A powerful kona storm will begin to impact the state as early as Tuesday for the western end of the state and spread across the state on Wednesday. While flash flooding is a major concern (more details can be found on our Hydrologic Outlook ESFHFO), there is increasing confidence for strong to severe thunderstorms on Wednesday especially for the western half of the state. Damaging winds will likely be the greatest threat with any of the strong thunderstorms, but large hail can't be ruled out either. While details remain uncertain beyond Wednesday, a much stronger wave of thunderstorms and damaging kona winds may be possible Friday into the weekend.

ESFHFO 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.
