FLOOD WATCH
NATIONAL WEATHER SERVICE MOUNT HOLLY NJ
845 PM EST WED DEC 10 2003

...A FLOOD WATCH CONTINUES IN EFFECT FOR LATE TONIGHT THROUGH THURSDAY

THE NATIONAL WEATHER SERVICE HAS CONTINUED THE FLOOD WATCH FOR THE 
FOLLOWING COUNTIES...

  AND MONROE.

A LOW PRESSURE SYSTEM OVER THE OHIO VALLEY WILL CONTINUE TO 
INTENSIFY AS IT MOVES NORTHEAST, MOVING THROUGH THE SAINT LAWRENCE 
VALLEY LATER THURSDAY. A STRONG COLD FRONT WILL PASS THROUGH OUR AREA
EARLY THURSDAY MORNING. ON ITS WAY, THE SYSTEM WILL PICK UP
MOISTURE FROM THE GULF OF MEXICO AND THE ATLANTIC OCEAN. 

RAIN HAS OVERSPREAD THE REGION AND THE RAIN WILL BECOME HEAVY AS THE
NIGHT PROGRESSES. RAINFALL AMOUNTS OF ONE TO ONE AND ONE HALF INCHES
ARE FORECAST. ADDITIONALLY, UP TO ONE EXTRA INCH OF LIQUID IS POSSIBLE
DUE TO THE MELTING SNOW WHICH IS LIKELY TO MELT COMPLETELY.  

THE COMBINATION OF HEAVY RAIN AND SNOW MELT COULD CAUSE FLOODING 
ALONG SMALL STREAMS AND CREEKS AND IN AREAS OF POOR DRAINAGE LATE 
TONIGHT AND THURSDAY MORNING. STORM DRAINS MAY BE CLOGGED WITH SNOW 
OR LEAVES THAT WERE NOT COLLECTED BEFORE THE WEEKEND SNOW STORM. 
THIS COULD COMPOUND ANY FLOODING. MAIN STEM RIVER FLOODING IS NOT 
ANTICIPATED AT THIS TIME, BUT WILL BE MONITORED. AN ADDED
COMPLICATION MIGHT BE THE THURSDAY MORNING COMMUTE WITH OR WITHOUT
THE FLOODING. HEAVY RAIN MIGHT LINGER INTO THE START OF THE MORNING
COMMUTE...ESPECIALLY IN THE PHILADELPHIA NORTHERN SUBURBS AND CENTRAL
NEW JERSEY.

IN ADDITION TO THE FLOODING POTENTIAL...THE WARMER AIR PASSING OVER
THE SNOW COVER WILL EXPECTED AND ENHANCE THE FOG TONIGHT AND EARLY
THURSDAY MORNING. AREAS OF VERY DENSE FOG ARE LIKELY.
 
GIVE YOURSELF EXTRA TIME TO REACH YOUR DESTINATION THURSDAY MORNING.
 
A FLOOD WATCH MEANS THAT FLOODING OF STREAMS...CREEKS AND OTHER
DRAINAGE AREAS IS POSSIBLE WITHIN THE WATCH AREA. PEOPLE IN THE WATCH
AREA SHOULD KEEP AN EYE ON THE WEATHER AND BE PREPARED FOR IMMEDIATE
ACTION SHOULD HEAVY RAINS AND FLOODING OCCUR OR A FLOOD WARNING BE
ISSUED.

STAY TUNED TO NOAA WEATHER RADIO OR YOUR LOCAL TELEVISION OR RADIO
STATION. 

REMEMBER TO CHECK THAT YOUR NOAA WEATHER RADIO IS WORKING PROPERLY
