...FLOOD WATCH IN EFFECT FOR NIIHAU KAUAI AND OAHU... ...FLOOD WATCH IN EFFECT FOR MAUI COUNTY BEGINNING WEDNESDAY MORNING... ...FLOOD WATCH IN EFFECT FOR THE BIG ISLAND BEGINNING WEDNESDAY EVENING... * WHAT...Flash flooding caused by excessive rainfall is possible. * WHERE...Maui, Molokai, Lanai, and Kahoolawe. * WHEN...From Wednesday morning through Saturday afternoon. * IMPACTS...Significant flooding may occur due to the overflow of streams and drainages. Roads in several areas may be closed, along with property damage in urban or low lying spots due to runoff. Landslides may also occur in areas with steep terrain. * ADDITIONAL DETAILS... - Considerable flash flooding is possible beginning early Wednesday as a large and powerful kona storm develops northwest of the state and draws deep tropical moisture across the islands. Persistent bands of heavy rain and thunderstorms may produce intense rainfall rates, leading to rapid rises in streams and flooding of roads and low-lying areas.

You should monitor later forecasts and be prepared to take action should Flash Flood Warnings be issued.

Special Weather Statement issued March 10 at 4:53PM HST by NWS Honolulu HI

Expires: Wed March 11, 2026, 6:00 AM

A powerful kona storm will impact the western end of the state tonight, 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.
