Hydrologic Outlook issued March 8 at 4:32PM HST by NWS Honolulu HI

Effective: Sun March 8, 2026, 4:32 PM
Expires: Mon March 9, 2026, 6:45 AM

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 initiate periods of heavy rain and thunderstorms, along with the likelihood of flooding, especially from early Wednesday onward across the state. While the flooding threat will likely begin over Kauai County and Oahu late Tuesday, the flooding threat will begin to amplify and spread eastward across the state early Wednesday as a strong short-wave trough swings through. With latest guidance showing an even more significant band of moisture moving in Friday into the weekend and lingering uncertainty in general, it is still too early to forecast specific rainfall totals. However, confidence is growing for considerable flooding impacts, especially over leeward areas. 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.

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.
