Weatherizing Infrastructure in the North and Terrorism Emergency Readiness Act of 2025

This bill requires the Department of Homeland Security (DHS) to conduct a terrorism preparedness exercise specifically during extreme cold weather events (like polar vortexes). The exercise must test how critical infrastructure failures from such weather could cascade during a terrorist attack, including coordination between federal, state, local, tribal, territorial agencies, and private sector partners. DHS must then submit a report on the exercise findings and lessons learned to relevant congressional committees within 60 days. The bill does not create new programs or funding but mandates this specific readiness drill to improve response planning. (Procedural bill; summary limited to 1-2 sentences as required.)
