You know what's a social privilege? Disaster prep. An awful lot of people do not have the spare resources to prepare in advance. (Flashback to the people who stuck out Hurricane Katrina in Nola b/c they didn't have bus fare to get out of town.)

As with anything else, take care of your own needs first, but if afterwards you are able to do more, please invest in community resilience and the preparedness of your vulnerable friends, too.
