   THE SEVERE WEATHER THREAT FOR SEVERE THUNDERSTORM WATCH 551
   CONTINUES.
   
   PRIMARY REMAINING SEVERE THREAT APPEARS TO BE CONFINED TO NORTH OF A
   TAMPA TO CAP CANAVERAL LINE FOR THE NEXT 1-2 HOURS.
   
   NUMEROUS OUTFLOW MERGERS AND THUNDERSTORMS HAVE OVERTURNED MUCH OF
   THE SRN HALF OF THE FL PENINSULA. STRONGEST STORMS REMAIN OVER THE
   NRN FL PENINSULA...BUT THESE ARE ALSO IN THE PROCESS OF MERGING. IT
   APPEARS THAT BEYOND 23Z MOST OF THE REST OF THE NRN FL PENINSULA
   WILL HAVE BEEN STABILIZED BY THE ONGOING STORMS...SUGGESTING THE
   SEVERE THREAT WILL LIKELY END ONE TO TWO HOURS BEFORE THE WATCH
   EXPIRATION TIME OF 01Z.
