Big Island Saturday severe weather updates: Flood advisory canceled shortly before set to expire

Update at 5:16 a.m. Saturday, April 11, 2026: National Weather Service forecasters in Honolulu canceled the flood advisory that was in effect until 5 a.m. Saturday, April 11. It was nixed at 4:43 a.m., just 17 minutes before it was set to expire.

Radar shows heavy rain has diminished and flooding is no longer expected to pose a threat.

A flood watch remains in effect, however, until 6 p.m. Monday, April 13, for the entire state, including the Big Island.

Update at 3:40 a.m. Saturday, April 11, 2026: The National Weather Service in Honolulu issued a new flood advisory that now is in place until 5 a.m. Saturday for the entire Big Island because of excessive rainfall.

It also extended the flood watch in place for the entire state — including the Big Island — through 6 p.m. Monday.

A flood advisory means conditions for minor flooding are imminent occurring, while a flood watch means conditions are favorable for flooding, so be prepared.

The winter weather advisory and the wind advisory previously in place for the Big Island were canceled.

At 1:47 a.m. Saturday, National Weather Service radar and automated rain gauges indicated  moderate to heavy rain falling at 0.5 to 1.5 inches an hour over the Big Island.

Flooding on roads and in poor drainage areas and streams, which also are already elevated, can be expected.

Some locations that will experience flooding include Kailua-Kona, Captain Cook, Waikoloa Village, Kapaau, Hōlualoa, Honalo, Puʻu Anahulu, Kāʻināliu, Kahaluʻu-Keauhou, Kalaʻoa, Kealakekua, Pōhakuloa Training Area, Hōnaunau, Puakō, Kawaihae, Waimea, Kohala Ranch, Pololū Valley, Hala‘ula and Hāwī.

Forecasters in Honolulu extended the flood watch for the state because a disturbance approaching from the northwest is expected to renew deep tropical moisture across all Hawaiian Islands beginning late Saturday night.

Given saturated soils and elevated stream levels following recent heavy rainfall, flooding could redevelop quickly.
