The Nearshore Wave Prediction System (NWPS) provides on-demand, high-resolution nearshore wave model guidance to U.S. coastal WFOs, triggered in real time by forecast wind grids prepared and submitted by the individual offices. NWPS is maintained and developed by NCEP's Environmental Modeling Center (EMC) in collaboration with a number of Weather Forecast Offices (WFOs), as well as partners at NOAA/NOS, USGS and USACE.
