I think the local news folks are referring to the many camps along the coast that are jacked up about 20 ft above ground that many people live in. Mass marketing hyped up fear, now with more dirty sea water!

This is a very minor hurricane. The storm surge is expected to be 3-5 ft. Everybody already knows what levels of hurricanes they can ride out and what levels they need to evacuate from.
