HMAG Act of 2025

This bill would let FEMA help states and local governments prepare for and respond to extreme heat. FEMA could give grants, equipment, supplies, and staff to reduce harm and manage heat emergencies, and would work with NOAA to guide this help. To qualify, a state or local government must submit short assessments, including the possible loss of life and revenue, other available aid, and long‑term impacts like damage to roads and power systems. The federal government could also fund projects that lower future heat risks, even if no major disaster is declared, and FEMA must set clear rules, an appeals process, and what costs are eligible. Within 90 days of the law taking effect, FEMA, NOAA, and CDC must set the temperature and time threshold that counts as an “extreme heat event”.

Key points:

• Who is affected: State and local governments, and communities facing dangerous heat waves.
• What changes: FEMA can provide funding, gear, and staff for extreme heat; coordinate with NOAA; offer risk‑reduction aid even without a major disaster; and set rules and an appeals path for aid.
• When: The heat‑event threshold must be set within 90 days after the law is enacted.
