HMAG Act of 2025

The HMAG Act of 2025 creates a new FEMA grant program to help state and local governments prepare for and respond to extreme heat events, such as heatwaves causing health risks or infrastructure damage. It requires applicants to submit assessments of past heat-related life loss, revenue impacts, and infrastructure vulnerabilities before receiving aid. FEMA must coordinate with NOAA to establish a formal temperature/duration threshold for qualifying heat events within 90 days of the bill's passage. This program allows funding for mitigation and emergency assistance without requiring a formal disaster declaration, directly supporting communities facing climate-driven heat risks.
