Hurricane Lane has continued its slow crawl across Hawaii on Friday, drenching the main islands with up to three inches of rain per hour and threatening to bring catastrophic flash flooding and 20-foot surf.   

Popular tourist destinations Maui and Oahu, the state's most populated island, are preparing for the thick of the storm to pass over this weekend, bringing heavy rains and winds of up to 105mph. 

Red Cross officials reported that as of Thursday night, more than 1,500 people across the state have checked into shelters to they wait out the 'perilously close' storm. 

The Category 3 hurricane is heading north after having unleashed 31 inches of rain on the Big Island through Wednesday and Thursday.

Stunning drone footage shows the large swaths of flooding in the town of Hilo, where rivers and streams are overflowing and roads and fields - including the high-traffic Bayfront Highway - have been overwhelmed with rainfall.

The onslaught of rain on the Big Island caused waterways to rise rapidly and spill over into populated areas in Hilo, which sits on the island's eastern short.

Five California tourists had to be rescued from a flooded holiday home after a nearby gulch overflowed on Thursday.

Suzanne Demerais described the tiny waterfall and small stream that was flowing near the home when she and four friends from the Los Angeles first arrived - a stark contrast from the torrent it has become in just 24 hours.  

Hawaii County firefighters, who were in touch with the home's owner, decided to evacuate the group before the water rose further, floating the visitors out on their backs.

Despite having been downgraded to a Category 3 storm on Thursday, experts warn Lane has the potential to become the single-costliest hurricane in Hawaii's recorded history - as well as the costliest in all of the US for the 2018 hurricane season, which runs from June to November. 

'Lane could potentially cause in excess of $10billion in damage due to its forecast impacts as well as the increase in population, property, property value and infrastructure on the Hawaiian Islands since then,' AccuWeather President and Founder Dr Joel Myers said. 

The damage from Hurricane Lane will be caused mainly by flooding, high tides and beach erosion rather than winds, which are still clocking in at near 125mph.

A stunning video captured by local resident Victoria Naboa shows a waterspout churning off of the Big Island's eastern shore on Thursday afternoon.  

Officials have warned of the dangers posed by the spout - a tornado that forms over water due to the instability created by the presence of a thunderstorm.  

Tornadic waterspouts 'are associated with severe thunderstorms, and are often accompanied by high winds and seas, large hail, and frequent dangerous lightning,' according to the National Oceanic Atmospheric Administration.

They can be particularly dangerous for boaters and swimmers because they create swirling winds at the water's surface.

Forecasters said 'excessive' rain will continue into the weekend over the island and hurricane warnings remain in effect for Hawaii County, Maui County, and Oahu.  

The storm itself is only moving at 6mph, which forecasters warn could actually raise the risk for 'life-threatening flash flooding and landslides' across the islands. Some areas could see up to 30 inches of rain. 

Lane is forecast to pull away from Hawaii by late Saturday due to increasing wind shear weakening the storm. 

In response to the erratic weather, airlines have been waiving fees, capping fares and tweaking flight schedules through Monday.  

Some flights have been canceled, but others were added to help travelers get from Hawaii to the mainland. 

United grounded all of its Maui flights on Friday after adding two additional flights from Honolulu to San Francisco on Thursday.

The storm remains dangerous even as it's been downgraded to a Category 3, which means it has winds from 111 to 129mph

'Rain has been nonstop for the last half hour or so, and winds are just starting to pick up,' said Pablo Akira Beimler, who lives on the coast in Honokaa on the Big Island. 'Our usually quiet stream is raging right now.'

Beimler, who posted videos of trees being blown sideways, said staying put is about the only choice he has. The road to Hilo was cut off due to landslides, he said. 

'Hurricane Lane is still a dangerous and powerful storm,' Hawaiian Gov Dave Ige said in a news conference on Thursday. 

Honolulu Mayor Kirk Caldwell likewise warned that Lane was 'wide and very moist' and 'going to hang around for awhile'. 

President Donald Trump has issued an emergency disaster declaration, authorizing the Department of Homeland Security and FEMA to coordinate disaster-relief efforts with the state.

'Our teams are closely coordinating with the state and local authorities,' he tweeted Thursday. 'You are in our thoughts!'

In Oahu, employees of the Sheraton Waikiki resort were seen filling sandbags to protect the ocean-front hotel from heavy rain, flash flooding and surging surf - just as many stores along the towns glitzy Kalakaua Avenue have done.  

Police on loudspeakers told surfers and swimmers to get out of the water, saying the beach would be closed until further notice.     

A siren alarm went off on Thursday afternoon to warn those who needed to seek shelter before nightfall and buses were made available to transport people to safety.

While no injuries have yet been reported, two campers have become trapped in a Hawaii valley due to Lane's heavy rainfall.    

Hawaii County Managing Director Wil Okabe says the campers called to report they were trapped Wednesday in Waipio Valley on the Big Island's northern coast.

Emergency workers haven't been able to contact the campers since then because of poor cellphone reception. 

And crews cannot search for the trapped campers because of landslides and rivers of rain blocking the roads.

Steve Goldstein, of the National Oceanic and Atmospheric Administration, said at a news conference on Thursday that Lane is expected to soak the Big Island before heading toward Maui and Oahu.

Goldstein said a direct strike is not needed to see a significant impact from such a strong hurricane. 

Meanwhile, federal officials said they were prepared to help people on the islands.

Brad Kieserman, of the Red Cross, said there were 16 emergency shelters open and 283 people across the island already in them.

US Navy ships and submarines based in Hawaii were also instructed to leave port to avoid damage. 

All vessels not currently undergoing maintenance were being positioned to help respond after the storm, if needed.

Navy aircraft will be kept in hangars or flown to other airfields to avoid the storm.

Unlike Florida or Texas, where residents can get in their cars and drive hundreds of miles to safety, people in Hawaii are confined to the islands and can't outrun the powerful winds and driving rain.

Instead, they must stay put and make sure they have enough supplies to outlast prolonged power outages and other potential emergencies.

'Everyone is starting to buckle down at this point,' said Christyl Nagao of Kauai. 'Our families are here. We have businesses and this and that. You just have to man your fort and hold on tight.'

Living in an isolated island state also means the possibility that essential goods can't be shipped to Hawaii if the storm shuts down ports.

'You're stuck here and resources might not get here in time,' Nagao said.

The Hawaiian government began positioning generators and other aid in Hawaii well before Lane's anticipated arrival.    

FEMA administrator Brock Long said Thursday the supplies arrived in Hawaii after a volcano began oozing lava into neighborhoods in May and in preparation for a recent hurricane that bypassed the islands.

After Hurricane Maria hit Puerto Rico last year, a FEMA report noted that one of its main issues was not having enough generators and other emergency aid on the island before the storm.

In response, officials stockpiled such items in hard-to-reach areas such as Hawaii and Alaska.

FEMA says the agency had also been talking with grocers to make sure food sources are stocked. 

Shelters opened Wednesday on the Big Island and on the islands of Maui, Molokai, and Lanai. Officials urged those needing the Molokai shelter to get there soon because of concerns that the main highway on the island's south coast could become impassable. 

Officials were also working to help Hawaii's sizeable homeless population, many of whom live near beaches and streams that could flood.

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

Authorities also warned that the shelters are not designed to withstand winds greater than about 40mph and that for most people they should be a 'last resort.'

'Whenever possible, the public should plan to shelter in place or stay with family or friends in homes outside of these hazard areas that were designed, built or renovated to withstand anticipated conditions,' the city and county of Honolulu said in a statement. 

Public schools were closed for the rest of the week and local government workers were told to stay home unless they're essential employees.

'We're planning on boarding up all our windows and sliding doors,' Napua Puaoi of Wailuku, Maui, said after buying 16 pieces of plywood from Home Depot. 'As soon as my husband comes home - he has all the power tools.'

Molokai real estate agent Pearl Hodgins said she expected the island's two stores to soon run out of bottled water and batteries.

Melanie Davis, who lives in a suburb outside Honolulu, said she was gathering canned food and baby formula.

'We're getting some bags of rice and of course, some Spam,' she said of the canned lunch meat that's popular in Hawaii.

She was organizing important documents into a folder - birth and marriage certificates, Social Security cards, insurance paperwork - and making sure her three children, all under four, have flotation devices such as swimming vests - 'just in case.'

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.
