Awareness and Engagement
Communication systems issuing warnings about forecasted dangerous heat conditions have been shown to reduce mortality during extreme heat events.
Establish an extreme heat warning system with information about the duration and severity of the heat event as well as directing residents to cooling resources in the community.
Considerations for Use
Heat alerts should be disseminated through multiple channels such as social media, radio, television, text and phone call alerts to ensure the largest reach. The timing and resulting effectiveness of the first official announcement will establish a community’s level of trust in the system.
