Workshop on Improving Sub-seasonal to Seasonal Precipitation Forecasting to Support Water Management

The Western States Water Council and the California Department of Water Resources cosponsored a recurring workshop to continue a dialogue among western states, the National Oceanic and Atmospheric Administration (NOAA), and the research community on improving sub-seasonal to seasonal (S2S) precipitation forecasting to support water management decision-making. 

Improving precipitation forecasts at lead times longer than a two-week weather forecast would support many water management activities, including preparedness and response to drought conditions that are again gripping much of the western U.S.  Workshop presentations will include recently developed experimental research forecast products for California and the Colorado River Basin, predictability analyses, the status of efforts to begin a western pilot project to improve forecasting, model development activities, and examples of needs and potential applications for improved forecasts.
