Bye bye Big Easy
Mississippi 2005: What a direct hit looks like.
If you are in New Orleans you need to be somewhere else.
It's not as bad as you think. Katrina was Cat 4 IIRC. At most, Isaac will end up Cat 1 and it may even stay down to "tropical storm" level.
Also, it looks to me like this storm track will make Isaac bring rain to a big region which can use it. Like Iowa.

All the chaos from Katrina stemed from a storm that didn't really hit. This is going to be a TS or a 1 when it hits but it's coming in at an angle that will maximize the surge. This could be quite bad. If it was anywhere but NOLA...I'd shrug and be happy, as you are right that the rain is a welcome thing.

It just made landfall, as a cat 1, and it's expected to fade back down to TS almost immediately. The thing that worries me most, if the predictions are correct (and from this point on I think they'll be very good) is that the damned thing isn't moving very fast. Southern Louisiana is going to be under the strong effect of the storm for almost two days.
Every one of the three cyclones I've been through moved past really rapidly, with the strong winds only lasting a few hours. Having a storm last as long as this one will would be pretty strange, and of course it increases the chance of random damage just because it increases the number of die rolls.

OTH by tomorrow afternoon the below sea-level areas will be in the happy quadrant and the water will be blown AWAY from the lake, at which point they should be in the clear.
