The amateur radio leadership of NWS SKYWARN and Hawaii (State) Emergency Management Agency RACES and DEM (Department of Emergency Management) RACES coordinated a joint net on the state-wide VHF Repeater system for passing storm information to the National Weather Service Honolulu Forecast office at HIG Building, University of Hawaii at Manoa campus, with supplemental traffic for SCD and DEM. The repeaters of DEM RACES (Oahu County) and SCD were linked using ALL-STAR VOIP linking to create a eight node repeater cluster of both State-wide and around-the-island repeaters for Oahu for reporting and monitoring purposes.
