HAZARDOUS WEATHER OUTLOOK
Issue Date: 927 PM EST THU DEC 17 2009
Expiration: 500 AM EST FRI DEC 18 2009
THIS HAZARDOUS WEATHER OUTLOOK IS FOR WEST CENTRAL AND SOUTHWEST
FLORIDA.
.DAY ONE...TONIGHT.
...THUNDERSTORM IMPACT...
A WARM FRONT ACROSS THE SOUTHERN PENINSULA EARLY TONIGHT WILL LIFT
SLOWLY NORTH INTO WEST CENTRAL FLORIDA OVERNIGHT AS AN AREA OF LOW
PRESSURE DEEPENS OVER THE CENTRAL GULF. INCREASING MOISTURE COMBINED
WITH THE WARM FRONT LIFTING NORTH WILL LEAD TO INCREASING CHANCES
FOR SHOWERS AND ISOLATED THUNDERSTORMS WITHIN THE DEVELOPING WARM
SECTOR THE REST OF THE NIGHT. ANY THUNDERSTORM THAT DEVELOPS WILL
BE CAPABLE OF PRODUCING LOCALLY HEAVY RAINS...OCCASIONAL LIGHTNING
STRIKES AND STRONG GUSTY WINDS.
...WIND AND SEA IMPACT...
WIND AND SEAS WILL CONTINUE TO INCREASE OVERNIGHT INTO FRIDAY OVER
ALL OF THE GULF WATERS AS AN AREA OF LOW PRESSURE APPROACHES FROM THE
WEST. WINDS AND SEAS ARE EXPECTED TO INCREASE TO AROUND 20 KNOTS NEAR
SHORE AND 20 TO 25 KNOTS OFFSHORE ALONG WITH SEAS BUILDING INTO THE
5 TO 7 FOOT RANGE. THESE INCREASING WINDS AND SEA WILL CREATE HAZARDOUS
BOATING CONDITIONS AND MARINERS...FISHERMEN...AND BOATING ENTHUSIASTS
MAY WANT TO POSTPONE TRIPS INTO THE GULF UNTIL CONDITIONS IMPROVE
LATER IN THE WEEKEND.
.DAYS TWO THROUGH SEVEN...FRIDAY THROUGH WEDNESDAY.
...THUNDERSTORM IMPACT...
AN INTENSIFYING LOW PRESSURE AREA WILL MOVE ACROSS THE NORTHERN FLORIDA
PENINSULA ON FRIDAY. A TRAILING COLD FRONT FROM THIS LOW WILL MOVE
THROUGH WEST CENTRAL AND SOUTHWEST FLORIDA DURING THE DAY. A SQUALL
LINE WILL LIKELY DEVELOP ALONG AND AHEAD OF THIS FRONT...IMPACTING
COASTAL LOCATIONS DURING THE MORNING HOURS...THEN SHIFTING EAST AND
SOUTH INTO INLAND AND SOUTHERN LOCATIONS DURING THE AFTERNOON AND
EARLY EVENING HOURS. CURRENT DATA SUGGESTS THE POSSIBILITY OF SEVERE
STORMS WITHIN THIS LINE WITH ORGANIZED STORMS PRODUCING DAMAGING WINDS
AND ISOLATED TORNADOES OR MARINE WATERSPOUTS. IN ADDITION LOCALLY HEAVY
RAINS AND DANGEROUS LIGHTNING WILL ACCOMPANY THE STORMS.
IN ADDITION TO THE SEVERE WEATHER STRONG AND GUSTY SOUTH TO SOUTHWEST
WINDS IN THE 20 TO 30 MILE PER HOUR RANGE WITH HIGHER GUSTS WILL LEAD
TO HAZARDOUS BOATING CONDITIONS ON AREA LAKES...AND OUTDOOR BOATING
ENTHUSIASTS MAY WISH TO POSTPONE LAKE RELATED ACTIVITIES UNTIL CONDITIONS
IMPROVE LATER ON SATURDAY.
...RIP CURRENT IMPACT...
STRONG SOUTH TO SOUTHWEST WINDS IN THE 20 TO 25 KNOT RANGE WILL HELP
TO BUILD SEAS OVER THE ADJACENT GULF WATERS. THESE INCREASING SEAS WILL
PRODUCE LARGE BREAKING WAVES AND AN INCREASED RISK FOR RIP CURRENTS ALONG
AREA BEACHES. RESIDENTS AND VISITORS SHOULD REMAIN OUT OF THE SURF.
...WIND AND SEA IMPACT...
STRONG SOUTH TO SOUTHWEST WINDS IN THE 20 TO 25 KNOT RANGE NEAR
SHORE AND AROUND 25 KNOTS WITH HIGHER GUSTS OFFSHORE ALONG WITH SEAS
BUILDING INTO THE 7 TO 9 FOOT RANGE WILL PRODUCE VERY HAZARDOUS BOATING
CONDITIONS ON THE GULF FRIDAY THROUGH EARLY SATURDAY. MARINERS...FISHERMEN
AND BOATING ENTHUSIASTS MAY WANT TO POSTPONE TRIPS INTO THE GULF UNTIL
CONDITIONS IMPROVE LATER IN THE WEEKEND.
...COASTAL FLOODING...
THE STRONG SOUTH TO SOUTHWEST WIND FLOW IN THE 20 TO 25 KNOT RANGE
WITH HIGHER GUSTS ALONG WITH THE BUILDING SEAS MAY PRODUCE SOME
MINOR COASTAL FLOODING AT TIMES OF HIGH TIDE ON FRIDAY FROM PASCO
COUNTY NORTH TO LEVY COUNTY...WITH LARGE BREAKING WAVE ACTION POSSIBLY
PRODUCING ADDITIONAL OVERWASH PROBLEMS IN SOME LOW LYING LOCATIONS.
AT THE CURRENT TIME TIDES ARE EXPECTED TO RUN SOME 2 TO 3 FEET ABOVE
NORMAL AT TIMES OF HIGH TIDE ON FRIDAY. COASTAL RESIDENTS SHOULD REVIEW
EVACUATION PLANS...AND BE READY TO MOVE AT A MOMENT`S NOTICE...SHOULD
ACTION BE REQUIRED.
.SPOTTER INFORMATION STATEMENT...
SPOTTERS SHOULD MONITOR THE WEATHER THE REST OF TONIGHT AND FORMAL
ACTIVATION MAY BE REQUIRED ON FRIDAY.
