The Advanced Quantitative Precipitation Information (AQPI) Project is building a state-of-the-art observation and forecast system across the Greater San Francisco Bay Area. The “backbone” of this system consists of strategic radar installations (5 X-band and 1 C-band radars) that provide high-resolution data in both space and time for real-time analysis, nowcast initialization, short-term forecast model improvement, and forcing for hydrologic models. Coupling this enhanced observational capability with a powerful suite of weather forecast products developed at the Center for Western Weather and Water Extremes yields a powerful decision support platform for partners and stakeholders covering a spectrum of forecast lead times from ~10 days to current conditions. This presentation will provide an overview of the AQPI project, current major efforts, examples of success, and future plans.
