And there are other natural events (fires, mudslides, tornadoes, tsunamis, earthquakes -- you get the picture) that also need consideration if one is thinking about moving somewhere else within the USA.
One alternative is to move to an in-state area where the threats may be less pronounced; coastal Florida is especially vulnerable, so a move to the central part of the state might be a preferred immediate solution.
We had a place in Sarasota for 30 years, and although we didn't have the routine street flooding problems other neighborhoods in the area experienced, nontheless the house was only 22 ft. above sea level. After selling that house we bought another further inland (about 25 miles from the coast) and more northerly in an area of rolling hills (yes, for those who don't know, Florida isn't completely flat as a pancake).
As do all Florida residents, we keep an eye on hurricane tracks during the season and hope we're far enough inland to not be impacted by any major storms, although Irma passed over the area (and Sarasota) the year before we bought -- and seeing the tremendous damage caused by Michael 60 miles inland from its landfall was quite sobering.
We personally like living in Florida, despite the political climate; one can get close to nature here (because nature will sometimes visit you in your living room), and spectacular sunsets are routine. That being said, we prefer life in California; the cultural and natural diversity makes us glad we have a second home there.
