Special Weather Statement issued March 9 at 4:02PM HST by NWS Honolulu HI

Effective: Mon March 9, 2026, 4:02 PM
Expires: Tue March 10, 2026, 5:15 AM

A powerful kona storm will begin impacting the western end of the state as early as Tuesday, then spread across the remainder of the smaller islands by midweek and the Big Island towards the end of the week. While flash flooding remains a major concern (see the Flood Watch 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.

ESFHFO Latest forecast models continue to indicate that considerable flash flooding is possible this week beginning as early as Tuesday as a powerful kona storm develops northwest of the state and draws deep tropical moisture across the islands. Higher confidence in the heavy rainfall and flooding threat has led to the issuance of a Flood Watch for Kauai County, Oahu, and Maui County. This will be the final Hydrologic Outlook issued for this event. Further hydrologic threat information will be covered by flash flood watches, flash flood warnings and flood advisories as conditions warrant. Keep up to date with the latest forecast information through the Internet (weather.gov/hawaii), local media, social media, or NOAA Weather Radio broadcasts.
