Interoffice Collaboration: Current NWS Practice and Implications for a Probabilistic Hazard Information (PHI) Future

When storms move between NWS County Warning Areas (CWAs), a number of non-meteorological factors can influence the way severe hazard warnings are handled across borders. These factors can include technological constraints within an office, policy and philosophy within an office, and relationships between an office and its neighboring offices. This presentation will provide an overview of results from a study conducted in the summer of 2019 that explored each of these factors for a subset of NWS offices in the four CONUS regions. The presentation will conclude with a preview of an upcoming NOAA Hazardous Weather Testbed (HWT) experiment that will apply these results in interoffice collaboration simulations where traditional warnings are replaced by continuously-updating Probabilistic Hazard Information (PHI).
