With the exception of introducing storm-based polygon methodology in 2007, National Weather Service (NWS) hazardous weather warnings have changed little in more than 40 years. While generally viewed as a time-honored means of protecting life and property, the overall warning system is often evaluated for improvements - with the most recent effort being NOAA's Weather Ready Nation initiatives. NOAA's 20-Year Weather Research and Development Vision also lists "reinventing the severe weather warning system" as one of NOAA's "Grand Scientific Challenges." This presentation will introduce a next-generation warning concept intended to help address these challenges and aid in furthering on-going initiatives. The concept, called Forecasting a Continuum of Environmental Threats (FACETs), is simultaneously a new warning paradigm and a comprehensive framework to help focus and direct efforts to improve the science, technology and tools for forecasting environmental hazards of all types. The FACETs concept and its underlying components will be presented for discussion and feedback.
