL POTENTIALLY
LINGER INTO EARLY NEXT WEEK, ALTHOUGH AS WE SLOWLY LOSE THE
IMPACT FROM HURRICANE ERIN, BACKGROUND FLOW WILL BECOME WEAKER AND
WEAKER EACH DAY THROUGH THE WEEKEND. EACH DAY WILL BEGIN
SIMILARLY, WITH MOSTLY SUNNY CONDITIONS PREVAILING THROUGH THE
MORNING HOURS AND EARLY AFTERNOON UNTIL THE SEA BREEZES BEGIN TO
PUSH INLAND. IN THE ABSENCE OF A SIGNIFICANT SYNOPTIC DRIVER, THE
BREEZES AND OUTFLOW BOUNDARIES CONTINUE TO RUN THE SHOW EACH
AFTERNOON THROUGH THE PERIOD. INITIAL DEVELOPMENT OF STORMS MAY BE
CLOSE TO THE EAST COAST METRO AREAS, ALTHOUGH COVERAGE SHOULD BE
MAXIMIZED ACROSS INTERIOR AREAS EACH AFTERNOON.
HIGH TEMPERATURES WILL RANGE FROM THE LOW TO MID 90S EACH AFTERNOON
WITH HEAD INDICES IN THE LOWER 100S. OVERNIGHT LOWS WILL STRUGGLE TO
DIP BELOW 80 ACROSS METRO AREAS AND WILL RANGE FROM THE UPPER 70S TO
LOW 80S. LOWS SHOULD REACH THE MID TO LOW 70S FOR INTERIOR AREAS.
AVIATION
(06Z TAFS)
ISSUED AT 1252 AM EDT TUE AUG 19 2025
VFR EXPECTED TO PREVAIL FOR THE TAF PERIOD. LIGHT WINDS CONTINUE
OVERNIGHT BEFORE INCREASING OUT OF THE NORTH EARLY THIS MORNING
AND THEN SHIFTING NE IN THE AFTERNOON. VCSH AND VCTS TODAY WITH
RISK FOR ON SITE STORMS RESULTING IN SOME REDUCED CIGS/VIS AT
TIMES. APF WILL SEE THE SAME WITH ONLY DIFFERENCE BEING A
NORTHWESTERLY WIND IN THE AFTERNOON.
MARINE
ISSUED AT 1252 AM EDT TUE AUG 19 2025
HURRICANE ERIN'S OUTER CIRCULATION WILL MAINTAIN NORTH-NORTHEASTERLY
WINDS ACROSS ATLANTIC WATERS AND NORTHWESTERLY ACROSS GULF WATERS.
WINDS WILL VEER TO A MORE NORTH-NORTHWESTERLY DIRECTION BY LATE
TUESDAY AND WESTERLY BY WEDNESDAY AFTERNOON. WAVE HEIGHTS REMAIN
AT ONE FOOT OR LESS FOR GULF WATERS TODAY. WAVE HEIGHTS INCREASE
TO 3-4 FEET ACROSS NORTHERN ATLANTIC WATERS THIS AFTERNOON. THE
ONLY EXCEPTION IS AROUND THUNDERSTORMS, WHICH COULD PROVIDE BRIEF
PERIODS OF HIGHER WAVE HEIGHTS AND GUSTY WINDS.
WITH THE PASSAGE OF ERIN TO THE EAST OF THE FLORIDA PENINSULA MID-
LATE WEEK, LOCAL ATLANTIC WATERS COULD SEE AN INCREASING NORTH-
NORTHEASTERLY SWELL DURING THIS TIME PERIOD.
BEACHES
ISSUED AT 1252 AM EDT TUE AUG 19 2025
INCREASING SWELL FROM ERIN IS EXPECTED AS EARLY AS TODAY, BUT
MORE LIKELY MID TO LATE WEEK. THIS WILL RESULT IN AN INCREASING
RIP CURRENT THREAT FOR THE ATLANTIC BEACHES AND POSSIBLE HIGH SURF
CONCERNS FOR PALM BEACH COUNTY. THERE IS A HIGH RISK FOR RIP
CURRENTS ACROSS PALM BEACH COUNTY BEACHES AND A MODERATE RISK FOR
BROWARD COUNTY BEACHES.
