I wouldn't be surprised if there isn't a single city in the U.S. with an escape plan for a storm/disaster of this magnitude. In 2000, during the coverage of the 100-year anniversary of the Galveston Flood, it was estimated that it would take a minimum of 36 hours to evacuate the island if another storm that size hit. Thirty-six hours. The 1900 hurricane didn't even last that long. What do you think the odds are of such an evacuation going as planned, even if everyone did as they were told, the bridge off the island wasn't damaged, and people weren't in a panic? Not likely.
