#flood Maui

An unusually strong upper level disturbance moving over the state will bring the possibility strong to severe thunderstorms, which could produce damaging winds and large hail over the state. The greatest chance for severe thunderstorms will occur during the day Friday through Friday evening, according to the National Weather Service. Listen for later statements, as well as possible watches and warnings, as this event becomes more clear.

Consumers need to be aware that most standard homeowners and renters insurance policies do not cover flood damage. Flood insurance coverages can be purchased separately from the National Flood Insurance Program or endorsed onto the policy to supplement a policyholder’s homeowners insurance.

A Flash Flood Watch is in effect for Maui County, Oʻahu and Kauaʻi from tonight through Wednesday afternoon. 

The National Weather Service has canceled the Flood Advisory that was in effect earlier today for the island of Maui. The NWS reports that weather radar shows the heavy rain has diminished and flooding is no longer expected to pose a threat at this time.

Due to heavy rains, a 2-inch water line broke and is running through a drain culvert on Kula Highway and Lower Kula Road.

Managers from the Hawaiʻi Emergency Management Agency are urging the public to exercise caution amid risks statewide of flooding, landslides and gusty winds.

At 9:36 p.m., radar showed heavy rain over the slopes of Haleakalā, falling at a rate of 1 to 2 inches per hour with locally heavier rain up to 3 inches per hour.

At 8:05 p.m., radar showed heavy rain from nearly stationary thunderstorms anchored over East Maui. Rain was falling at a rate of 2 to 3 inches per hour. The NWS reports that flash flooding is ongoing or expected to begin shortly.

The remnants of former Tropical Cyclone Linda are expected to move through the islands between today and Monday night, according to the National Weather Service.

Additional heavy rain may develop, and the ground remains saturated, thus a Flash Flood Watch remains in effect through 6 a.m. Sunday.

Radar indicated moderate to heavy showers persistently moving into the windward slopes of Haleakalā, with additional showers also affecting windward West Maui.

A flash flood watch is in effect through this afternoon for all islands due to “deep moisture within an unstable easterly flow” that will produce elevated threats of flash flooding today.

South Kīhei Road is now OPEN as of 8 a.m. It was closed earlier this morning between North Kīhei and Uwapo Roads due to flooding.

At 6:02 p.m., radar indicated widespread moderate showers over windward east Maui, with rainfall rates between one and two inches per hour leading to stream rises and ponding of water.

At 8 a.m., radar indicated bands of heavy showers moving over Maui from the east, with peak rainfall rates near 2 inches per hour in the heaviest showers.

At 8:33 p.m. HST, radar showed bands of heavy rain continuing to move over the windward slopes of Haleakala and the West Maui Mountains. Peak rain rates within the bands were 1 to 2 inches per hour.

At 11:30 a.m. HST, radar indicated bands of heavy rain continuing to move over the windward slopes of Haleakalā from the east. The highest rain rates were 1 to 2 inches per hour from Kīpahulu to Keʻanae. Stream levels in the area continue to run above normal. Additional rain bands are expected to move over windward Haleakalā through today.

The National Weather Service says an unstable airmass will move over the islands today into the weekend, bringing an increase in showers across the eastern islands.

The greatest potential for coastal flooding impacts will be this morning and on Friday, especially around the time of the peak high tide, which occurs between midnight and daybreak in most areas.

A flood watch has been extended until this afternoon for all Hawaiian Islands, as an upper level low remains stationary over the western portion of the island chain.
