Major flooding affecting parts of the Northeast, Mid-Atlantic, US

Major flooding affecting parts of the Northeast, Mid-Atlantic, US

Heavy rainfall falling over the past couple of days caused major flooding in parts of the U.S. Northeast and Mid-Atlantic where rivers continue rising. In Pennsylvania's Lower Susquehanna Valley, authorities are describing the flooding as historic. A slow-moving low-pressure system combined with ample moisture will produce additional rainfall, some locally heavy from the Mid Atlantic to New England into Thursday, July 26, NWS warns. Flooding of low lying areas, streams, creeks, and rivers will be possible, the agency said.
Up to 420 mm (16 inches) of rainfall fell across the Mid-Atlantic and Northeast between July 21 and 26, causing major flash flooding in parts of the region. Numerous water rescues were reported and at least one city in Pennsylvania, the worst affected state, declared a disaster emergency.
One of the most heavily impacted creeks in the state and the region is Swatara Creek, east of Harrisburg, where two gauges reached major flood stage. Swatara flooded onto State Route 39 in Hershey, washing away parts of the roadway and forcing evacuations.
NWS State College said 'historic flooding is ongoing in Lower Susquehanna Valley,' adding that Swatara Creek at Hershey reached the second-highest level since records began in 1975.
"Swatara Creek at Hershey is forecast to remain in major flood level into the [July 26th] afternoon," the office said. "Max crest stage of 5.20 m (17.08 feet) is the 2nd highest level since records began in October 1975 (43 years)."
The creek is expected to fall below flood stage this weekend.
The Susquehanna River at Harrisburg is projected to crest around 5.79 m (19 feet) or just below moderate flood level late, Thursday, July 26.
Baltimore and Washington D.C. metro areas had many of their roads flooded Wednesday, July 25, TWC's Brian Donegan noted. 
Rock Creek in northwestern Washington D.C. and Sligo Creek in Takoma Park, Maryland, both surpassed flood stage Wednesday evening. 
Up to 305 mm (1 foot) of water was reported on Main Street in downtown Ellicott City, Maryland, on Wednesday evening. Three lanes of the Capital Beltway Inner Loop were blocked by high water in Montgomery County, Maryland. Some backyards and parking lots in the area were also inundated, and a water rescue was reported in Four Corners, Maryland.
At least two damaging tornadoes were reported; one in Lincolnia, Virginia and the other in Heidelberg Township, Pennsylvania. Both were rated EF-0.
