My house is rated at 180 MPH and it held fine during Charley except for all the trees, the roof tiles, and some other damage. My shelter is rated for a 15 cm sFH 18.
In any case I see no excuse for not being prepared beyond having the FEMA 800 number.
Ah, but are you also prepared for all the good old boys in the area who will find you and your supplies afterwards? That is my biggest concern.
