As someone living in hurricane country, the joke around here is that FEMA stands for "Futilely Expecting Meaningful Aid". But really, their job is coordination, and usually will only contribute relief supplies if the state or county/parish is overwhelmed. They have a problem with people expecting too much from them - they are not going to show up in a convoy of trucks with food & water the very next day. But Wal-Mart, HEB, and Waffle House do a fantastic job of post-storm logistics, once the roads & bridges are open.

Anyone who has lived here more than a few years knows that they should prepare for the season and have important papers ready to carry with you, 2 weeks of water & food on hand, etc. but human nature being what it is, many don't. A good site that can help you prepare is https://www.ready.gov/ Check with your relatives and neighbors to make sure they've got the supplies they need or a way to evacuate ahead of the storm.
