Jan 19, 1996
The combination of snowmelt from the previous week's two storms, unseasonably warm temperatures and an additional one to two inches of rain caused the flash flooding of almost every small stream and significant roadway flooding the afternoon and early evening hours on the 19th. Major flooding of the larger streams and rivers in Pennsylvania continued through the 21st. The flooding caused three deaths, all in Montgomery County, three injuries and about $50 million dollars in property damage.
