Is the infrastructure secure for power? I heard this storm would wipe it out.
There will be some point, away from the impact area, where the grid is serviceable. That's where you start. Emergency plans generally call for creating rings around an affected area of known reliable services (water, electrical, sewer etc.). Emergency crews first seek to shore up the reliability of the rings, then seek the quickest routes to move from that ring into the center of the affected area, basically creating spokes on a wheel, and then connecting those spokes closer in, thus establishing a new smaller ring or reliable service. THis goes on until reliable services are available at the heart of the affected area. It's hard work and requires smart planning. However, without a reliable service starting point you cannot hope to provide safe water or electric, and that is what emergency planners and medical personnel will need to save lives.
There will be some point away from the Gulf Coast where power is reliable. You find that point, ensure you have redundancy, and begin fighting your way into the middle.
