Tropical Storm BILL


ZCZC MIATCDAT3 ALL
TTAA00 KNHC DDHHMM
TROPICAL STORM BILL DISCUSSION NUMBER  36
NWS TPC/NATIONAL HURRICANE CENTER MIAMI FL   AL032009
500 AM AST MON AUG 24 2009
 
SATELLITE IMAGERY AS WELL AS RADAR AND SURFACE DATA FROM
NEWFOUNDLAND CANADA INDICATE THAT BILL HAS QUICKLY LOST TROPICAL
CHARACTERISTICS THIS MORNING.  THE CLOUD PATTERN HAS BECOME
INCREASING ASYMMETRIC WITH THE STRONGEST WINDS AND COLDEST CLOUD 
TOPS WELL REMOVED FROM THE CENTER. THE SYSTEM IS RAPIDLY MOVING
EAST-NORTHEASTWARD WITHIN A BAND OF STRONG UPPER-LEVEL WESTERLY
WINDS ASSOCIATED WITH THE SOUTHERN EXTENT OF A POLAR JET THAT IS
LOCATED JUST TO THE NORTH OF THE CYCLONE.  THE INITIAL INTENSITY
ESTIMATE IS 60 KT...WHICH IS BASED PRIMARILY ON BUOY...SHIP...AND
LAND OBSERVATIONS THAT RECORDED 50-56 KT WINDS DURING THE PAST 6
HOURS.  THE EXTRATROPICAL LOW IS FORECAST TO GRADUALLY WEAKEN
THROUGHOUT THE FORECAST PERIOD.
 
THE CYCLONE CONTINUES TO ACCELERATE EAST-NORTHWESTWARD WITH AN
INITIAL MOTION ESTIMATE OF 075/37.  BILL SHOULD CONTINUE TO MOVE
RAPIDLY EAST-NORTHEASTWARD ACROSS THE NORTH ATLANTIC DURING THE
NEXT DAY OR SO.  THE GLOBAL MODELS INDICATE THAT BILL WILL SLOW
DOWN AS IT INTERACTS WITH A LARGE EXTRATROPICAL LOW SOUTHWEST OF
ICELAND IN A COUPLE OF DAYS.  THE MODELS SUGGEST THAT THE
EXTRATROPICAL REMNANTS OF BILL WILL BE ABSORBED INTO THE LARGER LOW
SHORTLY THEREAFTER.  THE OFFICIAL FORECAST IS SIMILAR TO THE
PREVIOUS ADVISORY AND IS CLOSE TO THE MODEL CONSENSUS.

THIS WILL BE THE LAST NHC ADVISORY ON BILL.  ADDITIONAL INFORMATION
ON THIS SYSTEM CAN BE FOUND IN HIGH SEAS FORECASTS ISSUED BY THE
NATIONAL WEATHER SERVICE...UNDER AWIPS HEADER NFDHSFAT1 AND WMO
HEADER FZNT01 KWBC.
