Yes, they've known for a long time this could happen. Sad that the governor and mayor did so little to prepare.
Like what did you have in mind?
Yes. Of course the residents could have also tuned into the news and maybe figured out that there could be a weather issue. We've braved huge blizzards in upstate NY and took precautionary measures. We cut down trees that would have fallen on the house, turned off and drained water when we lost heat and power so the pipes wouldn't freeze and burst. Stocked wood on the deck for heat in the fireplace, and to heat canned goods to eat. Filled up the tubs and sinks for fresh water.... The list was endless. But we prepared.
In the Gulf situation, things are different. I'd say that most should have taken a bus or train and left in order to not drown, or whatever risk they feel that they might be in.
