The USCG NavAid hosting the site was removed and changed to a buoy. In fact, all navigation aids on the river are being switched to buoys, so we do not know if we will be able to find another location.
Time displayed is based on Gunpowder, MD local time. The wind graph displays observations as reported in miles per hour. The blue line and shaded area represents the average wind speed, the red represents gust value, and the green represents lull. Dots along the lines indicate time of data reported. The yellow arrows represent observed wind direction. An arrow pointing down indicates wind blowing from north to south, and is commonly referred as a "north wind". Note: frequency (and latency) of data is a function of the individual reporting station. Many non-WeatherFlow stations report data only once per hour. Check sensor notes for information on data source. Please read and understand disclaimer
