A new company called PriorityEvac, which launched in June, is offering private evacuation flights from Florida’s coasts. A PriorityEvac evacuation is triggered based on a hurricane’s timing and intensity using National Hurricane Center forecasts. Murgio said they looked at 22 years of Florida hurricane data and found the evacuation window was usually between 36 to 60 hours. Florida disaster authorities advise that people need only evacuate tens of miles, not hundreds, but PriorityEvac sends people to Atlanta. Hurricane evacuation is already a two-tier system, experts say.
