Well, I wouldn't.
I live in Tampa Bay, and if there is potential for the kind of hurricane that was headed toward NO, I'd hope that people would evacuate every time.
If it doesn't hit head on, praise the Lord.
If it does, I've at least followed the guidance of those in charge, and believe they were looking out for my safety.
That being said, evacuations for minimal storms is another thing. Sometimes I believe they overreact to smaller storms and force evacuations when evacuations aren't necessary, on the other hand, look at Miami, they had a pretty tough go with just a Cat 1, so it's a hard call.
As someone wisely said yesterday, evacuate you can always go back later. If you stay you have no choice later.
