Preparedness context

Why this page is useful even before an emergency reaches you.

Heat is a quiet emergency

Extreme heat may not look dramatic on a disaster map, but it can become dangerous quickly for vulnerable people and households without reliable cooling.

What to watch before symptoms appear

Heat preparedness should happen before the hottest hours: hydration, shade, cooling, medication planning, and check-ins.

  • Cooling plan
  • Hydration and electrolytes where appropriate
  • Medication and chronic condition awareness
  • Power outage backup
  • Neighbor or family check-ins

Preparedness route

Use heat alerts as a prompt to plan cooling, reduce exposure, and check on one vulnerable person before the hottest part of the day.
