Extreme Weather and Heat Response Modernization Act

HR 3661, the Extreme Weather and Heat Response Modernization Act, requires FEMA to review and update how it defines "incident periods" (timeframes for disaster response) for extreme weather events. Within one year, FEMA must form an advisory panel with diverse emergency management representatives to assess current procedures, particularly for slow-onset, compound, or cascading disasters, and submit findings to Congress. The bill also mandates FEMA to issue new guidance on community cooling centers, resilience centers, and extreme heat/cold mitigation projects within a year, and conduct a study on impacts to vulnerable communities, infrastructure, and emergency alerts. These changes directly affect FEMA, state/local emergency managers, and communities facing extreme heat or cold events by modernizing response protocols and funding eligibility.
