...PATCHY DENSE FOG THROUGH THE OVERNIGHT HOURS...

SURFACE OBSERVATIONS AND WEBCAMS INDICATE LOCALLY DENSE FOG HAS
DEVELOPED IN EASTERN PENNSYLVANIA AND NORTHERN AND CENTRAL NEW
JERSEY. WITH LIGHT WINDS AND INCREASINGLY HUMID CONDITIONS, THE
FOG WILL LIKELY CONTINUE THROUGH THE OVERNIGHT HOURS.

IF DRIVING, EXPECT RAPID CHANGES IN VISIBILITY. SLOW DOWN, USE
LOW-BEAM HEADLIGHTS, AND MAINTAIN EXTRA DISTANCE FROM OTHER
VEHICLES.

...FLASH FLOOD WATCH REMAINS IN EFFECT FROM NOON EDT TODAY
THROUGH LATE TONIGHT...

THE FLASH FLOOD WATCH CONTINUES FOR

* NORTHEAST MARYLAND, DELAWARE, EASTERN AND SOUTHEASTERN
PENNSYLVANIA, AND CENTRAL AND SOUTHERN NEW JERSEY.

* FROM NOON EDT TODAY THROUGH LATE TONIGHT

* STRONG THUNDERSTORMS ARE EXPECTED TO DEVELOP AND MOVE THROUGH
THE REGION THIS AFTERNOON AND EVENING. THE ENVIRONMENT WILL BE
FAVORABLE FOR TORRENTIAL RAINFALL WITH THESE STORMS.
ADDITIONALLY, STORMS MAY BEGIN TO TRACK OVER THE SAME
LOCATIONS AS A VERY SLOW-MOVING FRONT ALLOWS FOR THE
REDEVELOPMENT OF STORMS IN SIMILAR LOCATIONS OVER TIME. THERE
IS POTENTIAL FOR ONE TO THREE INCHES OF RAIN IN A VERY SHORT
PERIOD OF TIME WHERE THE STRONGEST STORMS OCCUR.

* FLASH FLOODING IS POSSIBLE WHERE THE STRONGEST STORMS DEVELOP
AND PERSIST. FLOODING IN URBAN AND POOR-DRAINAGE AREAS IS
LIKELY IF TORRENTIAL DOWNPOURS OCCUR. RISES ON SMALL CREEKS
AND STREAMS ARE POSSIBLE AS WELL.

PRECAUTIONARY/PREPAREDNESS ACTIONS...

A FLASH FLOOD WATCH MEANS THAT THERE IS THE POTENTIAL FOR FLASH
FLOODING, WHICH CAN BE LIFE-THREATENING. HEAVY RAIN IS EXPECTED
TO OCCUR OVER A SHORT PERIOD OF TIME. RAPIDLY RISING FLOOD WATERS
MAY QUICKLY INUNDATE ROADWAYS AND AREAS OF POOR DRAINAGE. STREAMS
AND CREEKS COULD LEAVE THEIR BANKS, FLOODING NEARBY PROPERTIES.

PLEASE MONITOR THE FORECAST, ESPECIALLY IF YOU LIVE IN A LOCATION
THAT IS PRONE TO FLOODING. BE PREPARED TO TAKE ACTION IF A FLASH
FLOOD WARNING IS ISSUED FOR YOUR AREA.
