I’m going on a limb and disagreeing. It’ll be nasty and some creeks and roads will flood but I don’t think it‘ll be much worse than a severe 1 hour long storm that drops 2.5” rain.
A lot of rain will fall. But 6” isn’t devastating.
Edit: I don’t mean to downplay this event. I just don’t think it’ll be catastrophic-places will definitely flood.
We should do a rainfall contest. Include the following cities:
Harrisburg
Lancaster
York
Tamaqua
Williamsport
State College
Chambersburg
Clearfield
I thiiiink that covers the whole group basically without getting too lengthy.
