The Ocean Prediction Center (OPC), established in 1995, is one of the National Centers for Environmental Prediction's (NCEP's) original six service centers. Until January 12, 2003, the name of the organization was the Marine Prediction Center. Its origins are traced back to the sinking of the Titanic in 1912. The OPC issues forecasts up to 5 days in advance for ocean areas north of 31N latitude and west of 35W longitude in the Atlantic, and across the northeast Pacific north of 30N latitude and east of 160E longitude. Until recently, the OPC provided forecast points for tropical cyclones north of 20N latitude and east of 60W longitude to the National Hurricane Center.
