A LOW PRESSURE SYSTEM DEVELOPING IN THE GULF OF MEXICO IS FORECAST 
TO MOVE NORTHEAST AND PASS THROUGH DELAWARE AND NEW JERSEY ON 
WEDNESDAY. THIS LOW WILL TAP MOISTURE FROM BOTH THE GULF OF MEXICO 
AND THE ATLANTIC OCEAN AND HAVE THE POTENTIAL TO PRODUCE COPIOUS 
AMOUNTS OF RAINFALL OVERNIGHT TONIGHT INTO WEDNESDAY. THE HEAVIEST 
RAIN IS EXPECTED TO FALL IN ABOUT A TWELVE HOUR PERIOD FROM ABOUT 
MIDNIGHT TONIGHT TO ABOUT NOON ON WEDNESDAY ACROSS THE WATCH AREA. 
AMOUNTS ARE EXPECTED TO AVERAGE AROUND TWO INCHES WITH LOCAL AMOUNTS 
EXCEEDING THREE INCHES. THE HEAVY RAIN FROM LAST WEEK HAS LEFT SOME 
OF THE SMALLER STREAMS AND RIVERS IN THE WATCH AREA VULNERABLE TO 
ANY EXCESSIVE RAINFALL. THESE INCLUDE THE CHRISTINA RIVER IN 
DELAWARE...THE ASSUNPINK CREEK IN NEW JERSEY AND THE VALLEY CREEK IN 
PENNSYLVANIA. MOST MAINSTEM RIVERS ARE STILL RUNNING RELATIVELY LOW 
AND ARE NOT EXPECTED TO FLOOD WITH THE GIVEN STORM TOTALS.  

A FLOOD WATCH IS ISSUED WHEN SMALL STREAMS AND CREEKS ARE EXPECTED TO
RISE TO NEAR OR ABOVE BANKFULL LEVELS. THESE RISES ARE USUALLY DUE TO
EXCESSIVE RAINFALL OR HEAVY DOWNPOURS FALLING ON AN ALREADY SATURATED
GROUND. REMEMBER...A WATCH MEANS THAT FLOODING IS POSSIBLE BUT NOT
IMMINENT. PEOPLE IN THE WATCH AREA SHOULD KEEP ABREAST OF THE LATEST
WEATHER...AND PREPARE TO MOVE TO HIGHER GROUND SHOULD A WARNING BE 
ISSUED. THIS WATCH IS MORE FOR THE SMALLER...FLASHIER STREAMS IN THE 
WATCH AREA.

STAY TUNED TO NOAA WEATHER RADIO...YOUR LOCAL RADIO OR TELEVISION 
STATIONS...OR YOUR CABLE TELEVISION OUTLET FOR FURTHER DETAILS OR 
UPDATES. ADDITIONAL WEATHER INFORMATION CAN BE FOUND ON THE INTERNET 
AT WWW.ERH.NOAA.GOV/PHI IN SMALL LETTERS. EVEN WITHOUT STREAM 
FLOODING...HEAVY RAIN WEDNESDAY MORNING SHOULD MAKE THE MORNING 
COMMUTE MORE DIFFICULT THAN USUAL WITH PONDING OF WATER IN MANY POOR 
DRAINAGE LOCATIONS.
