TROPICAL DEPRESSION DENNIS DISCUSSION NUMBER  51
NATIONAL WEATHER SERVICE MIAMI FL
11 AM EDT SUN SEP 05 1999
 
DENNIS IS NOW WELL INLAND NORTHWEST OF RALEIGH NORTH CAROLINA.
ALTHOUGH SHORT TERM TRENDS INDICATE A MORE WESTERLY MOTION...THE 12
HOUR MOTION OF 305/11 IS USED FOR THIS PACKAGE. WATER VAPOR IMAGERY
SHOWS SOUTHWESTERLY FLOW ASSOCIATED WITH THE CENTRAL U.S. MID/UPPER
LEVEL TROUGH IS NOW AS FAR EAST AS ILLINOIS. DENNIS SHOULD TURN
NORTH WITHIN 12 TO 24 HOURS AND NORTHEAST THEREAFTER AS THIS FLOW
AFFECTS THE CYCLONE. NHC HURRICANE GUIDANCE IS IN GOOD AGREEMENT
WITH THIS SCENARIO.
 
THE ROANOKE WSR-88D SHOWS TROPICAL STORM FORCE WINDS ALOFT WELL
NORTH OF THE CENTER...WHILE THE RALEIGH WSR-88D DAYS NO TROPICAL
STORM FORCE WINDS REMAINING NEAR THE CENTER. THE MAXIMUM SUSTAINED
WINDS WILL REMAIN 30 KT...BUT THESE WILL LIKELY OCCUR ONLY IN A FEW
SQUALLS. GRADUAL WEAKENING AND TRANSFORMATION TO AN EXTRATROPICAL
SYSTEM IS EXPECTED BY 48 HOURS.

THIS IS THE LAST ADVISORY ISSUED ON DENNIS BY THE NATIONAL HURRICANE
CENTER. FUTURE INFORMATION WILL BE CONTAINED IN STORM SUMMARIES
ISSUED BY THE HYDROMETEOROLOGICAL PREDICTION CENTER IN WASHINGTON
D.C. UNDER AFOS HEADER NFDSCCNS5 AND WMO HEADER ACUS42 KWBC.
