National Weather Service Wind Gust Forecast

This map displays the forecasted wind gust over the next 72 hours across the Contiguous United States, Alaska, Guam, Hawaii, and Puerto Rico. Wind Gust is the maximum 3-second wind speed (in knots) forecast to occur within a 2-minute interval at a height of 10 meters Above Ground Level (AGL). Wind gust forecasts are valid at the top of the indicated hour. Data are updated hourly from the National Digital Forecast Database (NDFD) produced by the National Weather Service. Where is the data coming from? The National Digital Forecast Database (NDFD) was designed to provide access to weather forecasts in digital form from a central location. The NDFD produces gridded forecasts of sensible weather elements. NDFD contains a seamless mosaic of digital forecasts from National Weather Service (NWS) field offices working in collaboration with the National Centers for Environmental Prediction (NCEP). All of these organizations are under the administration of the National Oceanic and Atmospheric Administration (NOAA).
