Post-Tropical Cyclone FLORENCE


ZCZC MIATCDAT1 ALL
TTAA00 KNHC DDHHMM
 
POST-TROPICAL CYCLONE FLORENCE DISCUSSION NUMBER  11
NWS NATIONAL HURRICANE CENTER MIAMI FL       AL062012
1100 AM AST MON AUG 06 2012
 
ORGANIZED DEEP CONVECTION HAS BEEN ABSENT FOR OVER 12 HOURS
NOW...AND ALL THAT REMAINS OF FLORENCE IS AN EXPOSED SURFACE
CIRCULATION AND A SMALL CLUSTER OF THUNDERSTORMS LOCATED ABOUT 110
MILES WEST OF THE CENTER OF CIRCULATION.  CONSEQUENTLY...FLORENCE
IS ASSESSED AS A POST-TROPICAL REMNANT LOW AND THIS WILL BE THE LAST
ADVISORY ON THIS SYSTEM.  A SURROUNDING DRY/STABLE AIR MASS...COOL
SEA SURFACE TEMPERATURES...AND INCREASING SOUTHWESTERLY SHEAR
SHOULD LEAD TO DISSIPATION IN 5 DAYS OR LESS.
 
THE REMNANT LOW CONTINUES TO MOVE WESTWARD...BUT AT A SLIGHTLY
FASTER RATE OF FORWARD MOTION...275/13.  DURING THE NEXT COUPLE OF
DAYS...THE SYSTEM SHOULD TURN WEST-NORTHWESTWARD AND CONTINUE
TO INCREASE IN SPEED WITHIN THE LOW-LEVEL STEERING FLOW TO THE
SOUTH OF A SUBTROPICAL RIDGE. THE OFFICIAL NHC FORECAST IS
SIMILAR TO THE PREVIOUS PACKAGE AND IS BASED ON THE TVCA
MULTI-MODEL CONSENSUS.
