Tropical Storm NICHOLAS


ZCZC MIATCDAT4 ALL
TTAA00 KNHC DDHHMM
TROPICAL STORM NICHOLAS DISCUSSION NUMBER  33
NWS TPC/NATIONAL HURRICANE CENTER MIAMI FL
ISSUED BY HYDROMETEOROLOGICAL PREDICTION CENTER CAMP SPRINGS MD
5 PM EDT TUE OCT 21 2003
 
THE CENTER OF NICHOLAS CONTINUES TO BE WELL EXPOSED WITH MOST OF THE
CONVECTION CONCENTRATED TO THE EAST.  WHILE AVAILABLE 18Z SATELLITE
LOCATION ESTIMATES ARE ALMOST IDENTICAL...DVORAK INTENSITY DROPPED
SLIGHTLY SO THE INITIAL INTENSITY IS REDUCED TO 40 KTS WITH A
MINIMUM CENTRAL PRESSURE OF 1005 MB.

THE INITIAL MOTION IS ESTIMATED AT 300/08.  WE EXPECT NICHOLAS TO
BEGIN ITS CURVE AROUND THE PERIPHERY OF THE MID-ATLANTIC UPPER
RIDGE AND EVENTUALLY ACCELERATE AS IT BECOMES INFLUENCED BY THE
TROF MOVING OFF THE EAST COAST OF THE UNITED STATES.  THERE HAS
BEEN LITTLE CHANGE IN THE NHC MODEL GUIDANCE FROM THE PREVIOUS
PACKAGE AND THUS THE OFFICIAL TRACK IS AGAIN A CONSENSUS.  EXPECT
THE WIND FIELD TO GRADUALLY EXPAND AFTER 24 HRS AS THE TRANSITION
TO A LARGE EXTRATROPICAL GALE BEGINS.
