The "Tornado and Windstorm Innovation for Safety and Tracking Enhancement Research Act," or TWISTER Act , aims to enhance public safety by amending the Weather Research and Forecasting Innovation Act of 2017. This legislation specifically expands the objectives of the existing tornado warning improvement and extension program, building upon previous efforts to protect communities from severe weather. The bill mandates the Under Secretary to prioritize the development of innovative tornado forecasts, predictions, and warnings. The program's expanded focus areas include fast-developing storm systems such as derechos , areas historically absent of tornadoes, and evening or nighttime tornadoes . This ensures a more comprehensive approach to tornado preparedness and response across diverse meteorological conditions and geographic regions.
