Philly's mass transit is shutting down at midnight Saturday night until noon-ish Sunday. We're expecting a lot of rain and some flooding. Amtrack is shutting down at 5PM. New Jersey transit is suspending service at noon on Saturday.
I'm a former western new yorker and have dealt with ice storms and week long blizzards so I"m thinking the standard preparations should be fine. I've already got all the camping gear in the livingroom just in case.

We'll probably get an awful lot of rain saturday and sunday, but as long as we stay out of low lying areas we should be fine.
All of my friends are out partying tonight and will be doing the same all weekend long. Their first emergency supplies stop was the liquor store. I've already gassed up the car in case I get the call that somebody went and got themselves stuck somewhere without public transportation.
