CONCERNING...SEVERE THUNDERSTORM WATCH 551...

VALID 212208Z - 212315Z

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.
