Be prepared to take action in the event that flooding develops. Flash Flood Watch now in effect from 2 PM EDT this afternoon through Friday evening...  * From 2 PM EDT this afternoon through Friday evening * scattered showers and thunderstorms are expected to develop this   afternoon in the Delmarva and expand northward into southeastern   Pennsylvania and southern New Jersey through this evening. Some   of the thunderstorms will contain torrential rainfall and   result in a localized flash flood threat. Showers will become   more widespread late tonight into Friday and contain embedded   thunderstorms that could produce additional heavy rainfall over   the area. * The axis of heaviest rain still remains uncertain. However, the   potential for localized rainfall amounts of 2 or more inches in   one hour will bring the risk for flash flooding particularly in   urban areas. Isolated rainfall amounts of 4 inches or more are   possible during this event where storms move repeatedly over   the same area.
