The area of landfall had been under a Hurricane Warning for a long, long time (as Hurricane Warnings go.)
I'm attempting to find a record of the evac orders but pretty extensive mandatory evacs were ordered there, and relatively early (as evacs go.)
As you pointed out though hurricane warnings went up for the west coast faily early on and that means 'pay attention'.
I hope they don't try and blame this on Jeb Bush, he did the best he could with the information given to him.
