Typhoon Mangkhut slams into the Philippines

Typhoon Mangkhut slammed into the Philippines' northeastern coast early Saturday, its ferocious winds and blinding rain ripping off tin roof sheets and knocking out power.

The typhoon made landfall before dawn in the coastal town of Baggao in Cagayan province on the northern tip of Luzon Island, a breadbasket of flood-prone rice plains and mountain provinces often hit by landslides.

More than fivemillion people were at risk from the storm, which the Hawaii-based Joint Typhoon Warning Centredowngraded from a super typhoon but still punching powerful winds and gusts equivalent to a Category 4 Atlantic hurricane.

There were no immediate reports of major damages or casualties in the region, where a massive evacuation from high-risk areas was carried out over two days.

Associated Press journalists in a hotel in Cagayan's capital city of Tuguegarao saw tin roof sheets and other debris hurtle through the air and store signs crash to the ground. Cars shook as wind gusts pummeled a parking lot.

With a huge rain-cloud band 900 kilometreswide, combined with seasonal monsoon rains, the typhoon will bring heavy to intense rain that could set off landslides and flash floods. Warnings have been issued in 25 provinces across the main northern island of Luzon, restricting sea and air travel.

A few hours after landfall, the eye of the typhoon was nearing the western coast of Luzon facing the South China Sea

Before it hit land, Mangkhut packed sustained winds of 205 km/hand gusts of up to 255 m/ph, forecasters said. Even if the typhoon weakens slightly after slamming ashore, its winds will remain very destructive, government forecaster Rene Paciente said.

"It can lift cars, you can't stand, you can't even crawl against that wind," Paciente said at a news conference in Manila.

'We're praying'

In Tuguegarao, residents braced for the typhoon's fury by reinforcing homes and buildings and stocking up on food.

"It was busy earlier in the hardware store, and people were buying wood, nails, tin wire, plywood and umbrellas," said Benjamin Banez, who owns a three-storey hotel where workers were busy hammering up wooden boards to protect glass panels.

A super typhoon wrought heavy damage to Banez's hotel and the rest of Cagayan in 2016. "We're praying that there will be less damage this time, although we know that this one will be very strong."

Ninia Grace Abedes abandoned her bamboo hut and took her four children to a school building serving as an emergency shelter. The 33-year-old laundrywoman said the 2016 typhoon blew away their hut, which they abandoned before the storm hit.

"If we didn't, all of us would be dead," Abedes said.

Homes in the northern provinces were evacuated by Friday afternoon, displacing 15,300 people, the Office of Civil Defence said.

Concerns over massive storm surges that could be whipped inland by the typhoon's winds prompted wardens to move 143 detainees from a jail in Cagayan's Aparri town to nearby towns, officials said.

Preparations in Macau, mainland

After the Philippines, the Hong Kong Observatory predicts Mangkhut will plow into the Chinese mainland early Monday south of Hong Kong and north of the island province of Hainan. Though it is likely to weaken from a super typhoon to a severe typhoon, it will still be packing sustained winds of 175 km/h, it said.

The observatory warned of rough seas and frequent heavy squalls, urging residents of the densely populated financial hub to "take suitable precautions and pay close attention to the latest information" on the storm.

The gambling enclave of Macau, next door to Hong Kong, suffered catastrophic flooding during Typhoon Hato last August that left 10 dead and led to accusations of corruption and incompetence at its meteorological office.

On the Chinese mainland, the three southern provinces of Guangdong, Guangxi and Hainan are co-ordinating preparations, including suspending transport and moving people to shelter inland, the national meteorological agency reported.

Guangdong, China's manufacturing hub, has set up 3,777 shelters, while more than 100,000 residents and tourists have been moved to safety or sent home. The province has recalled more than 36,000 fishing boats to port, while train services between the cities of Zhanjiang and Maoming have been suspended and all ferry services between the Guangdong and Hainan have been put on hold.

Fujian province to the north of Guangdong is also closing beaches and tourist sites and preparing other measures depending on conditions, the agency reported.

Philippine forecasters said the shifting typhoon could possibly blow toward Vietnam after it exits late Saturday or early Sunday.

President Rodrigo Duterte on Thursday asked cabinet officials from the north to help oversee disaster-response work if needed, and told reporters it was too early to consider seeking foreign aid.

"It would depend on the severity of the crisis," Duterte said. "If it flattens everything, maybe we need to have some help."

Officials said other northern provinces had started evacuating residents from high-risk areas, including in northern mountain provinces prone to landslides.

Mangkhut, a Thai word for the mangosteen fruit, is the 15th storm this year to batter the Philippines, which is hit by about 20 a year and is considered one of the world's most disaster-prone countries. Typhoon Haiyan left more than 7,300 people dead or missing and displaced over five million in the central Philippines in 2013.
