SPECIAL WEATHER STATEMENT
Issue Date: 335 PM EST WED DEC 16 2009
Expiration: 400 AM EST THU DEC 17 2009
...POTENTIAL FOR SEVERE STORMS AND COASTAL HAZARDS ON FRIDAY...
AN AREA OF LOW PRESSURE IS EXPECTED TO DEVELOP OVER THE WESTERN
GULF OF MEXICO ON THURSDAY. THIS LOW IS THEN EXPECTED TO INTENSIFY
AS IT MOVES EAST ACROSS THE NORTHERN GULF COAST THURSDAY NIGHT AND
THEN ACROSS THE NORTHERN FLORIDA PENINSULA ON FRIDAY. AHEAD OF THE
LOW AN INCREASING MOIST SOUTHERLY WIND FLOW WILL DEVELOP OVER WEST
CENTRAL AND SOUTHWEST FLORIDA THURSDAY NIGHT AND FRIDAY. THIS
INCREASING SOUTHERLY FLOW WILL HELP TO BUILD SEAS OVER THE ADJACENT
GULF WATERS. THE BUILDING SEAS WILL GENERATE LARGE BREAKING WAVES
AND DANGEROUS RIP CURRENTS ALONG AND HIGH SURF ALONG AREA BEACHES
ON FRIDAY WITH ABOVE NORMAL TIDES POSSIBLY CAUSING SOME COASTAL
FLOODING AT TIMES OF HIGH TIDE ON FRIDAY.
THE STRONG SOUTHERLY WIND FLOW AND INCREASING SEAS WILL MAKE FOR
HAZARDOUS BOATING CONDITIONS OVER THE GULF WATERS AND INLAND
WATER WAYS...AND MARINERS...FISHERMEN...AND BOATING ENTHUSIASTS
MAY WANT TO POSTPONE TRIPS INTO THE GULF UNTIL CONDITIONS IMPROVE.
AS THE LOW PRESSURE AREA APPROACHES A MORE FAVORABLE ENVIRONMENT
FOR SEVERE STORMS WILL DEVELOP OVER WEST CENTRAL AND SOUTHWEST
FLORIDA LATE THURSDAY NIGHT INTO FRIDAY. AS THE LOW MOVES EAST
NORTHEAST ACROSS THE NORTHERN PENINSULA DURING THE DAY ON FRIDAY A
SQUALL LINE WILL LIKELY DEVELOP ALONG AND AHEAD OF A TRAILING COLD
FRONT OVER THE ADJACENT GULF WATERS EARLY FRIDAY MORNING WITH THE
LINE OF STORMS LIKELY TO AFFECT THE REGION FROM MID MORNING THROUGH
THE AFTERNOON AND EARLY EVENING HOURS.
AT THE CURRENT TIME SUFFICIENT LOW LEVEL MOISTURE COMBINED WITH
STRONG PREFRONTAL CONVERGENCE...SUFFICIENT DEEP LAYERED SHEAR AND
A STRONG LOW LEVEL JET MAY HELP TO PRODUCE ORGANIZED STORMS CONTAINING
DAMAGING WINDS AND POSSIBLE ISOLATED TORNADOES AND MARINE WATERSPOUTS.
IN ADDITION SOME LOCALLY HEAVY RAINFALL AND DEADLY LIGHTNING STRIKES
WILL ACCOMPANY THE STORMS AS THEY MOVE ACROSS THE REGION. IN THE WAKE
OF THE COLD FRONT A BRISK NORTHWESTERLY WIND FLOW WILL USHER IN A MUCH
COOLER AND DRIER AIR MASS WITH BELOW NORMAL TEMPERATURES EXPECTED ACROSS
THE REGION THROUGH THE UPCOMING WEEKEND...WITH SOME NEAR FREEZING
TEMPERATURES POSSIBLE OVER THE NATURE COAST BY SUNDAY NIGHT INTO MONDAY.
IN ADDITION TO THE COOLER TEMPERATURES THE BRISK NORTHWEST WIND FLOW
WILL KEEP SEA ELEVATED OVER THE ADJACENT GULF WATERS WITH HAZARDOUS
BOATING CONDITIONS CONTINUING.
ALL RESIDENTS AND VISITORS OF WEST CENTRAL AND SOUTHWEST FLORIDA
SHOULD REMAIN ALERT TO RAPIDLY CHANGING WEATHER CONDITIONS DURING
THURSDAY NIGHT INTO FRIDAY.
