One of the most important instruments meteorologists use in tracking a storm, Doppler weather radar is used to identify the location of precipitation. This U.S. National Weather Service (NWS) Multi-Radar/Multi-Sensor (MRMS) base reflectivity mosaic covers the region surrounding the main Hawaiian Islands at approximately 1-km (0.6-mile) resolution and updates every 4 minutes. It is compiled from Next-Generation Radar (NEXRAD) and Terminal Doppler Weather Radars (TDWR) and provided as a Web Map Service (WMS) by NOAA nowCOAST^™.
