#flood warning

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.

The threat for widespread flash flooding has decreased across the Hawaiian Islands, therefore, the Flood Watch has been cancelled. However, due to lingering moisture and saturated grounds, some minor flooding may still occur in areas affected by heavy showers.

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.

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.

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.

Maui Emergency Management Agency (MEMA) at 3:30 p.m. today, March 20, 2026, UPGRADED advisories to evacuation WARNINGS for parts of ʻĪao Valley in Central Maui and parts of Kīhei in South Maui due to the potential flooding threat to life/or property amid kona storm 2. Warnings and advisories are NOT mandatory evacuation orders. 

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.

South Kīhei has been identified by MEMA as an area at high-risk of flooding due to significant sediment accumulation from the recent kona low storm. Ongoing cleanup efforts are focused on restoring drainage capacity, but elevated flood risk remains. Other areas of moderate-risk include ʻĪao, East Molokaʻi, Lahaina, and East Maui.

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.

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.

The Flash Flood Watch that was in effect for the Hawaiian Islands has since been cancelled. A Wind Warning continues for Maui County and the Big Island until 6 p.m. East winds of 25 to 35 mph are expected, with gusts up to 60 mph.

All County of Maui offices on Maui, Molokaʻi and Lānaʻi will be closed on Monday, Feb. 9, and only essential personnel will report to work. All County parks and permitted playing fields will be closed on Monday, Feb. 9.
