Activities of the 2023 Hazardous Weather Testbed Experimental Warning Program

The NOAA Hazardous Weather Testbed (HWT) is a joint project of the National Severe Storms Laboratory, Storm Prediction Center, and National Weather Service (NWS) Norman Weather Forecast Office. The HWT provides a conceptual framework and a physical space to foster collaboration between research and operations to test and evaluate emerging technologies and science for NWS operations. The HWT consists of two primary programs: the Experimental Forecast Program and the Experimental Warning Program (EWP). The EWP tests and evaluates new applications, techniques, and products to support Weather Forecast Office (WFO) severe convective weather warning operations.

In 2023, the EWP hosted 5 experiments over the course of 14 operational weeks. Amazon Web Services (AWS) were used to host AWIPS-2 in the cloud to meet various experimental needs for both in-person and virtual experiments. AWIPS-2 was utilized, along with a mix of real-time and displaced real-time operations. Experiments for 2023 included: Tiny Threats-in-Motion (Tiny TIM), Hazard Services - TIM, Probabilistic Hazard Information (PHI) Prototype, Satellite Convective Applications, and Watch-to-Warning. A brief overview of each EWP experiment will be discussed.
