Short items are easier to finish before conditions change. Save official links and adapt supplies to your household, location, and medical needs.

  • Check heat alerts from official weather agencies.
  • Plan cooling options before the hottest hours.
  • Check on older adults, infants, outdoor workers, and people with chronic illness.
  • Drink water and avoid unnecessary exertion in peak heat.
  • Never leave children or pets in parked vehicles.

Guide step

Heat can become an emergency quietly

Extreme heat does not always look dramatic, but it can be deadly. Plan cooling, hydration, shade, and check-ins before symptoms appear.

Guide step

Know who is at higher risk

Older adults, infants, people with chronic conditions, outdoor workers, and people without reliable cooling may need extra support.

Guide step

Use official health guidance

Heat illness symptoms and medical decisions should be guided by health authorities and emergency services in your location.

Official and expert sources

Verify decisions with source-of-record pages.

Disaster Calendar organizes public preparedness information, but it is not an official emergency alert service.
