The storms capable of producing damaging winds, large hail and isolated tornadoes appear to be over for now. But more rain is expected to fall in the comings days into already saturated soils and cause more flooding.

"The flood concern going forward looks to be from Virginia up into Southern New Jersey where rainfall amounts could be 4-8 inches over the coming days with localized amounts exceeding 10 inches," CNN meteorologist Michael Guy said.
