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.

Hydrologic Outlook issued April 5 at 2:39PM HST by NWS Honolulu HI

ESFHFO A significant pattern change is expected to begin Tuesday as an upper disturbance and surface low pressure system evolve northwest of the islands. This system is expected to draw deep tropical moisture northward over the state, leading to an extended period of moderate to breezy southerly winds, increasing chances for widespread rainfall, and renewed flooding concerns from late Tuesday through next weekend. Now is a good time to prepare for possible flooding impacts: - Clear gutters, storm drains, culverts, and drainage areas of debris to improve water flow - Move valuable items out of low-lying or flood-prone areas - Check pumps, generators, and emergency equipment to ensure they are operational - Take stock of emergency supplies, including food, water, medications, flashlights, and backup power sources - Review family emergency plans and check on neighbors and family, especially those in flood-prone locations Residents living near streams, rivers, gulches, valleys, ravines, and flood-prone areas should remain especially alert and be prepared to move to higher ground if flash flooding develops. 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, and NOAA Weather Radio broadcasts.
