City monitoring potential for rain and wind next week

The City is closely monitoring forecasts from the National Weather Service (NWS). Current forecasts show the potential for moderate to heavy rain and gusty winds in the middle of the coming week. According to the NWS, “…it is still too early to accurately determine amounts and which islands would be most affected. Please keep yourself updated through the weekend for the latest forecasts.” The City will provide updates as the system moves closer to the islands. Any weather watches, advisories, or warnings will be sent to HNL Alert subscribers when they are issued by the NWS. Visit weather.hnlalert.gov for latest weather updates.
