HMAG Act of 2024

The HMAG Act of 2024 creates a new federal grant program under FEMA to help states and local governments prepare for and respond to extreme heat events. It allows the President to provide grants, equipment, and personnel for heat mitigation without requiring a formal major disaster declaration, provided states submit detailed assessments of potential life loss, revenue impact, and infrastructure risks. The bill also mandates FEMA, NOAA, and CDC to establish a scientific threshold defining "extreme heat events" within 90 days of enactment. This directly affects local governments in heat-prone areas by offering targeted federal support for heat-related emergencies.
