Probably no where permanent. They’ll have to move to the locations that fit their current needs much as I and many other economic migrants.
If they do not have the resources to make the move, I have complete empathy for them and am willing to vote for politicians who will allocate my tax dollars towards helping those people out of their current issue.
If, however, they refuse to move because of some non economic reason then that is a lifestyle choice they will have to shoulder the burden of. If one of my representative politicians tries to use my tax dollars to help them continue their untenable lifestyle choices I will vote for their competitor.

Don’t include Texas in that. The other groups have had weather systems of increasing severity that are massively expensive to build against. Texas had weather they declared was unforseeable when they had hit the temperature multiple times in the previous 20-30 years and refused to spend a relatively small amount of money to winterize their generators and mitigate the problem.
