NowCOAST

NowCOAST is a web mapping portal that provides spatially referenced links to thousands of real-time coastal observations and NOAA forecasts of interest to the marine community. The portal serves as a "one-stop" website to real-time coastal meteorological, oceanographic, and hydrologic observations from a variety of Internet sites within and outside of NOAA, along with NOAA forecasts. NowCOAST is designed as a planning aid for recreational and commercial mariners, coastal managers, HAZMAT responders, marine educators, and researchers, who can discover and display real-time information for their particular needs and geographic area of interest. NowCOAST covers all U.S. coastal waters including the Great Lakes.
