TROPICAL DEPRESSION ARLENE DISCUSSION NUMBER  15
NWS TPC/NATIONAL HURRICANE CENTER MIAMI FL
11 PM EDT SAT JUN 11 2005

ARLENE HAS CONTINUED TO WEAKEN AS THE CYCLONE MOVES FARTHER INLAND
OVER WEST-CENTRAL ALABAMA...EVEN THOUGH THE SATELLITE AND RADAR
SIGNATURES HAVE IMPROVED. IN FACT...ARLENE LOOKS BETTER NOW THAN IT
DID OVER WATER DURING MOST OF ITS LIFETIME. THE INITIAL INTENSITY
OF 25 KT IS BASED ON DOPPLER RADAR VELOCITY DATA AND SURROUNDING
SURFACE OBSERVATIONS. ADDITIONAL WEAKENING WILL OCCUR AND ARLENE
COULD EVEN DISSIPATE AS A TROPICAL CYCLONE BEFORE 24 HOURS.
HOWEVER...HEAVY RAINFALL AND POSSIBLE FLOODING WILL STILL BE A
SIGNIFICANT THREAT.

ARLENE IS FORECAST TO MOVE NORTH OR NORTH-NORTHEASTWARD WITH A
GRADUAL INCREASE IN FORWARD SPEED AS THE CYCLONE IS STEERED AROUND
THE WESTERN PERIPHERY OF A STRONG DEEP-LAYER RIDGE CENTERED NEAR
THE OUTER BANKS OF NORTH CAROLINA.

THIS IS THE FINAL ADVISORY ON ARLENE ISSUED BY THE NATIONAL
HURRICANE CENTER. FUTURE INFORMATION ON THIS SYSTEM CAN BE FOUND
IN PUBLIC ADVISORIES ISSUED BY THE HYDROMETEOROLOGICAL PREDICTION
CENTER...UNDER AWIPS HEADER TCPAT1 AND WMO HEADER WTNT31 KWNH...
BEGINNING AT 4 AM CDT...SUNDAY.
