Be prepared for even longer, look at the people who lost everything in a hurricane or tornade and had to relocate becaue there was no home to return to. You have to rent an apartment or hotel or somehting and live there.
Short term can even go a week, we had just moved before hurricane Katrina came through and knocked power lines down in our city. Out old neighborhood was without power for 8 days and this is in columbus OH, quite far from hurricane territory.
