The episode as NWS BGM wrote it up.
Tropical moisture continued to stream northward into northeast Pennsylvania ahead of a frontal system which slowly moved westward into the eastern Great Lakes by Tuesday morning the 27th. Additional heavy rain fell Tuesday afternoon into Wednesday morning across Susquehanna County as the front moved back east and combined with a low pressure system moving up the eastern seaboard. Total rainfall for the three day period ending Wednesday was over 10 inches in many areas with 14.74 inches reported in Clinton Township. This batch of heavy rain sent most streams and creeks over their banks in what was the worst flash flooding this county has ever seen. The flash flooding lasted until Wednesday afternoon. Hardest hit areas were New Milford, Great Bend, Hallstead, Susquehanna, Lanesboro, Oakland and Little Meadows. One person was killed when he drove his car into a flooded roadway in Springville Township. Total damages to the county were at least 100 million dollars. 183 homes were damaged, 76 destroyed. There were 110 businesses damaged by the flood waters. 400 people were evacuated, with 100 people rescued. At least 50 roads were damaged by flood waters with 10 destroyed. At one point, 150 roads in the county were closed during the height of the flood. Thirty bridges were flooded countywide.
