Such an analysis of specific IWT partner participation provides a unique glimpse at how the current NWSChat communication infrastructure would operate in the age of FACETs (Forecasting a Continuum of Environmental Threats). FACETs is a next-generation approach to NWS watches/warnings that will deliver user-specific, probabilistic hazard information (PHI) for improved decision making. As research with severe convective PHI matures and approaches operational use, an outstanding question exists about how PHI and other new temporal gap-filling products will affect the dynamics of IWT communication. This study will provide an overview of NWSChat trends and participation in an environment in which a continuous flow of information was provided to IWT partners.
