Hydrologic Outlook issued April 4 at 8:55AM HST by NWS Honolulu HI

Effective: Sat April 4, 2026, 8:55 AM
Expires: Tue April 7, 2026, 6:00 PM

ESFHFO Southerly winds associated with low pressure developing northwest of the islands will draw a very moist tropical airmass northward early next week. This will bring periods of heavy rain and a risk of flash flooding. The most likely period for significant impacts is Wednesday night through Thursday night. However, afternoon shower development over island interiors on Tuesday may be heavy as well. The duration of flooding potential remains less certain than usual as deep moisture remains over the state into the middle of April leading to potential for additional waves of heavy rain next weekend or beyond. Now would be a good time to clear storm drains, culverts, and other drainage areas of debris to help reduce localized flooding. This outlook will be updated daily or sooner if needed. Stay up to date with the latest forecast information through weather.gov/hawaii, local media, social media, or NOAA Weather Radio broadcasts.

...FLOOD WATCH FOR ALL ISLANDS IN THE STATE OF HAWAII... * WHAT...Flash flooding caused by excessive rainfall is possible. * WHERE...Kauai, Niihau, Oahu, Maui, Molokai, Lanai, Kahoolawe, and the Big Island. * WHEN...From Wednesday morning through Friday afternoon. * IMPACTS...Significant flooding may occur due to excessive rainfall and 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... - A deep layered trough will develop west of the islands and draw abundant moisture northward as it strengthens on Tuesday. Instability and upward forcing will enhance the available moisture and bring the potential for heavy rain and thunderstorms leading to flash flooding across all islands in the state of Hawaii.

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