The National Digital Forecast Database (NDFD) is a suite of products generated by the National Weather Service (NWS) using data from regional NWS Weather Forecast Offices (WFOs) and the National Centers for Environmental Prediction (NCEP). The database provides access to forecasts produced at WFOs, as well as NCEP gridded model data enhanced by WFO staff. The NWS uses these products to make text, graphic, and digital products for emergency managers and the public. The NDFD also provides data for commercial weather companies to generate their own products based on NWS forecasts.
