AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE JACKSONVILLE FL
345 AM EDT TUE AUG 29 2000

CURRENTLY...WATER VAPOR IMAGERY SHOWING UPPER LOW ALONG THE NORTH CAROLINA
COAST MOVING SOUTH WITH A STRONG AREA OF PVA ROTATING AROUND IT
THROUGH OUR CWA. THIS HAS TRIGGERED A ROUND OF SCATTERED THUNDERSTORMS
WHICH HAS CONTINUED THROUGH MUCH OF THE NIGHT IN EXTREME SOUTH
GEORGIA AND NORTH FLORIDA. HAVE ISSUED SEVERAL SVR WARNINGS BUT NO
REPORTS OF SEVERE WX AS OF YET. THE MESO-ETA FROM LAST NIGHT APPEARS
TO HAVE NAILED THIS NOCTURNAL EVENT.

SHORT TERM...EXPECT CURRENT STORMS TO CONTINUE TO PROPAGATE SOUTH
AFFECTING OUR SOUTHERN CWA THROUGH THE EARLY MORNING HOURS. THE
STORMS IN OUR NORTHERN CWA WILL GRADUALLY COME TO AN END.

FORECAST...AVN CONTINUES TO SPIN UP AN INTENSE LOW OFF THE EAST
CENTRAL FLORIDA COAST AND MOVE IT NORTH...THEN NORTHWEST TOWARDS THE
SOUTH CAROLINA COAST. THE ETA HAS A MUCH WEAKER AND BROADER FEATURE.
IT DOES APPEAR THAT THE AVN MAY BE ON THE RIGHT TRACK IN DEVELOPING
A CIRCULATION...BUT IS DEEPENING IT TOO FAST. WILL THEREFORE HOLD
BACK ON INCREASING THE WINDS TO SCA LEVELS...BUT INCREASE THEM TO NO
HIGHER THEN 15 TO 20 KNOTS AND MAINLY FROM 20 TO 60 MILES OUT. ALSO
WITH UPPER LOW MOVING TO THE SOUTH...WILL HAVE A CONTINUTION OF
AREAS OF PVA ROTATING AROUND LOW THROUGH WEDNESDAY. HAVE LEANED
TOWARDS THE WETTER FAN GUIDANCE...ESP AT NIGHT.

THANKS FOR THE COORD KMLB...KCHS.
