Experimental Warning Program


2024 NOAA Hazardous Weather Testbed activities will have both virtual and in-person opportunities.

The Experimental Warning Program (EWP) is a part of the NOAA Hazardous Weather Testbed at the National Weather Center in Norman, Oklahoma. The HWT EWP mission is to improve the nation's hazardous weather warning services by bringing together forecasters, researchers, trainers, technology specialists, and other stakeholders to test and evaluate new techniques, applications, observing platforms, and technologies.

The annual Spring Experiment provides forecasters with a first-hand look at the latest research concepts and products, and immerses research scientists in the challenges, needs, and constraints of front-line forecasters. The EWP helps transition severe weather research and technology to improve the Weather Forecast Office’s severe weather warnings for hail, wind, and tornadoes. The EWP tests research concepts and technology specifically aimed at short-fused warnings of severe convective weather.
