The Office of Water Prediction (OWP) conducts operational, development, and field support functions. The OWP operationally supports and delivers science-based, integrated, consistent, timely, reliable and accurate water resources monitoring, prediction and diagnostic information to the Nation. It operates and maintains numerical water resources analysis and forecast modeling and data assimilation systems in collaboration with National Weather Service (NWS) National Centers for Environmental Prediction (NCEP), 13 regional NWS River Forecast Centers, Federal water partners, academia and stakeholders. OWP development functions focus on advancing the maturity and transitioning to field operations applied research (R2O) from within the National Oceanic and Atmospheric Administration (NOAA), partner agencies, and academia, as well as supporting and improving core OWP operational capacity. The NWC coordinates, facilitates and integrates development activities across NWS River Forecast Centers. The OWP provide support services to regional and local field offices and others. In large scale and severe events, the NWC coordinates and communicates with field offices to ensure a common operating picture for all of the offices to work from, assists with media inquiries to provide a national perspective, provides maps and briefing materials, provides safety and awareness information, and prepares and delivers ad hoc data and related support services.
