DISCUSSION AND 48-HOUR OUTLOOK
------------------------------
AT 500 AM EDT...0900 UTC...THE CENTER OF POST-TROPICAL CYCLONE
BILL WAS LOCATED NEAR LATITUDE 39.6 NORTH...AND LONGITUDE 76.0
WEST. WHILE POST-TROPICAL CYCLONE BILL STILL HAS SOME CYCLONIC
CIRCULATION...IT HAS SIGNIFICANTLY WEAKENED AS ONLY A RAGGED AREA
OF LOW PRESSURE REMAINS ACROSS NORTHEASTERN MARYLAND. RADAR
IMAGERY SHOWS CONVECTION TO THE SOUTH OF THE LOW BUT IT IS MUCH
LESS ORGANIZED THAN IT HAS PREVIOUSLY BEEN DURING THE PAST FEW
DAYS.  SURFACE OBSERVATIONS SHOW VERY WEAK WIND FIELDS IN PLACE
WITH 5 TO 10 KNOTS ACCOMPANIED BY SLIGHTLY HIGHER GUSTS. OUTER
RAINBANDS CONTINUE TO MOVE AHEAD OF THE CENTER INTO NORTHEASTERN
PENNSYLVANIA...NEW JERSEY...AND INTO SOUTHEASTERN NEW YORK AND
LOWER COASTAL NEW ENGLAND. THE REMNANTS OF BILL ARE EXPECTED TO
CONTINUE MOVING EAST-NORTHEASTWARD INTO THE FAR EASTERN PART OF
THE UPPER MID-ATLANTIC AND LOWER NEW ENGLAND EARLY THIS MORNING
AND WILL TRACK ACROSS THE NORTHEAST COASTLINE LATER IN THE
MORNING. THE REMNANTS OF BILL COULD BRIEFLY RESTRENGTHEN AS IT
BECOMES EXTRATROPICAL OVER THE NORTHERN MID-ATLANTIC AND SOUTHERN
NEW ENGLAND COAST.

MAXIMUM SUSTAINED WINDS ARE NEAR 25 MPH...40 KM/H...WITH HIGHER
GUSTS.

MINIMUM CENTRAL PRESSURE IS 1005 MB...29.68 INCHES.


HAZARDS
-------
RAINFALL...THE REMNANTS OF BILL IS EXPECTED TO PRODUCE RAINFALL
TOTALS OF 1 TO 2 INCHES OF RAIN ACROSS EASTERN SECTIONS OF THE
UPPER MID-ATLANTIC AND UP INTO COASTAL NEW ENGLAND.  THESE RAINS

FLOODING...PARTICULARLY IN REGIONS WHICH ARE ALREADY SATURATED
FROM PREVIOUS HEAVY RAINFALL.
