FLOOD WARNING
NATIONAL WEATHER SERVICE PHILADELPHIA/MT HOLLY NJ
1000 AM EST FRI JAN 19 1996

THE NATIONAL WEATHER SERVICE IN PHILADELPHIA/MT HOLLY HAS ISSUED A
FLOOD WARNING FOR SMALL STREAMS...URBAN AND POOR DRAINAGE AREAS
EFFECTIVE UNTIL 700 PM EST FOR PEOPLE IN THE FOLLOWING COUNTIES...

IN  PENNSYLVANIA

   ...CARBON...MONROE...BERKS...LEHIGH...NORTHAMPTON...CHESTER...
   ...MONTGOMERY...BUCKS...DELAWARE...PHILADELPHIA...

IN NEW JERSEY

   ...SUSSEX...WARREN...MORRIS...HUNTERDON...SOMERSET...MIDDLESEX...
   ...MERCER...MONMOUTH...BURLINGTON...CAMDEN...GLOUCESTER...SALEM...

IN DELAWARE

   ...NEW CASTLE...

IN MARYLAND

   ...CECIL...

THE COMBINATION OF STRONG SOUTH WINDS AND MILD TEMPERATURES OVERNIGHT HAS
MELTED A SIGNIFICANT AMOUNT OF THE SNOWPACK.  THIS MELTING OF SNOW AND
SOME LIGHT RAIN SHOWERS AHEAD OF AN APPROACHING COLD FRONT HAVE ALREADY
CAUSED MANY SMALL STREAMS IN THE AREA TO APPROACH OR EXCEED BANK FULL.

THE COLD FRONT...NOW MOVING RAPIDLY EASTWARD THROUGH CENTRAL PENNSYLVANIA
...WILL BRING ADDITIONAL HEAVY RAINS INTO THE AREA.  THE BAND OF HEAVIER
RAIN WILL BE MOVING EAST INTO THE POCONOS...LEHIGH VALLEY...SOUTHEAST
PENNSYLVANIA...EXTREME NORTHEAST MARYLAND...AND NORTHERN DELAWARE BETWEEN
1000 AM AND NOON.  THE HEAVY RAIN WILL CONTINUE TO SPREAD ACROSS NEW
JERSEY BETWEEN NOON AND 200 PM THIS AFTERNOON.  THERE WILL BE A TWO TO
THREE HOUR PERIOD OF MODERATE TO HEAVY RAIN OVER THESE AREAS...WHICH WILL
LIKELY PRODUCE RAINFALL TOTALS FROM ONE TO TWO INCHES.  

THIS ADDITIONAL RAIN WILL AGGRAVATE THE PROBLEMS ALREADY CAUSED BY THE
MELTING SNOW...AND WILL LIKELY CAUSE MANY SMALL STREAMS AND TRIBUTARIES
TO OVERFLOW THEIR BANKS.  SPECIFIC FORECASTS FOR TRIBUTARIES AND THEIR
STAGES WILL BE ISSUED AS NECESSARY.

ALSO...THERE WILL BE PONDING OF WATER ON MANY STREETS AND ROADWAYS...
ESPECIALLY WHERE STORM DRAINS ARE STILL BLOCKED BY SNOW AND ICE. 

STRONG SOUTH WINDS AHEAD OF THE COLD FRONT HAVE PUSHED WATER UP THE
DELAWARE BAY AND INTO TIDAL PORTIONS OF THE DELAWARE RIVER AND ITS
TRIBUTARIES.  THIS WILL RESULT IN AN ABNORMALLY HIGH TIDE AROUND NOON
TODAY...TWO OR MORE FEET ABOVE NORMAL...ALONG THE LOWER DELAWARE.
FLOODING IS POSSIBLE IN LOW LYING AREAS AS FAR NORTH AS THE RANCOCAS
CREEK IN BURLINGTON COUNTY.

RAIN WILL END FROM WEST TO EAST THIS AFTERNOON...FOLLOWED BY MUCH COLDER
AIR AND PERHAPS SOME SNOW FLURRIES. ANY STANDING WATER LEFT ON ROADWAYS
WILL FREEZE CAUSING ADDITIONAL DRIVING HAZARDS.

DO NOT DRIVE YOUR VEHICLE INTO AREAS WHERE THE WATER COVERS THE
ROADWAY.  THE WATER DEPTH MAY BE TOO GREAT TO ALLOW YOUR CAR TO
CROSS SAFELY.  VEHICLES CAUGHT IN RISING WATER SHOULD BE
ABANDONED QUICKLY.  MOVE TO HIGHER GROUND.
