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, and plowed through the agricultural region at the start of the onslaught.
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 5 million people were at risk from the storm, which the Hawaii-based Joint Typhoon Warning Center downgraded 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 raincloud band 900 kilometers (560 miles) wide, combined with seasonal monsoon rains, the typhoon dumped intense rain that could set off landslides and flash floods. Storm warnings have been raised in almost all the provinces across the Luzon, including the capital, Manila, 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 kilometers (127 miles) per hour and gusts of up to 255 kph (158 mph), 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 told reporters late Friday in Manila.
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-story hotel where workers were busy hammering up wooden boards to protect glass panels.
In 2016, a super typhoon wrought heavy damage to Banez's hotel and the rest of Cagayan.
Ninia Grace Abedes abandoned her bamboo hut and hauled 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.
More than 15,300 people had been evacuated in northern provinces by Friday afternoon, the Office of Civil Defense 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.
The typhoon hit at the start of the rice and corn harvesting season in Cagayan, a major agricultural producer, prompting farmers to scramble to save what they could of their crops, Cagayan Gov. Manuel Mamba said. The threat to agriculture comes as the Philippines tries to cope with rice shortages.
After the Philippines, the Hong Kong Observatory predicts Mangkhut will aim at 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 pack sustained winds of 175 kph (109 mph), 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, near 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 coordinating 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 Guangdong and Hainan have been put on hold. Fujian province to the north of Guangdong is also closing beaches and tourist sites, the agency reported.
Philippine forecasters said the shifting typhoon could possibly blow toward Vietnam after it exits late Saturday or early Sunday.
In an emergency meeting Thursday, Philippines President Rodrigo Duterte asked Cabinet officials from the north to help oversee disaster-response work and told reporters it was too early to consider seeking foreign aid.
"If it flattens everything, maybe we need to have some help," he said.
Mangkhut, the Thai word for 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, flattened villages, swept ships inland and displaced more than 5 million in the central Philippines in 2013.
