in my experience, you run off to stay with relatives in another city, or get a cheap motel, all on your own dime. there might be evacuation centers at the fairgrounds or something, where you could set up a tent, but that wasn’t an option for us what with my partner’s asthma and how smoky it was in town last time, so i don’t know any details about that. i’ve never known smoke to do any lasting damage once it has dissapated, but it ain’t good to breath if it’s too thick.
