Hurricane Lane churned dangerously close to Hawaii's Big Island, delivering up to 35 inches of rain to some areas in 24 hours.

The torrential downpour led to landslides and extreme flooding on Thursday and Friday in several areas and the town of Hilo on the island's east side was hit especially hard with roads and fields completely submerged in water.

A National Weather Service meteorologist described flooding on Hawaii's Big Island as catastrophic, with parts of the island soaked with 35 inches of rain in 48 hours.

Chevy Chevalier said the "the sponge is full," meaning the ground is so wet that additional rain to will pond up and flood.

Water levels on the Wailuku River and Honolii Stream surged, and a waterspout, a tornado that forms over water, was spotted off the coast of Paukaa just north of Hilo.

The National Weather Service reported 31.21 inches at its remote Hakalau Station in Hilo.

Police warned people to stay off all roads in South Hilo.

Emergency crews rescued five California tourists from a home they were renting in Hilo after a nearby gulch overflowed and it flooded Thursday.

Suzanne Demerais said a tiny waterfall and small stream flowed near the home when she first arrived with four of her friends from the Los Angeles area. But the stream turned into a torrent and the river rose rapidly over 24 hours. Hawaii County firefighters, who were in touch with the home's owner, decided to evacuate the group before the water rose further. They floated the five out on their backs, Demerais said.

"It was quite an experience because we weren't planning to have a hurricane during our vacation time," Demerais said.

Forecasters say Hurricane Lane is moving away from the Big Island but could still drop more rain there. The storm will move close to or over parts of Hawaii's main islands late Friday.

The dangerous Category 3 hurricane is heading north with maximum sustained winds of 120 mph. The center is about 200 miles south of Honolulu and moving north at 5 mph.

Sirens wailed while workers piled sandbags in front of hotels and police blared warnings to tourists to leave the world-famous Waikiki Beach on Oahu island.

Lane was not projected to make a direct hit on the islands, but officials warned that even a lesser blow could do significant harm. Some areas could see up to 30 inches (about 80 centimeters) of rain.

United Airlines canceled its Friday flights to and from Maui. The airline added two additional flights from Honolulu to San Francisco on Thursday to help transport people off the islands.

Hawaiian Airlines canceled all Friday flights by its commuter carrier, Ohana by Hawaiian.

Hawaii's biggest hotels are confident they can keep their guests safe as long as they stay inside, said Mufi Hannemann, CEO of Hawaii Tourism and Lodging Association.

"The only concern is those that venture outside of the properties, that would like to hike on a day like this or who would like to still go into the ocean and see what it's like to take a swim or surf in these kind of waters," Hannemann said.

Honolulu shopping malls and office buildings closed early on Thursday and planned to shut their doors Friday.

Shelters were open throughout the islands, with 350 people in them in Oahu. Aid agencies were also working to help Hawaii's sizable homeless population, many of whom live near beaches and streams that could flood.

Because there's not enough shelter space statewide, Hawaii Emergency Management Agency Administrator Tom Travis urged people who were not in flood zones to stay home.

The National Weather Service downgraded the Big Island to a tropical storm warning, meaning it expects sustained winds of 39 mph to 73 mph on the island instead of stronger hurricane force winds.

But a hurricane warning remains in effect for Oahu and Maui County.

The central Pacific gets fewer hurricanes than other regions, with about only four or five named storms a year. Hawaii rarely gets hit. The last major storm to hit was Iniki in 1992. Others have come close in recent years.

Because people in Hawaii are confined to the islands, they have to make sure they have enough supplies to outlast power outages and other potential emergencies.

The Federal Emergency Management Agency moved several barges packed with food, water, generators and other supplies into the region ahead of Hurricane Hector, which skirted past the islands more than a week ago, FEMA Administrator Brock Long said.

"Hurricane Lane is not a well-behaved hurricane," Gov. David Ige said in a statement. "I've not seen such dramatic changes in the forecast track as I've seen with this storm. I urge our residents and visitors to take this threat seriously and prepare for a significant impact."
