AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE MELBOURNE FL 940 AM EDT WED AUG 12 2004 .DISCUSSION... ...LOCAL ENHANCEMENT OF SEVERE WEATHER AND HEAVY RAIN THREATS DUE TO OUTER FRINGES OF BONNIE TODAY... ...TROPICAL CYCLONE CHARLEY IMPACTS EXPECTED FRIDAY... CURRENTLY...T.S. BONNIE HEADING FOR LANDFALL ALONG THE CENTRAL PANHANDLE. SATELLITE APPEARANCE OF THE SYSTEM IS A CLASSIC CASE OF INCREASING HYBRIDIZATION VIA BAROCLINIC ENHANCEMENT. TROUGH-LIKE APPENDAGE NOW EXTENDS SW FROM THE CENTER TO NEAR 42003 WITH CORRIDOR OF ENHANCED INFLOW SHOWING UP OFFSHORE THE FL WEST COAST. BROAD LOW LEVEL RIDGE AXIS LIES ACROSS THE CTRL PENIN FROM ABOUT KCOF TO JUST N OF KTPA. EXPECT LOCAL FORMATION OF ECSB FROM JUPITER NWD ALONG THE TREASURE COAST (PSBLY SOME OF BREVARD CO) THIS AFTN...THOUGH BUT PINNED RIGHT AT THE COAST. TWO AREAS TO BE MOST CONCERNED WITH FOR INCREASED POTENTIAL FOR ROTATING STORMS TODAY: 1) ACROSS THE WRN/NRN CWA CLOSEST TO THE TRACK OF BONNIE AND HENCE THE TRAILING CONVECTIVE BAND, WHERE MORE OF A SYNOPTIC SCALE INCREASE IN HELICITY PROFILE WILL OCCUR AND 2) ALONG THE ECSB WHERE LOCAL ENHANCEMENT OF HELICITY WILL TAKE PLACE. WILL BE INCREASING THESE THREAT LEVELS IN THE LOCAL HWO/G-HWO SUITE FOR THIS AFTN. HAVE ALSO DECIDED TO INCREASE POPS...AND WILL BE TWEAKING SKY/WINDS COVER GRIDS AS WELL. OTRW...FCST LOOKS TO BE IN GOOD SHAPE. ADDITIONAL ADJUSTMENT FOR FRI THROUGH SAT POSSIBLE IN ANOTHER UPDATE...BUT DEPENDENT ON 11 AM TPC PACKAGE. && MARINE...SHRS/TSTM ACTIVITY LINING UP NICELY ALONG THE WRN EDGE OF THE GULF STREAM. DATA BUOYS MEASURING STEADY 15KT S/SWRLY WINDS WITH SEAS RUNNING 3-4FT. BIGGEST IMMEDIATE CONCERN...HOWEVER...ARE THE SHORT PD WAVES GENERATED BY THE OFFSHORE WIND COMPONENT: BOTH BUOYS ARE INDICATING AVG PDS AOB 5SEC AND DOMINANT PDS BLO 4SEC...MAKING THE SEAS MUCH MORE CHOPPY THAN THE WAVE HEIGHTS ALONE INDICATE. WILL ADD CHOPPY WORDING TO THE OPEN ATLC WATERS. REMAINDER OF THE FCST WILL REMAIN UNCHANGED. && .MLB WATCHES/WARNINGS/ADVISORIES...NONE. && SHORT TERM...CRISTALDI LONG TERM...BRAGAW HAZARDS...SHARP

LUCIE- 1000 AM EDT THU AUG 12 2004 THIS HAZARDOUS WEATHER OUTLOOK IS FOR EAST CENTRAL FLORIDA. .DAY ONE...TORNADO THREAT INCREASING TODAY... ...THUNDERSTORM IMPACT... THE THREAT FOR TORNADOES IS INCREASING OVER THE FLORIDA PENINSULA. ATMOSPHERIC CONDITIONS ARE BECOMING MORE FAVORABLE TO SUPPORT A MODERATE THREAT OF TORNADOES ASSOCIATED WITH TROPICAL STORM BONNIE. MORNING SOUNDINGS HAVE REVEALED A VERY UNSTABLE ATMOSPHERE WITH CONDITIONS BECOMING EVEN MORE UNSTABLE GIVEN EXPECTED DAYTIME HEATING. ALSO...CONVECTION ASSOCIATED WITH BONNIE IS LOCATED MORE TO THE EAST OF THE CIRCULATION CENTER...EXPANDING THE THREAT AREA ACROSS EAST CENTRAL FLORIDA. IN SITUATIONS SUCH AS THIS... MULTIPLE OCCURRENCES OF WEAK SHORT LIVED TORNADOES BECOME MORE LIKELY. ALL RESIDENTS SHOULD LISTEN FOR POSSIBLE WATCHES...AND BE PREPARED TO ACT QUICKLY IF WARNINGS ARE ISSUED. POCKETS OF DRY AIR ALOFT WILL ALSO SUPPORT GOOD DOWNDRAFTS AND BOUNDARIES...RESULTING IN A MODERATE THREAT FOR DAMAGING WINDS ALSO. AS WITH ALL THUNDERSTORMS...LIGHTNING WILL BE THE FIRST HAZARD TO ARRIVE AND THE LAST TO LEAVE A LOCATION. ...FLOOD IMPACT... GIVEN THE AVAILABLE TROPICAL MOISTURE IN THE LOW LEVELS...SOME LOCALLY HEAVY RAIN WILL OCCUR TODAY. ISOLATED TOTALS COULD REACH ONE TO THREE INCHES. ...MARINE THUNDERSTORM GUST IMPACT... MARINE THUNDERSTORMS WILL BE MOVING NORTH NORTHEAST AT 15 KNOTS TODAY. AS THEY DO...THE STRONGER STORMS MAY RESULT IN MARINE WIND GUSTS OF 34 KNOTS. MARINERS SHOULD LISTEN FOR SPECIAL MARINE WARNINGS. ...WATERSPOUT IMPACT... ALONG WITH THE MODERATE THREAT FOR WEAK SHORT LIVED TORNADOES...A MODERATE THREAT EXISTS FOR WATERSPOUTS...ESPECIALLY WITHIN THE COASTAL ZONE...AND THE NORTH RIM OF LAKE OKEECHOBEE. ...RIP CURRENT IMPACT... WAVE CONDITIONS IN THE SURF ZONE WILL SUPPORT RIP CURRENTS OF AVERAGE INTENSITY...BUT IN THE PRESENCE OF A STRONG LONGSHORE CURRENT. SOUTH WINDS OF 10 TO 20 MPH ALONG THE IMMEDIATE COAST WILL PROMOTE THE GENERATION OF A STRONG LONGSHORE CURRENT WHICH WILL INCREASE THE CHANCE THAT OCEAN SWIMMERS WILL SUBSEQUENTLY ENCOUNTER A RIP CURRENT. ...WIND AND SEA IMPACT... SMALL CRAFT SHOULD EXERCISE CAUTION AND NOT VENTURE FAR FROM PORT. WINDS WILL BE SOUTH AT 15 TO 20 KNOTS WITH SEAS 3 TO 5 FEET...BECOMING 6 FEET BY TONIGHT. CONDITIONS WILL BE CHOPPY IN THE INTRACOASTALS...ESPECIALLY GIVEN THE LONG FETCH SOUTHERLY WINDS. MARINERS SHOULD REMAIN INFORMED OF THE LATEST EXPECTED MARINE CONDITIONS THROUGH SATURDAY GIVEN THE UNCERTAIN TRACK OF HURRICANE CHARLEY. .DAYS TWO THROUGH SEVEN...FRIDAY THROUGH NEXT THURSDAY. HURRICANE CHARLEY IS FORECAST TO APPROACH THE WEST CENTRAL FLORIDA COAST ON FRIDAY. CENTRAL FLORIDA RESIDENTS NEED TO REMAIN INFORMED TODAY REGARDING THE EXPECTED CONDITIONS TOMORROW ASSOCIATED WITH HURRICANE CHARLEY. WINDS TO TROPICAL STORM FORCE...LOCALLY HEAVY RAIN...AND SHORT LIVED TORNADOES ARE CURRENTLY THE MAIN CONCERNS FOR EAST CENTRAL FLORIDA. SINCE THE FORECAST WILL BE HIGHLY DEPENDENT UPON THE EXACT TRACK...AT THIS TIME...IT WOULD BE PRUDENT FOR LOCAL INTERESTS TO TAKE REASONABLE PRECAUTIONS SHOULD WATCHES OR WARNINGS BECOME NECESSARY. SOME SUGGESTED ACTIONS... FOLLOW THE ADVICE OF YOUR LOCAL EMERGENCY MANAGEMENT AGENCY. REVIEW THE HURRICANE ACTION PLAN FOR YOUR FAMILY OR BUSINESS. ENSURE THAT YOUR HURRICANE KIT IS WELL STOCKED AND UP TO DATE. INSPECT AND SECURE MOBILE HOME TIE DOWNS. DETERMINE WHETHER YOU NEED TO EVACUATE. REVIEW THE WORKING CONDITION OF EMERGENCY EQUIPMENT...SUCH AS FLASHLIGHTS AND BATTERY POWERED RADIOS. HIGHER TIDES...HEAVY SURF...LARGER BREAKERS AT INLETS AND RIP CURRENTS MAY DEVELOP WELL AHEAD OF THE TROPICAL CYCLONE. HEAVY RAINFALL MAY OCCUR...INTERESTS IN FLOOD PRONE AREAS SHOULD BE PREPARED TO TAKE PRECAUTIONS FOR THE SAFETY OF LIFE AND PROPERTY. TORNADOES CAN AND DO FORM WITH LITTLE OR NO NOTICE. REMAIN ALERT FOR DETERIORATING WEATHER CONDITIONS. ALL INTERESTS ARE URGED TO MONITOR NOAA WEATHER RADIO AND LOCAL MEDIA FOR THE PROGRESS OF THIS TROPICAL CYCLONE AND REMAIN ALERT FOR POSSIBLE WATCHES OR WARNINGS. .SPOTTER INFORMATION STATEMENT...
