SPECIAL WEATHER STATEMENT
NATIONAL WEATHER SERVICE TAMPA BAY RUSKIN FL
556 AM EST WED DEC 2 2009


LEVY-CITRUS-SUMTER-HERNANDO-PASCO-PINELLAS-HILLSBOROUGH-POLK-MANATEE-HARDEE-HIGHLANDS-SARASOTA-DE SOTO-CHARLOTTE-LEE-

INCLUDING THE CITIES OF...CEDAR KEY...CHIEFLAND...CRYSTAL RIVER...INVERNESS...BUSHNELL...THE VILLAGES...BROOKSVILLE...SPRING HILL...NEW PORT RICHEY...ZEPHYRHILLS...CLEARWATER...ST. PETERSBURG...BRANDON...TAMPA...LAKELAND...WINTER HAVEN...BRADENTON...WAUCHULA...SEBRING...AVON PARK...SARASOTA...VENICE...ARCADIA...PORT CHARLOTTE...PUNTA GORDA...CAPE CORAL...FORT MYERS

556 AM EST WED DEC 2 2009

...POTENTIAL FOR SEVERE STORMS AND COASTAL HAZARDS TODAY INTO THURSDAY...

DEVELOPING LOW PRESSURE OVER THE WESTERN GULF OF MEXICO WILL CONTINUE TO INTENSIFY AS IT MOVES ACROSS THE SOUTHEASTERN STATES TODAY. AHEAD OF THE LOW AN INCREASING MOIST SOUTHERLY WIND FLOW WILL DEVELOP OVER THE REGION. THIS INCREASING SOUTHERLY FLOW OVER THE ADJACENT GULF WATERS WILL HELP TO BUILD SEAS AND GENERATE LARGE BREAKING WAVES...DANGEROUS RIP CURRENTS AND HIGH SURF ALONG AREA BEACHES TODAY INTO THURSDAY.

TIDES ARE EXPECTED TO RUN ABOVE NORMAL ALONG THE ENTIRE WEST COAST OF FLORIDA...RANGING FROM AROUND ONE FOOT ABOVE NORMAL NEAR FORT MYERS TO 2 TO 3 FEET ABOVE NORMAL AROUND THE TAMPA BAY REGION... TO 3 TO 4 FEET ABOVE NORMAL FURTHER NORTH ALONG THE CITRUS AND LEVY COUNTY COASTS. THESE ABOVE NORMAL TIDES COULD CAUSE SOME COASTAL FLOODING AT TIMES OF HIGH TIDE TODAY AND TONIGHT...ESPECIALLY ALONG THE NATURE COAST. THEREFORE...A COASTAL FLOOD WATCH IS IN EFFECT FROM MANATEE COUNTY NORTHWARD THROUGH LEVY COUNTY.

THE STRONG SOUTHERLY WIND FLOW AND INCREASING SEAS WILL MAKE FOR HAZARDOUS BOATING CONDITIONS OVER THE ADJACENT GULF WATERS...AND MARINERS...FISHERMEN...AND BOATING ENTHUSIASTS MAY WANT TO POSTPONE TRIPS INTO THE GULF UNTIL CONDITIONS IMPROVE LATE IN THE WEEK.

AS THE LOW PRESSURE AREA LIFTS NORTHEAST INTO THE SOUTHEASTERN STATES THIS AFTERNOON A TRAILING COLD FRONT WILL APPROACH FROM THE WEST.
A MOIST AND UNSTABLE AIR MASS AHEAD OF THIS FRONT WILL SET THE STAGE FOR SHOWERS AND THUNDERSTORMS TO DEVELOP ALONG AND AHEAD OF THE BOUNDARY AS IT MOVES TOWARD WEST CENTRAL AND SOUTHWEST FLORIDA. CURRENT TIMING OF THIS FRONT WOULD BRING SHOWERS AND THUNDERSTORMS INTO THE NATURE COAST BY MID AFTERNOON...WITH THIS ACTIVITY SPREADING SOUTH INTO THE TAMPA BAY AREA DURING THE EARLY EVENING HOURS...AND THEN ACROSS SOUTHWEST FLORIDA BY MIDNIGHT.

AT THE CURRENT TIME SUFFICIENT LOW LEVEL MOISTURE COMBINED WITH STRONG PREFRONTAL CONVERGENCE AND INCREASING WIND SHEAR WITHIN THE ATMOSPHERE MAY SUPPORT SOME STRONG TO SEVERE STORMS AS THE FRONT MOVES SOUTH THROUGH THE REGION...ESPECIALLY FROM THE TAMPA BAY AREA NORTH THROUGH THE NATURE COAST. THE MAIN HAZARDS FROM THESE STORMS WILL BE DAMAGING WINDS AND ISOLATED TORNADOES AND WATERSPOUTS. IN ADDITION...LOCALLY HEAVY RAINFALL AND DEADLY
LIGHTNING STRIKES WILL ACCOMPANY THE STORMS.

ALL RESIDENTS AND VISITORS OF WEST CENTRAL AND SOUTHWEST FLORIDA SHOULD REMAIN ALERT TO RAPIDLY CHANGING WEATHER CONDITIONS TODAY AND TONIGHT.

Area Forecast Discussion
National Weather Service, Tampa Bay, Ruskin, Fla.
1:28 p.m. EST. Thursday, December 3, 2009


Short Term (Tonight-Saturday)...SW Flow will remain in place aloft through the period with a series of upper disturbances moving over the area in the flow. The surface cold front will gradually stall across south Florida later this afternoon with winds becoming more N/NE across the area overnight. Some overrunning showers will be possible with this set-up with the best rain chances across the southern zones. Low pressure will then develop over the Gulf waters along the boundary and lift it slowly northward Friday bringing likely rain chances across the area Friday night and early Saturday. The Gulf low will then move across the state into the Atlantic with high rain chances continuing across the area. The attendant cold front will then push through the area Saturday afternoon allowing for clearing to begin across the north as High pressure begins to build behind the front. With deep moisture and energy in place from the system...Expect that rainfall totals across the area will total 2-4 inches with localized amounts of 4-6 inches across the central zones. Will issue a Flood Watch for this as recent rains and poor soil absorption may cause flooding issues especially for area rivers.

Long Term (Saturday night through Thursday)...Cold front to continue SE push out of the area but upper level flow continues from the SW with surface High pressure building North of the area bringing slightly cooler and drier air mass that will be filtering into the region as temperatures drop slightly below normal.

Atmosphere quickly moderates as low level flow veers easterly and abundant mid to upper level gulf moisture advects back over the area. Upper short wave to generate weak surface feature to move through the region for a slight chance of showers late Monday into Tuesday as temperatures climb and remain above normal. Deep upper trof continues down the central U.S. mid week with deepening storm system moving through the eastern U.S. while attendant cold front sweeps into the area late in the period. Models vary with timing of front so will hold with slight chance POPS through mid week.
