Understanding Heat Wave Alerts and How Clime Can Help

Heat waves are prolonged periods of excessively hot weather, often with high humidity, that can pose significant health risks. In the United States, the National Weather Service (NWS) issues specific alerts to inform the public about these conditions.

What Are Heat Wave Alerts?

The NWS issues several types of heat-related alerts:

  • Heat Advisory: Issued when heat indices are expected to reach 95°F to 99°F for at least two consecutive days.

  • Excessive Heat Watch: Issued when conditions are favorable for an excessive heat event in the next 24 to 72 hours.

  • Excessive Heat Warning: Issued when an excessive heat event is expected in the next 24 to 36 hours, with heat indices reaching 105°F or higher.

These alerts are crucial for public safety, as heat-related illnesses can be life-threatening. The Centers for Disease Control and Prevention (CDC) emphasizes that heat is the leading weather-related killer in the U.S., resulting in hundreds of fatalities each year. (cdc.gov)
