OP, you have an emergency management agency of some kind for your area. They will have all kinds of info on how to prepare for any disaster (and they even know what kinds of disasters are most likely to affect your area).

If you’re in the US, try Google county name and emergency management agency or state name emergency management agency. Follow their socials! Check out their webpages! And please please sign up for whatever alerting/notification system they use to update residents on ongoing/evolving events.
