Forecast Guidance
NWS and NOS forecast guidance is computer model generated predictions from numerical- and/or statistical-based weather, oceanographic, or river models. Model forecast guidance is used for input into other numerical forecasts models and also by NOAA and private sector meteorologists, hydrologists, and oceanographers in generation of worded or gridded weather, river, and/or marine forecasts. Users should always consult final worded or gridded marine, weather, and/or river forecasts, warnings or advisories from local NWS Weather Forecast Offices for their particular activity or application.
