STORM SUMMARY NUMBER 57 FOR THE REMNANTS OF "DENNIS"
NATIONAL CENTERS FOR ENVIRONMENTAL PREDICTION
HYDROMETEOROLOGICAL PREDICTION CENTER...NWS...CAMP SPRINGS MD
700 PM EDT MON SEP 06 1999

AT 700 PM EDT...THE CENTER OF THE LOW THAT WAS ONCE CALLED DENNIS WAS
LOCATED JUST SOUTHWEST OF CHARLOTTESVILLE, VIRGINIA.  MAXIMUM
SUSTAINED WINDS OF ONLY 10 MPH WERE OBSERVED IN ASSOCIATION WITH
THE REMNANTS OF DENNIS...ALTHOUGH SOME HIGHER GUSTS WERE STILL
LIKELY IN SOME OF THE HIGHER ELEVATIONS OF WESTERN VIRGINIA.  THE
MINIMUM CENTRAL PRESSURE REMAINS 1008 MB...29.77 INCHES...AND DENNIS
CONTINUES MOVING NORTH-NORTHEAST AT 12 MPH.  FURTHER ACCELERATION
OF THE LOW IS EXPECTED AS DENNIS GETS CAUGHT UP IN SOME STRONGER
FLOW AHEAD OF A COLD FRONT NOW LOCATED IN THE OHIO VALLEY. 

HEAVIER BANDS OF THUNDERSTORMS ON THE PERIPHERY OF THE REMNANTS
OF DENNIS HAVE RESULTED IN FLASH FLOOD WARNINGS BEING ISSUED INTO
THE EARLY MONDAY EVENING HOURS FOR PARTS OF SOUTHERN
PENNSYLVANIA AND NORTHERN NORTH CAROLINA.  SOME OF THESE
THUNDERSTORMS THAT ARE OCCURRING EARLY MONDAY EVENING ARE
PRODUCING ADDITIONAL 2 TO 3 INCH RAINFALL AMOUNTS IN EDGECOMBE
COUNTY, NORTH CAROLINA, WHERE 6 TO 7 INCHES OF RAIN HAD ALREADY
OCCURRED DUE TO DENNIS.  

AS THE LOW CONTINUES TO SLOWLY WEAKEN...THE MAIN THREAT FROM THE
SYSTEM THE NEXT 24 HOURS WILL BE FROM LOCALLY HEAVY
RAINFALL...WHICH HAS RESULTED IN THE ISSUANCE OF NUMEROUS FLASH
FLOOD WATCHES.  DUE TO THE FORECASTED NORTH-NORTHEAST
MOVEMENT...THESE FLASH FLOOD WATCHES HAVE BEEN POSTED THROUGH
TUESDAY FOR THE EASTERN SHORE OF MARYLAND...DELAWARE...MOST OF
EASTERN AND CENTRAL PENNSYLVANIA...NEW JERSEY...PORTIONS OF
SOUTHERN AND EASTERN NEW YORK STATE...LONG ISLAND AND CONNECTICUT. 
RAINFALL WITHIN THESE WATCH AREAS COULD EASILY TOTAL 2-4
INCHES...WITH SOME AMOUNTS GREATER THAN 5 INCHES POSSIBLE IN SOME OF
THE HIGHER TERRAIN FROM PENNSYLVANIA INTO NEW YORK STATE AS SOME
ADDITIONAL ATLANTIC MOISTURE GETS PULLED INTO THESE AREAS.  

NO SEVERE WEATHER WATCHES (SEVERE THUNDERSTORM/TORNADO) ARE IN
EFFECT AT THIS TIME...AND ANY FUTURE SEVERE POTENTIAL LOOKS FAIRLY
SLIM THROUGH TUESDAY AS THE WIND FIELDS CONTINUE TO WEAKEN WITH
THIS SYSTEM.

FOR PUBLIC DISSEMINATION....THE WMO HEADER FOR THIS PRODUCT IS ACUS45
KWBC.

THE NEXT STORM SUMMARY ON DENNIS WILL ISSUED AT 100 AM EDT.
