National Weather Service United States Department of Commerce

On July 26, 2021, the National Weather Service changed the Universal Geographic Codes (UGC) for all Fire Weather Zones in the state of Hawaii. Prior to this date, the Fire Weather Zone UGCs were the same as the Public Forecast Zone UCGs.  This could cause confusion and misprocessing of forecasts and warnings due to the same number designation being used for different geographic areas.  “200” will be added to each existing Fire Weather Zone number to create the new Fire Weather Zone UGCs.

The maps on this page show the new UGCs. Read the Service Change Notice for more details.
