The remnants of Tropical Storm Lee have made their way slowly from the Gulf of Mexico to the northeastern United States, bringing a storm with a slow-moving heavy rain. There is widespread flooding in the Susquehanna River basin and flash floods across the area. The Weather Underground's Jeff Masters has commentary on the storm from the morning of September 8, 2011, saying
An extreme rainfall event unprecedented in recorded history has hit the Binghamton, New York area, where 7.49" fell yesterday. This is the second year in a row Binghamton has recorded a 1-in-100 year rain event; their previous all-time record was set last September, when 4.68" fell on Sep 30 - Oct. 1, 2010. Records go back to 1890 in the city. The skies have now cleared in Binghamton, with this morning's rain bringing the city's total rainfall for the 40-hour event to 9.02". However, another large region of rain lies just to the south in Pennsylvania, and all of the rivers in the surrounding region are in major or record flood. The Susquehanna River at Binghamton is at 25', its highest level since records began in 1847, and is expected to overtop the flood walls protecting the city this afternoon. In Hershey, Pennsylvania, Swatara Creek is 18' over flood stage, and more than 8' above its record flood crest. Widespread flash flooding is occurring across the entire area, and over 10,000 people have been evacuated from their homes.
For current information, tune in to local news. Among the sources I have found that are broadcasting emergency flood coverage are WNEP TV-16 Scranton, the Times Leader in Wilkes-Barre, the Times Tribune, and WBNG-TV 12 Binghamton.
Emergency services channels can be tuned in via Radio Reference for Binghamton, Broome, Tioga, and Susquehanna Counties; Lycoming County Public Safety; Bradford County Fire; Schoharie County Public Safety; and other systems.
