The heaviest of the rainfall has already passed through our region, but flood warnings remain in effect as the storm will continue to pile on on to the nearly two inches of rain that already fell in parts of the Delaware Valley.
"The rain is tapering off," said NBC10 First Alert Chief Meteorologist Glenn "Hurricane" Schwartz. "It is going to end from west to east over the next six to eight hours."
Even though the worst of the storm has ended, the light rainfall will continue to drive totals up, which means flooding remains a concern, Schwartz added.
