My sister is a snow bird, not down there yet, but there is a mandatory evacuation where her house is (barrier island in Brevard County).
Her friend is riding it out, which is crazy, there is a single road north-south for much of the length of the barrier island, it could be lost to the storm swell or debris and they will be in real peril out there.
There is a webcam at Sebastian Inlet, for as long as it stay up and connected:

I wonder if your sister’s friend is my FIL :). He’s 3 miles north if Sebastian Inlet in A1A and is going to ride it out.
