Mandatory evacuation orders are issued to save the lives of residents as well as first responders. If you choose to ignore the mandatory evacuation order, be prepared to be self-sufficient during, and for the first 72 hours after, a storm. High winds during storms prohibit travel of emergency response vehicles and debris following storms may also prevent travel. In addition, mandatory evacuations also include closure of hospital facilities. This means medical care is unavailable until after evacuation orders are lifted.
