National Weather Service Wind Forecast

This map displays the wind forecast over the next 72 hours across the contiguous United States, in 3 hour increments, including wind direction, wind gust, and sustained wind speed.Zoom in on the Map to refine the detail for a desired area. The Wind Gust is the maximum 3-second wind speed (in mph) forecast to occur within a 2-minute interval within a 3 hour period at a height of 10 meters Above Ground Level (AGL). The Wind Speed is the expected sustained wind speed (in mph) for the indicated 3 hour period at a height of 10 meters AGL. Data are updated hourly from the National Digital Forecast Database 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).Wind Speed Source: https://tgftp.nws.noaa.gov/SL.us008001/ST.opnl/DF.gr2/DC.ndfd/AR.conus/VP.001-003/ds.wspd.binWind Gust Source: https://tgftp.nws.noaa.gov/SL.us008001/ST.opnl/DF.gr2/DC.ndfd/AR.conus/VP.001-003/ds.wgust.binWind Direction Source: https://tgftp.nws.noaa.gov/SL.us008001/ST.opnl/DF.gr2/DC.ndfd/AR.conus/VP.001-003/ds.wdir.binWhere can I find other NDFD data?The Source data is downloaded and parsed using the Aggregated Live Feeds methodology to return information that can be served through ArcGIS Server as a map service or used to update Hosted Feature Services in Online or Enterprise.What can you do with this layer?This map service is suitable for data discovery and visualization. Identify features by clicking on the map to reveal the pre-configured pop-ups. View the time-enabled data using the time slider by Enabling Time Animation.Alternate SymbologyFeature Layer item that uses Vector Marker Symbols to render point arrows, easily altered by user. The color palette uses the Beaufort Scale for Wind Speed. https://www.arcgis.com/home/item.html?id=45cd2d4f5b9a4f299182c518ffa15977 This map is provided for informational purposes and is not monitored 24/7 for accuracy and currency.If you would like to be alerted to potential issues or simply see when this Service will update next, please visit our Live Feed Status Page!

本图展示了未来72小时美国大陆范围内的风速预测，以3小时为间隔，包含风向、风速阵风以及持续风速。通过放大地图，可以精细选定区域的详细信息。风速阵风是指预计在2分钟内，于地面以上10米高度（AGL）出现的最大3秒风速（以英里每小时为单位），在3小时周期内的预测。风速是指在地面上10米高度（AGL）预计的持续风速（以英里每小时为单位）。数据每小时从国家数字预报数据库（NDFD）更新，该数据库由国家气象服务局生产。数据来源为何？国家数字预报数据库（NDFD）旨在从中央位置提供数字形式的天气预报访问。NDFD生成网格化预报的感观气象要素。NDFD包含国家气象服务局（NWS）各区域办公室与国家环境预报中心（NCEP）协作生成的无缝数字预报镶嵌。所有这些机构均隶属于国家海洋和大气管理局（NOAA）管理。风速数据来源：https://tgftp.nws.noaa.gov/SL.us008001/ST.opnl/DF.gr2/DC.ndfd/AR.conus/VP.001-003/ds.wspd.bin风速阵风数据来源：https://tgftp.nws.noaa.gov/SL.us008001/ST.opnl/DF.gr2/DC.ndfd/AR.conus/VP.001-003/ds.wgust.bin风向数据来源：https://tgftp.nws.noaa.gov/SL.us008001/ST.opnl/DF.gr2/DC.ndfd/AR.conus/VP.001-003/ds.wdir.bin欲查询其他NDFD数据，可访问：使用聚合实时流方法下载并解析源数据，以返回可通过ArcGIS服务器作为地图服务提供的信息，或用于更新在线或企业中的托管要素服务。该图层可用于数据发现和可视化。通过点击地图识别特征，以揭示预配置的弹出窗口。通过启用时间动画使用时间滑块查看时间序列数据。替代符号学：使用矢量标记符号渲染点箭头的要素层项目，用户可轻松修改。调色板采用蒲福风级来表示风速。https://www.arcgis.com/home/item.html?id=45cd2d4f5b9a4f299182c518ffa15977 本地图仅供参考，不进行24/7的准确性和时效性监控。如需了解潜在问题或查看下一次服务更新时间，请访问我们的实时流状态页面！
