Mid Atlantic Flooding

Throughout the Mid Atlantic region, rivers and creeks are on the rise, with flooding being reported in several states. Rainfall from Hurricane Irene, Tropical Storm Lee and other weather systems have pushed several rivers beyond flood stage.

In Maryland, several areas were experiencing flooding during early September:
On the Susquehanna, the Conowingo Dam floodgates are being opened due higher than normal flows caused by the remnants of Tropical Storm Lee. Flows have been on the rise since early Monday and are predicted to continue for the next several days.

The Avalon area of Patapsco Valley State Park in Elkridge is experiencing significant flooding along both the Baltimore County and Howard County sides of the river near U.S. Route 1.

Maryland Natural Resources Police (NRP) issued a warning on September 7 that boating and other recreational use of the Upper Potomac River, including its creeks and streams, should be avoided until September 9, 2011. The advisory will be updated if necessary.

The advisory was based on information received from the National Weather Service and the Maryland Emergency Management Agency (MEMA).

According to DNR, river levels are hazardous for recreational use on the main stem of the Upper Potomac River from Cumberland to Little Falls. According to DNR, hazardous conditions may also exist on tributaries of the Potomac River.

In Pennsylvania, flooding is extensive, with Harrisburg, Hershey and other areas being especially hard hit. The Susquehanna River was expected to crest in the coming days as rainfall continues.
