The Flash Flood Watch has been extended across the Lower Susquehanna River Vally by the National Weather Service. It now expires at 12 A.M. Wednesday. Periods of heavy showers and thunderstorms are possible across the region through this evening. This may lead to localized flooding of poor drainage roads, small creeks, and small streams. Those areas normally prone to flooding are most at risk. Stay with Fox43 WPMT for more updates as they become available.
