What happened

The episode as NWS CTP wrote it up.

Heavy rain associated with a stalled frontal boundary, interacting with the remnants of a weak tropical system, caused flash flooding throughout central and eastern Pennsylvania from June 27 through June 28. While flash flooding ended on the 28th, flood waters continued in some locations until July 1st. In all, the governor signed a Declaration of Disaster Emergency for 46 Pennsylvania counties. 21 Counties were given federal disaster designation status, making them eligible for federal aid. Over 1200 water rescues were performed statewide. Hundreds of roads and bridges were closed during the event. At least 65 bridges were damaged, with an estimated 23 requiring total replacement. The American Red Cross opened 48 shelters statewide which housed more than 2500 people. More than 77,000 meals and snacks through 60 mobile feeding sites were also distributed by the American Red Cross. About 7800 residences were damaged, with between 275,000 and 300,000 voluntary evacuations orders being given.In Montour County, numerous roads and bridges were closed due to flood waters. Between 10 and 15 roads in the county sustained moderate damage, and 1 road was completely washed out. Water damage occurred in the sewage treatment plant and the school basement in Danville. 63 flooded basement were reported.Although the flash flooding ended early on the 28th in Montour County, flooding continued into the afternoon.
