Lane has been downgraded to a tropical storm, though heavy rains from the system still could cause flash flooding, the National Weather Service said at 5 p.m. Friday.

Lane had weakened rapidly over the past 24 hours with maximum sustained winds of 70 mph. The former Category 5 hurricane will experience further weakening over the next two days and may become a remnant low-pressure system today or Sunday, the weather service said.

The sluggish system was moving northwest at 3 mph and was expected to turn west while increasing speed over the next couple of days, the weather service said.

On the current forecast track, Lane will pass south of Kauai today. It was 170 miles southwest of Kahului, 160 miles southwest of Kaunakakai and 145 miles southwest of Lanai at 5 p.m. Friday, the weather service said.

The hurricane warning was downgraded to a tropical storm warning for Maui County late Friday afternoon. Tropical storm force winds extended 140 miles from the center of Lane and will affect Maui County into today, the weather service said.

Excessive rainfall remains possible into the weekend, which could bring flash flooding and landslides, the weather service said. Lane is expected to produce rain totals of 10 to 20 inches in some areas.

A flash-flood warning for East Maui and the West Maui Mountains had been posted for Maui County until Friday evening. Radar showed heavy rain of 1 to 3 inches over the slopes of Haleakala and into the West Maui Mountains on Friday afternoon, the weather service said.

Nearly 4 inches of rain fell at West Wailuaiki in East Maui in the 24-hour period ending at 1 p.m. Friday. More than 1 inch fell in Puu Kukui in the West Maui Mountains, Haiku and Kula.

The affected areas included Kahului, Honokohau, Kahakuloa, Haliimaile, Paia, Makawao, Wailuku, Waihee, Kaanapali, Kula, Keanae, Nahiku and Pukalani.

The heavy rains closed Hana Highway near Mile Marker 20 and Piilani Highway at Mile Marker 37 near Kaupo on Friday evening, the weather service reported.

Large swells generated by Lane will impact exposed south and east shorelines through today, the weather service said.

A high-surf warning was in effect for south-facing shores of Maui County into this morning. Surf of 15 to 25 feet was expected.

Tropical storm conditions had begun hitting the county Thursday night into Friday. There were reports of broken branches and downed trees.

The high winds from Lane damaged electrical equipment and knocked out power to 4,800 customers in West Maui. Repair work was hampered by a major brush fire in West Maui on Friday, said Maui Electric spokeswoman Shayna Decker.

On Friday evening, MECO asked customers to prepare for an extended outage through today. Access to damaged wires and poles was restricted due to the fire Friday.

About 30 poles were broken, cracked or downed from Lahaina to Kaanapali. Repairs also need to be made to two of the three transmission lines feeding West Maui. The remaining transmission line, running on steel poles, remains in service with enough capacity to serve the area.

Power was restored to critical infrastructure, including the Lahaina Fire Station, Lahaina Police Station and the Lahaina Civic Center, which is serving as an emergency shelter, Decker said.

The Maui Police Department was increasing patrols in the affected West Maui areas Friday evening.

On Molokai, repair crews were able to restore power in an outage that affected 2,600 customers. All but six were restored by Friday night.

Should customers experience any outages or encounter downed power lines, report them to Maui Electric’s trouble line at 871-7777 on Maui or toll-free for Lanai or Molokai at (877) 871-8461.

Because of the West Maui outage, west side residents and businesses were “strongly urged” to conserve water today, a county news release Friday night said. The Department of Water Supply is unable to operate its pumps due to the power outage, and the surface water treatment facilities cannot process the muddy water inflow.

After power is restored, it will take some time to restore tank levels. Customers should use water for health and safety purposes only until Sunday.

Customers are asked to check www.mauicounty.gov for updates and only call the 24/7 service line in case of water emergency.

The state Transportation Department reported clearing trees and branches from state highways and that some traffic signals were out due to power outages.

Airlines announced cancellations of flights into Maui County airports Friday.

Hawaiian Airlines canceled flights from Honolulu and San Diego on Friday into Kahului Airport.

American Airlines joined United, ‘Ohana by Hawaiian, Mokulele and Aloha Airlines Cargo in canceling flights into Kahului Airport on Friday.

Alaska Airlines flights between 10 a.m. and 2 p.m. and Makani Kai flights to Kalaupapa Airport also were canceled Friday.

All departing and arriving passengers were advised to check their flight status and confirm their reserved seats with their airline before going to the airport.

Kahului Airport remained open and had power restored Thursday following an outage. The airport was not closed during the outage, running on generator power.

Five passengers stayed in the terminal overnight at their request while other passengers were put on other flights or put up in hotels, the Transportation Department said.

Kapalua Airport was sheltering people displaced by the fire in Lahaina on Friday morning.

There were more than 900 people in Maui County shelters, which included people who fled their homes due to the fire in West Maui, county officials said Friday morning. There were 300 evacuees inside the Lahaina Civic Center and another 200 people outside. The fire drove evacuees from Lahaina Intermediate to the Lahaina Civic Center.

Maui High had 225 evacuees; Lokelani Intermediate in Kihei, 75; King Kekaulike in Pukalani, 64; Molokai High, 21; Lanai High, 17; and Hana High, two.
