Expiration: 700 PM EST THU DEC 17 2009
THIS HAZARDOUS WEATHER OUTLOOK IS FOR WEST CENTRAL AND SOUTHWEST
FLORIDA.
.DAY ONE...TODAY AND TONIGHT.
...THUNDERSTORM IMPACT...
SCATTERED SHOWERS TODAY WILL INCREASE IN COVERAGE AND BECOME MORE
WIDESPREAD TONIGHT. EMBEDDED THUNDERSTORMS ARE EXPECTED TO DEVELOP
BY LATE TONIGHT AS A WARM FRONT LIFTS NORTHWARD. WHILE THE
POTENTIAL FOR SEVERE WEATHER WILL BE GREATEST ON FRIDAY...A FEW
STRONG STORMS MAY OCCUR LATE TONIGHT OVER THE COASTAL WATERS WITH
THE MAIN CONCERN BEING STRONG GUSTY WINDS AND ISOLATED
WATERSPOUTS.
...WIND AND SEA IMPACT...
WINDS AND SEAS WILL REMAIN HIGH TODAY AS A TIGHT PRESSURE GRADIENT
CONTINUES BETWEEN HIGH PRESSURE TO THE NORTH AND A STATIONARY FRONT
TO THE SOUTH. A SMALL CRAFT ADVISORY REMAINS EFFECT FOR THE
OFFSHORE WATERS FROM ENGLEWOOD TO SUWANNEE RIVER. ELSEWHERE OVER
THE EASTERN GULF WATERS SMALL CRAFT SHOULD EXERCISE CAUTION.
MARINERS...ESPECIALLY THOSE THAT ARE INEXPERIENCED OR OPERATING
SMALLER VESSELS...MAY WISH TO POSTPONE TRIPS UNTIL CONDITIONS
IMPROVE.
.DAYS TWO THROUGH SEVEN...FRIDAY THROUGH WEDNESDAY.
...THUNDERSTORM IMPACT...
WARM HUMID AIR WILL RUSH NORTH FRIDAY AHEAD OF A LOW PRESSURE
SYSTEM AND ASSOCIATED COLD FRONT MOVING ACROSS THE GULF OF MEXICO.
THUNDERSTORMS ARE EXPECTED TO DEVELOP ALONG AND AHEAD OF THE COLD
FRONT AND PUSH INTO THE NATURE COAST FRIDAY MORNING AND THEN
SPREAD SOUTHWARD THROUGH THE REST OF THE AREA FRIDAY AFTERNOON.
THE POTENTIAL EXISTS FOR SOME STRONG OR MARGINALLY SEVERE STORMS
FRIDAY WHICH MAY PRODUCE STRONG WINDS...HEAVY RAINFALL AND DEADLY
CLOUD TO GROUND LIGHTNING. MODERATE SHEAR OUT AHEAD OF THE
BOUNDARY WILL INCREASE THE RISK FOR AN ISOLATED TORNADO. RESIDENTS
SHOULD CONTINUE TO MONITOR UPCOMING FORECASTS AND STATEMENTS
REGARDING THIS POTENTIALLY HAZARDOUS WEATHER SITUATION.
...COASTAL FLOOD IMPACT...
A STRONG SOUTHERLY WIND WILL DEVELOP ON FRIDAY AS A DEVELOPING
SURFACE LOW MOVES EAST ACROSS THE NORTHERN GULF. WINDS AND SEAS
WILL BE INCREASING THROUGH FRIDAY AFTERNOON PRODUCING A POTENTIAL
FOR MINOR COASTAL FLOODING ESPECIALLY ALONG SOUTH FACING SHORES OR
COASTAL AREAS AROUND LEVY COUNTY. CURRENT FORECAST TIDES ARE
RUNNING 1 TO 2 FEET ABOVE NORMAL VALUES ALONG THE WEST COAST OF
FLORIDA FROM LEE TO LEVY COUNTY FRIDAY AFTERNOON AND EVENING.
...RIP CURRENT IMPACT...
THERE WILL BE THE RISK OF RIP CURRENTS...STRONG UNDERTOWS...AND
LARGE BREAKING WAVES ALONG AREA BEACHES MUCH OF THE DAY FRIDAY AND
SATURDAY AS BREEZY WINDS AND ABOVE NORMAL TIDES AFFECT WEST
CENTRAL AND SOUTHWEST FLORIDA. ALWAYS SWIM NEAR A LIFEGUARD...OR
PLAN ON OTHER ACTIVITIES AWAY FROM THE BEACH
...WATERSPOUT IMPACT...
MODERATE LOW LEVEL SHEAR WILL ACCOMPANY THUNDERSTORMS MOVING
THROUGH THE GULF WATERS ON FRIDAY. THE RISK OF WATERSPOUTS CANNOT
BE RULED OUT AS THESE STORMS APPROACH THE SHORE. MARINERS SHOULD
CLOSELY MONITOR THE CHANGING WEATHER PATTERN.
...WIND AND SEA IMPACT...
WINDS AND SEAS ACROSS THE EASTERN GULF OF MEXICO WILL INCREASE IN
RESPONSE TO THE DEVELOPING STORM SYSTEM. AS WINDS INCREASE TO 20
TO 25 KNOTS IN THE OFF SHORE WATERS AND AROUND 20 KNOTS IN THE
NEAR SHORE...HAZARDOUS BOATING CONDITIONS WILL BE LIKELY ACROSS
THE GULF WATERS FRIDAY THROUGH SATURDAY NIGHT. THUNDERSTORMS
ASSOCIATED WITH THIS SYSTEM WILL CARRY THE POTENTIAL FOR STRONG
WINDS...HEAVY RAINFALL AND DEADLY CLOUD TO WATER LIGHTNING. CHOPPY
OR ROUGH CONDITIONS WILL BE LIKELY NEAR THUNDERSTORM ACTIVITY.
.SPOTTER INFORMATION STATEMENT...
SPOTTER ACTIVATION WILL NOT BE NEEDED TODAY.
