The Ocean Prediction Center (OPC) is an integral component of the National Centers for Environmental Prediction (NCEP) located at the NOAA Science Center in Camp Springs, MD. The primary responsibility is the issuance of marine warnings, forecasts, and guidance in text and graphical format for maritime users. Also, the OPC quality controls marine observations globally from ship, buoy, and automated marine observations for gross errors prior to being assimilated into computer model guidance. The Ocean Prediction Center also provides forecast points in coordination with the National Hurricane Center (NHC) for Tropical Cyclones in the Atlantic Ocean E of 65W.
