Hurricane IGOR


ZCZC MIATCDAT1 ALL
TTAA00 KNHC DDHHMM
HURRICANE IGOR DISCUSSION NUMBER  54
NWS TPC/NATIONAL HURRICANE CENTER MIAMI FL   AL112010
1100 AM AST TUE SEP 21 2010
 
IGOR IS VERY CLOSE TO LOSING ALL ITS TROPICAL CHARACTERISTICS AND
WILL LIKELY BECOME FULLY EXTRATROPICAL BY THIS AFTERNOON.  THE
INITIAL INTENSITY IS BEING HELD AT 65 KT...ALTHOUGH IT IS POSSIBLE
THAT THE CYCLONE HAS STRENGTHENED OVER THE PAST FEW HOURS.  ASCAT
DATA SHOULD BE RECEIVED FROM NEAR THE HURRICANE SOON...AND A
RE-ASSESSMENT OF THE INTENSITY WILL BE MADE AT THAT TIME.  IGOR
COULD STILL GAIN SOME STRENGTH DURING THE NEXT 12-24 HOURS AS IT
MOVES NORTHWARD PAST NEWFOUNDLAND BUT THEN ALL THE MODELS SHOW
GRADUAL WEAKENING AS IT MOVES NEAR GREENLAND.  THE OFFICIAL
INTENSITY FORECAST IS A BLEND OF THE MODEL GUIDANCE...AND GUIDANCE
PROVIDED BY THE NOAA OCEAN PREDICTION CENTER.

IGOR IS MOVING RAPIDLY NORTHEASTWARD AT 40 KT.  MODEL GUIDANCE IS IN
GOOD AGREEMENT THAT IGOR WILL BE TURNING NORTHWARD DURING THE NEXT
24 HOURS AS IT SWINGS AROUND NEWFOUNDLAND AND MOVES THROUGH THE
DAVIS STRAITS.  THE EXTRATROPICAL CYCLONE IS EXPECTED TO SLOW DOWN
MARKEDLY FROM 36-96 HOURS AS IT INTERACTS AND POSSIBLY MERGES WITH
ANOTHER AREA OF LOW PRESSURE OFF THE NORTHEASTERN COAST OF QUEBEC. 
THE OFFICIAL FORECAST IS JUST A LITTLE FASTER THAN THE PREVIOUS ONE
AND REMAINS RELATIVELY NEAR THE MODEL CONSENSUS TVCN.
