#ATLflood and #ATLtraffic on Twitter are your best bets...
... for up-to-the-minute reports on blocked roads and what parts of town to avoid. As well as photos of the flooded areas.
And when the storm passes, send some karma to SpaceyG and DriveAFasterCar (she of #atlgas fame) for helping kickstart these hashtags. (We've also set up a feed for the #atlflood updates on our news page, clatl.com/news).
After the jump, an idea of just how bad the roads really are.
