NWS Tampa Bay, FL wrote its last area forecast discussion before this severe thunderstorm warning went out at Oct 7, 8:48 PM EDT, 9 hours 34 minutes earlier.
Area forecast discussion, Oct 7, 8:48 PM EDT, 9 hours 34 minutes before
AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE TAMPA BAY-RUSKIN, FL 848 PM EDT MON OCT 07 1996 AS TROPICAL STORM JOSEPHINE MOVES OFF TO THE NORTHEAST SHE WILL RAPIDLY LOOSE A LOT OF HER TROPICAL CHARACTERISTICS. ONE LOOK AT SAT PIX SHOW A VERY STRONG NEARLY STATIONARY CONVERGENT BAND OFF THE SOUTHWEST COAST. THIS BAND IS BEGINNING TO LOOK LIKE A BAROCLINIC LEAF. THIS WILL SLOWLY MOVE NORTH AS THE TROPICAL STORM MOVES NORTH...OR COULD JUST CHANGE ITS ORIENTATION. EITHER WAY THE CWA WILL SEE HEAVY FLOODING RAINS OVER NIGHT. I VERY...VERY...VERY...STRONGLY SUGGEST THAT MIAMI ISSUE A FLOOD WATCH FOR THE ENTIRE CWA FOR THE OVER NIGHT HOURS. LOW LEVEL SHEAR STILL LOOKS PRETTY GOOD FOR SVERE THUNDERSTORMS AND TORNADOS. ABOUT AN HOUR AGO WE LOADED OUR VAD WINDS INTO SHARP AND CAME UP WITH HELICITIES WELL OVER 200. REPORTS CONTINUE TO COME IN WITH WHAT IS BECOMING A SIGNIFICANT COASTAL FLOODING SITUATION. MORE ON THAT IN THE HLS.0 SOBIEN
