It is based at the World Weather Building in Camp Springs , Maryland , along with a few of the other National Centers such as the Climate Prediction Center ( CPC ) , the Ocean Prediction Center ( OPC ) , and the Environmental Modeling Center ( EMC ) . The NCEP centers to reside in the facility are the Hydrometeorological Prediction Center ( HPC ) , the Climate Prediction Center ( CPC ) , the Ocean Prediction Center ( OPC ) , the Environmental Modeling Center ( EMC ) , and NCEP Central Operations ( NCO ) .
