WEST CENTRAL AND SOUTHWEST FLORIDA FORECAST DISCUSSION NATIONAL WEATHER SERVICE TAMPA BAY AREA - RUSKIN FL 215 PM EDT TUE SEP 19 2000 CURRENTLY: 88D LOOP INDICATING SCT SHOWERS MOVING NW TOWARD THE AREA FROM SE FL. NORTHERN EDGE OF SHOWERS NOW INTO EXTREME SE POLK...SW TO S LEE COUNTY. THUS...EXPECT WDLY SCT/SCT SHOWERS AND TSTMS TO CONTINUE TO DEVELOP FROM S TO NORTH THIS AFTN/EVENING. WEST COAST SEABRZ SEEMS TO BE STRUGGLING TO DEVELOP...BUT MAY STILL GET A WEAK ONE RIGHT AT THE SHORE. LATEST FWC...WHICH IS USUALLY PRETTY GOOD AT CATCHING SEABRZ...NOW DOES NOT HAVE ONE TODAY. FCST: LOOKS LIKE THE TROPICS WILL NOT GIVE US A BREAK. STILL KEEPING A VERY CLOSE EYE ON WAVE OVER THE CENTRAL CARIBBEAN...AND ANOTHER EVEN BETTER ORGANIZED SYSTEM WEST OF THE YUCATAN. RECON IN BOTH SYSTEMS...AND WAITING TO HEAR FROM NHC FOR LATEST UPDATE. MODELS SEEM SIMILAR WITH HANDLING OF TROP WAVE IN CENT CARIBBEAN. GENERALLY THEY TRACK IT AS AN OPEN WAVE WNW TOWARD WESTERN TIP OF CUBA BY WED MORNING...THEN NNW INTO THE E GULF THROUGH EARLY FRI. AVN SEEMS MOST AGRESSIVE WITH CLOSING OFF SFC CIRC WITH THIS SYSTEM AS IT ENTERS THE E GULF. HOWEVER...EVEN THE AVN KEEPS IT WEST OF THE PENIN THROUGH LATE THURS. WILL KEEP THINGS SIMPLE FOR NOW WITH GENERALLY ESE FLOW THROUGH THURSDAY. FWC/FAN KEEP POPS IN THE 40-50% RANGE NEXT FEW DAYS... WHICH SEEMS REASONABLE. MAY GO LIKELY POPS OVER THE S WHERE BEST MOISTURE AND CLOSEST PROXIMITY TO WAVE WILL BE. SE GRADIENT SHOULD INCREASE EACH DAY AS WAVE APPROACHES. NOT EXPECTING WEST COAST SEABRZ THROUGH THE PERIOD...EXCEPT MAYBE WELL NORTH OF TPA ON WED. MAXES SHOULD BE NEAR TO SLIGHTLY ABV NORMAL WITH ESE FLOW AND LACK OF SEABRZ. EXTENDED: VERY DIFFICULT TO TELL NOT KNOWING HOW WAVE OVER THE CARIBBEAN WILL EVOLVE IN THE SHORT-TERM. SEEMS BEST COURSE OF ACTION WILL BE TO KEEP POPS IN THE GOOD CHC/LIKELY THROUGH FRI... THEN TAPER BACK TO MORE SCT BY WEEKEND. MARINE: WILL BE INTERSTING AS WINDS AND SEAS EXPECTED TO INCREASE WITH THE APPROACH OF THE WAVE FORM THE SE. WINDS WILL INCREASE FROM S TO N BEGINNING TONIGHT...BUT THINK SPEEDS WILL STAY BELOW SCEC TONIGHT. HOWEVER...WILL WORD FOR SCEzC CONDITIONS S OF TARPON FOR WED...THEN ALL AREAS BY WED NIGHT.
