US: evacuate 3 days, stay home 2 weeks

American Red Cross planning often separates a go-kit you can carry from stay-at-home supplies for longer sheltering.

• Go-kit (~3 days): water, food, radio, light, meds, copies of documents — in a backpack.
• Home (~2 weeks): larger water/food store, comfort items, full med supply, hygiene.
