Special Weather Statement issued March 9 at 3:20AM HST by NWS Honolulu HI

Effective: Mon March 9, 2026, 3:20 AM
Expires: Mon March 9, 2026, 4:30 PM

A powerful kona storm will begin impacting the western end of the state as early as Tuesday, then spread across the remainder of the island chain by midweek. While flash flooding remains a major concern (see the Flood Watch and Hydrologic Outlook for additional details), confidence is increasing that strong to severe thunderstorms may develop Wednesday into the weekend. Damaging winds will likely be the primary hazard with these storms, though large hail cannot be ruled out. In addition to the heavy rainfall and severe thunderstorm threat, strong and potentially damaging kona winds are possible late in the week and into the weekend.
