Recent Developments in Weather Alert Systems
Updated Terminology
In March 2025, the National Weather Service (NWS) updated its heat-related terminology. The "Excessive Heat Warning" and "Excessive Heat Watch" have been renamed to "Extreme Heat Warning" and "Extreme Heat Watch," respectively, to provide clearer communication about severe heat conditions.
Legislative Improvements
The Weather Alert Response and Notification Act (WARN Act) was introduced in February 2025. This bipartisan legislation mandates studies on emergency alert system effectiveness, focusing on improving timely information dissemination during weather emergencies.
Enhanced Accessibility
To better serve the 68.8 million U.S. residents who don't speak English at home, the NWS is developing an automated translation program using artificial intelligence. This initiative provides accurate translations in languages including Spanish, Simplified Chinese, and Vietnamese, ensuring all communities receive understandable weather information.
