Relating to the development of a severe weather adaptation plan by certain entities.

HB 2618 requires 15 major Texas state agencies - including the Department of Transportation, Public Utility Commission, Texas Division of Emergency Management, and Texas Water Development Board - to develop and publish severe weather adaptation plans every even-numbered year. Each plan must include a vulnerability assessment, specific operational steps for severe weather, budget impact analysis for 2/5/10 years, funding sources, and a statewide monitoring strategy based on current climate science. The bill mandates consultation with the Houston Advanced Research Center and Texas State Climatologist during plan development. This procedural law focuses on preparing state agencies for increased severe weather impacts, not on direct funding or policy changes.
