http://sigmund.biz/kat/I do not want to be an alarmist, but people who have the means to leave the greater New Orleans area need to do so. The infrastructure required to maintain a city is down. It could be a long time before it's back up. There will be too many people fighting for exceptionally scarce resources. It's one of those situations where you need A in order to fix B, but you can't do A until C happens and C can't happen until B is finished.
Right now, it's a matter of survival. There are 3 important aspects to surviving this: you need food/water/medicine, you need personal protection, and you need the means to conduct personal hygiene in such a way that you're not creating more of a problem than you're solving. For any media out there reading this, it would be very helpful for you to post guidelines for survivalist hygiene. This aspect is often the most overlooked. The possibility for disease is very high, especially in an area already infested with mosquitoes, roaches, flies, and rodents. Throw in dead bodies and unsatisfactory hygiene capabilities, overflowing sewage, etc. and you've got a recipe for an absolute disaster.
And then, there are looters, drug addicts who can't get their fix, and opportunists.
Things are going to get a lot worse before they get better. We are already instituting our own rules and guidelines for hygiene, personal behavior, etc. Effective use of time NOW is critical. Problems need to be dealt with before they exist, because they will exist and you don't want to have critical situations occur when you're dealing with something else.
The most important thing of all is to keep a clear head. When people freak out (women especially, sorry if you think that's sexist, but I'm telling you how it is), it adds an element of stress and wastes time and effort that could be directed elsewhere. Stay calm, use your head, set your priorities, act, evaluate your situation constantly, and remember that everyone is in this together. It's easy to want to step on everyone else to effect your own survival, but remember that every person who dies becomes a sanitation risk to you.
There it is. I am expecting the worst and preparing for it.
