@aeva I am super out of practice with this but having lived in a mobile home in North Dakota for a while as a kid- during watch you need to check if the local shelter is open (in our case the trailer park manager's basement), crack open the windows and unplug unneeded electrical appliances and at warning if you could, go to the shelter, if not, sit in the bathtub. I have no idea these days if most of that was actually useful information.
@jalefkowit good luck, that is no fun at all!
