HURRICANE FLORENCE DISCUSSION NUMBER  36
NWS TPC/NATIONAL HURRICANE CENTER MIAMI FL   AL062006
1100 AM EDT TUE SEP 12 2006
 
FLORENCE APPEARS TO BE WELL INTO ITS EXTRATROPICAL TRANSITION.
SHOWER AND THUNDERSTORM ACTIVITY IS BECOMING CONFINED TO THE
NORTHERN SEMICIRCLE...ALONG THE PRE-EXISTING FRONTAL BOUNDARY
LOCATED OFF THE COAST OF EASTERN CANADA.  AS FLORENCE INTERACTS
WITH THIS FRONT...MOVES OVER COOLER WATER...AND CONTINUES TO DRAW
IN STABLE AIR...IT IS EXPECTED TO BECOME EXTRATROPICAL WITHIN 12
HOURS. 

DESPITE THE LESS IMPRESSIVE APPEARANCE IN SATELLITE IMAGERY THIS
MORNING...A QUIKSCAT PASS FROM 0902 UTC...DETECTED SOME HURRICANE-
FORCE WINDS ALONG THE WESTERN EDGE OF THE PASS. BASED ON THIS...THE
INTENSITY WILL REMAIN 65 KT FOR THIS ADVISORY.  DUE TO INTERACTIONS
WITH A TROUGH OVER EASTERN CANADA...AND THE ASSOCIATED BAROCLINIC
SOURCE OF ENERGY...LITTLE CHANGE IN STRENGTH IS EXPECTED AS
FLORENCE PASSES JUST SOUTHEAST OF NEWFOUNDLAND DURING THE NEXT 
DAY OR SO. 

FLORENCE IS MOVING JUST A LITTLE TO THE RIGHT OF THE PREVIOUS
FORECAST TRACK WITH AN ESTIMATED INITIAL MOTION OF 035/16. TRACK
GUIDANCE REMAINS IN GOOD AGREEMENT AND THE OFFICIAL FORECAST TRACK
IS CHANGED LITTLE FROM THE PREVIOUS ADVISORY.
 
LARGE NORTHEASTERLY SWELLS ARE EXPECTED TO PRODUCE ROUGH SURF AND
DANGEROUS RIP CURRENTS ALONG MOST OF THE EAST COAST OF THE UNITED
STATES AND THE BAHAMAS FOR ANOTHER FEW DAYS.
