   VALID 091531Z - 091630Z
   
   THE SEVERE WEATHER THREAT FOR TORNADO WATCH 46...47...CONTINUES.
   
   THREATS FOR BOTH TORNADOES AND DAMAGING WINDS CONTINUE FROM COASTAL
   PARTS OF FAR SERN LA AND MS INTO SWRN-SRN AL...WITH ACTIVITY QUICKLY
   APPROACHING THE WRN FL PANHANDLE.  IN ADDITION TO THE SEVERE WEATHER
   THREAT...HEAVY RAINFALL RATES /EXCEEDING 1 INCH PER HOUR/ CAN BE
   EXPECTED ALONG WITH TRAINING OF STORMS ACROSS THE COASTAL AREA OF
   THE CENTRAL GULF COAST.  THIS WILL BE ESPECIALLY LIKELY WHERE THE
   LINE OF TSTMS BECOMES ORIENTED E-W.
   
   REGIONAL RADAR IMAGERY INDICATED THE WELL DEFINED QLCS STRUCTURE
   EXTENDING FROM SOUTH CENTRAL AL SWWD TO COASTAL AREAS OF MS AND FAR
   SERN LA...WITH THE LINE MOVING EWD AT 40 KT.  AREA VWP INDICATED
   VERY STRONG LOW LEVEL SHEAR /0-1 KM SRH 300-400+ M2 PER S2/...WHILE
   EFFECTIVE BULK SHEAR /EXCEEDING 50 KT/ ALONG THE QLCS SUPPORTS BOTH
   THE LINEAR STRUCTURE AND EMBEDDED SUPERCELLS.  OBJECTIVE ANALYSES
   SHOWED THE AIR MASS DOWNSTREAM CONTINUES TO MOISTEN/DESTABILIZE
   ESPECIALLY ACROSS THE FL PANHANDLE AND INTO FAR SERN AL.  THESE
   FACTORS SUPPORT A CONTINUED THREAT FOR BOTH TORNADOES...SOME STRONG
   AND LONG-LIVED...AND DAMAGING WINDS WITH BOWING STRUCTURES.
