#Flood Watch

A Flood Watch is in effect for the western portion of the state due to deep tropical moisture that is drawn northward over the state. Kauaʻi, Niʻihau and Oʻahu are under the Flood Watch from Wednesday night through Thursday afternoon.

The National Weather Service says heavy rain on the north side of a developing tropical system (the future Nolo) should develop Wednesday afternoon. Windward and southeast Big Island and windward Maui are the most likely to experience heavy rain.

The National Weather Service has issued a Flood Watch for Niʻihau, Kauaʻi, Oʻahu and Maui County through this afternoon.

A disturbance approaching from the northwest is expected to renew deep tropical moisture across all Hawaiian Islands beginning late tonight. Given saturated soils and elevated stream levels following recent heavy rainfall, flooding may redevelop quickly. A Flood Watch has been extended to 5 p.m. on Monday.

An extratropical cyclone, which is different than a kona low, is drawing deep tropical moisture north into the islands which will continue to support periods of heavy rainfall and strong southerly winds. Isolated strong to severe thunderstorms also are possible, particularly from Thursday through Friday.

A Flood Watch is in effect for the entire state through Friday afternoon. The National Weather Service reports that low pressure developing west of the islands will draw abundant moisture northward as it strengthens during the next couple of days. This will bring potential for heavy rain and thunderstorms leading to flash flooding over all Hawaiian islands.

The National Weather Service has extended the Flash Flood Warning for Maui until 10:30 a.m. At 7:16 a.m., radar showed heavy rain over east Maui. Rain was falling at a rate of 1 to 2 inches per hour. The heaviest rain is falling over the Kaupō area. Additional heavy showers are expected through the morning. Flash flooding is ongoing.

No areas remain under MEMA evacuation warnings; however, some potentially high-impact areas remain under evacuation advisories out of an abundance of caution.

The National Weather Service has issued a Flash Flood Warning for the island of Hawaiʻi until 3:45 p.m.

A kona low, currently north of the islands, has drawn abundant moisture northward. Rounds of moderate to heavy rainfall are anticipated. The heaviest rain is expected to last through tonight.

A kona low developing west of the islands will draw abundant moisture northward as it strengthens and eventually departs to north early next week. Several rounds of moderate to heavy rainfall are anticipated.

The National Weather Service has issued a Flash Flood Warning for the island of Molokaʻi until 2:30 a.m. At 11:34 p.m., A line of heavy showers with embedded thunderstorms moving in from the west is producing rainfall rates of 1 to 3 inches per hour.

The new kona storm forecast to reach the state beginning today follows a severe kona storm that impacted the state March 13 to 16, 2026. Maui received the highest rainfall totals in the state from the first kona storm, and wind speeds were second highest in the state, according to NWS data. Flooding and wind severely damaged portions of South Maui, ‘Īao, Upper Kula, East Maui and Lahaina.

A kona low developing west of the islands will draw abundant moisture northward as it strengthens and eventually departs to north early next week. Several rounds of moderate to heavy rainfall are anticipated. The heaviest rain is expected Friday night through Saturday.

The large and powerful kona storm that has been slowly moving across the Hawaiian Islands, is expected to begin lifting northeastward today into Monday, with heavy rain and strong winds easing across the state, according to the National Weather Service. However, periods of unsettled wet weather in a light and variable low level wind pattern will continue across the state through next week.

A powerful kona storm is producing periods of hazardous weather impacts across the Hawaiian Islands through the weekend. Threats range from significant flash flooding, damaging winds, strong to severe thunderstorms, and snow and ice over the highest Big Island summits. Maui is under a High Wind Warning through Sunday morning and a Flood Watch through Saturday afternoon.

A powerful and slow-moving kona low northwest of the islands will bring a prolonged period of hazardous weather to the state through the upcoming weekend. Expect periods of heavy rain, bringing the potential for flash flooding, strong kona winds, and strong to severe thunderstorms.

The risk for flash flooding will begin today for Kauaʻi, tonight for Oʻahu, Wednesday for Maui County, and Wednesday night for Hawaiʻi Island. The potential for strong to severe thunderstorms and damaging southerly winds is expected to increase significantly statewide late in the week and into the weekend.

A powerful kona storm will begin impacting the western end of the state as early as Tuesday, then spread across the remainder of the island chain by midweek.

The Flood Advisory for the island of Maui was canceled at 1:29 p.m. A Flood Watch remains in effect until 6 p.m. for Kahoʻolawe, Lānaʻi, Maui, and Molokaʻi.
