Watch Duty, a free cellphone app used by millions to track wildfires, is expanding to support flood monitoring. Launched for fire incident awareness, the app helps people follow where fires are burning and assess risks during emergencies. Several reports describe how it has been relied on during the 2025 Los Angeles-area fires, when users used the app to decide whether to stay put or evacuate as conditions changed. In the new phase of the expansion, Watch Duty adds flood-related functionality intended to provide similar situational awareness for dangerous flooding events. The coverage frames the move as a response to the broader range of hazards affecting communities, including major storm-driven flooding. One report includes an account from Altadena, California, where a nearby fire prompted urgent decisions for residents in January 2025, illustrating the kind of real-time risk information the app is designed to deliver. While the new flood monitoring features are the focus of the expansion, all sources emphasize that Watch Duty’s goal remains consistent: giving users accessible, timely updates during emergencies so they can better understand local conditions and make safety decisions.
