I don't live there anymore, but where keswci and I used to live (Mount Pleasant) things are largely... wet. It's downtown Charleston that's really bad. I have a lot of friends still in the Lowcountry, and many have flooded backyards and other such calamities, but downtown Charleston was amazingly shut down for flooding. I've been down there for some bad flooding (drove a Jeep with 34" tires on 7" of total lift), but nothing like what they've got right now.
Just looked at NWS, and in all this mess Mount Pleasant leads the way in total rainfall... they've received over two FEET of rain since Thursday. Good grief.
