Could be even worse than Katrina, because Katrina came in on the east side of New Orleans so the dirty side was over in Mississippi (which got leveled, way worse than anything Louisiana saw that day). It was the storm surge and levees failing that made Katrina so bad, and that danger is still there, but this time New Orleans also looks to be getting the dirty side of the hurricane.
This is really bad. My buddy in Baton Rouge decided a couple of days ago to stay home and ride it out, I hope he's okay. He's been through a few of these so he knows what he's in for, but you never know what weirdness can occur.
