Hydrologic Outlook HIZ001-003-004-006-007-009>011-015>018-022-023-026>054-090415- Hydrologic Outlook National Weather Service Honolulu HI 408 AM HST Sun Mar 8 2026 ...HEAVY RAIN AND FLASH FLOODING POSSIBLE FROM TUESDAY INTO NEXT WEEKEND... A large low pressure system developing northwest of the state over the next couple of days will pull a very moist southern air mass northward across the state. This will likely initiate periods of heavy rain and occasional thunderstorms that will increase the probabilities of flooding over Kauai County and Oahu from Tuesday onward. The flooding threat will likely expand eastward to include the entire state from Tuesday night into next weekend. Storm total rainfall amounts from Tuesday through Saturday are currently forecast to range from 4 to 12 inches across the state during this five day time period. Locally higher amounts are possible, likely driven by slow moving strong thunderstorms or heavy rain bands. Stay weather aware the next several days as this system develops and the details of the impacts become more clear. The next couple of days would be a good time to clear storm drains and culverts of debris, or anything else that can block the flow of water. Keep up to date with the latest forecast information through the Internet (weather.gov/hawaii), local media, social media, or NOAA Weather Radio broadcasts. $$ RCB
