As late as Sunday morning, we were being told 1 - 2”. Predictions didn’t get dire until late. It started furiously overnight, I guess around 4 am. It was mostly done by noon. Added a little up until 3 pm or 4 pm. In Annapolis, we got 10”, the bulk between 4 am and noon.
I live in Pittsburgh. In my mind, that is still “East Coast,” so when I hear of storms coming to the East Coast, I listen. Don’t know when I first heard of it, but it seems it has been a little while. I think it was before Sunday, but I could be wrong.
