The original forecast specified the area in and around New York, New Jersey, the Delmarva Peninsula, and New England.
The National Weather Service today issued a Flash Flood Watch for portions of Delaware, northeast Maryland, southern New Jersey, and southeast Pennsylvania.
Periods of rain is expected into Monday morning, some of which will be heavy at times. A total of 1 to 2 inches of rain is expected across much of the watch area. Some thunderstorms may occur through this evening mainly across Delmarva which could lead to locally higher amounts.
In addition to the above Watch, the NWS has issued a Flash Flood Warning for Delaware, Maryland, and a Flood Warning for West Virginia.
