Yeah it was a lot of rain. But the remnants of Tropical Storm Lee in 2011 were way worse as far as rainfall. That whole year was bad for the rain in Central PA. It was the only time in 11 years of being in our old house that we had water in the basement and a sewer backup from all the rain. It was a bad year for flooding and TS Lee killed the area as far as rain. I've got pics of couches (it hit day before trash day) and garbage flowing down the street we used to live on. The road was almost cresting the curb in places and our backyards had ponds.
I work in Hershey (not for Hershey) and the flooding was insane during Lee. I was not in the office but from seeing the pics from those that were as well as the news reports, you cannot imagine the damage. It truly was a 100 year flood event. The Swatara Creek had never been at those levels since we started keeping records. Dauphin County got some insane amount of rain (I want to say close to 20 inches) during that storm!
