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.

...WINTER STORM WATCH FOR BIG ISLAND SUMMITS ABOVE 12500 FEET... .An upper low will enhance moisture over the Big Island and bring the potential for both freezing rain and snowfall. * WHAT...Freezing rain, significant ice accumulation and snowfall will all be possible. Total snow accumulations up 3 inches and ice accumulation up to a quarter inch possible. Winds could gust as high as 55 mph. * WHERE...Big Island Summits above 12,500 feet in elevation. * WHEN...From Wednesday morning through Friday afternoon. * IMPACTS...Ice accumulations and snow on roads from this storm will make travel to the summits very difficult to impossible. Snowfall may accumulate on top of ice. Visibility will be significantly reduced.

A Winter Storm Watch means there is potential for significant snow or ice accumulations that may impact the summits. Anyone planning travel to the summits, including hikers and campers, should monitor the latest forecasts and consider postponing their trip until improved weather returns.

Flood Watch issued April 7 at 3:08AM HST until April 10 at 6:00PM HST by NWS Honolulu HI

...FLOOD WATCH FOR ALL ISLANDS IN THE STATE OF HAWAII... * WHAT...Flash flooding caused by excessive rainfall is possible. * WHERE...The island of 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.
