Some areas that had barely dried out after Tropical Storm Lee were getting hit with flooding again as a low pressure system brought showers and heavy downpours to parts of Pennsylvania on Tuesday and Wednesday. The eastern half of the state was under flash flood watches and warnings.
Flooding was reported in Luzerne, Lackawanna and Wyoming Counties, areas that had been hit earlier this month by Lee. Flood warnings were also issued for parts of Columbia, Dauphin, Lancaster, Lebanon, Schuylkill, Snyder, Northumberland, Cumberland, Perry, York, Montour, Sullivan, Tioga, Lycoming and Union counties.
Charles Ross, hydrologist with the National Weather Service in State College, says the ground is still very saturated, and it doesn’t take a lot of rain to cause flooding. A low pressure system to the west brought moisture from the south with rain showers and embedded heavier thunderstorms.
Ross says August was already a wet month, and then we had Hurricane Irene and Tropical Storm Lee. He says that raised the risk for quick rises on streams, creeks and rivers in areas hit by heavy downpours. He says the rainfall amounts from this system are not anywhere near the level of Lee, but some areas were getting 3-6 inches.
Ross says the rain should start moving out Thursday and by the weekend, it will feel like fall.
