Agreed wardamneagle. I evacuated from Ivan. I left a day earlier than most (that Monday), and got out before the traffic. I was not a seasoned hurricane person, but 3 days before, I gassed up, got water, money out of the ATM, supplies, etc.
As I was making my way out, that was when 90% of the rest of the people were stuck in gas lines and stuck in traffic.
If people wait too long, then your committed.
Just leave. Unless youre close to a hospital
your power will be out for weeks. Gasoline will
be out because gas trucks wont be able to get in and pumps wont have power. Cell towers will be down. Same with food stores. Just stay away until power is back.
