Start with the basics: estimate water and food needs, check backup power, identify missing supplies, and save a go-bag checklist. The tools run in your browser and don't ask for account details.
These are planning estimates, not live alerts or guarantees. Always follow current official emergency guidance.
An initial baseline, not a substitute for individual medical, accessibility, climate or evacuation needs.

Water baseline: at least 1 gallon per person per day for drinking and sanitation. Store more for hot weather, illness, pregnancy or pets. Food is measured in person-days, not individual meals. Follow local emergency instructions.
