Typhoon Mangkhut barreled into southern China on Sunday after lashing the northern Philippines with strong winds and heavy rain that left at least 36 people dead and dozens more feared buried in a landslide.
More than 2.4 million people had been relocated in southern China's Guangdong province by Sunday evening to flee the massive typhoon and nearly 50,000 fishing boats were called back to port, state media reported. The gambling enclave of Macau closed casinos for the first time and the Hong Kong Observatory warned people to stay away from the Victoria Harbour landmark, where storm surges battered the sandbag-reinforced waterfront.
Mangkhut made landfall in the Guangdong city of Taishan at 5 p.m., packing wind speeds of 162 kilometers (100 miles) per hour. State television broadcaster CGTN reported that surging waves flooded a seaside hotel in the city of Shenzhen.
Groceries flew off the shelves of supermarkets in the provincial capital of Guangzhou as residents stocked up in preparation for being confined at home by the typhoon, China's official Xinhua News Agency said.
Authorities in southern China had issued a red alert, the most severe warning, as the national meteorological center said the densely populated region would face a "severe test caused by wind and rain" and urged officials to prepare for possible disasters.
Hundreds of flights were canceled. All high-speed and some normal rail services in Guangdong and Hainan provinces were also halted, the China Railway Guangzhou Group Co. said.
In Hong Kong, a video posted online by residents showed the top corner of an old building break and fall off while in another video, a tall building swayed as strong winds blew.
The storm also broke windows, felled trees, tore bamboo scaffolding off buildings under construction and flooded areas with sometimes waist-high waters, according to the South China Morning Post.
The paper said the heavy rains brought storm surges of 3 meters (10 feet) around Hong Kong.
Hong Kong Security Minister John Lee Ka-chiu urged residents to prepare for the worst.
"Because Mangkhut will bring winds and rains of extraordinary speeds, scope and severity, our preparation and response efforts will be greater than in the past," Lee said. "Each department must have a sense of crisis, make a comprehensive assessment and plan, and prepare for the worst."
Hong Kong's Cathay Pacific said all of its flights would be canceled between 2:30 a.m. Sunday and 4 a.m. Monday. The city of Shenzhen also canceled all flights between Sunday and early Monday morning. Hainan Airlines canceled 234 flights in the cities of Haikou, Sanya, Guangzhou, Shenzhen and Zhuhai scheduled this weekend.
In Macau, next door to Hong Kong, casinos were ordered to close from 11 p.m. Saturday, the first time such action was taken in the city, the South China Morning Post reported. Macau suffered catastrophic flooding during Typhoon Hato last year, leading to accusations of corruption and incompetence at its meteorological office.
In Macau's inner harbor district on Sunday, the water level reached 1.5 meters (5 feet) and was expected to rise further. The district was one of the most affected by floods from Typhoon Hato, which left 10 people dead.
In the northern Philippines, about 40 to 50 people, mostly small-scale miners and their families, were feared to have been trapped by a landslide in the far-flung village of Ucab in Itogon town in Benguet province, Itogon Mayor Victorio Palangdan said by phone.
Palangdan said three villagers who nearly got buried by the huge pile of mud and rocks told authorities they saw residents rush into an old three-story building, a former mining bunkhouse that has been transformed into a chapel, at the height of the typhoon's onslaught Saturday afternoon.
"That was not an authorized evacuation center," Palangdan said, but expressed sadness that the villagers, many of them poor miners, had few options to survive in a region where big corporations have profited immensely from gold mines.
Police Superintendent Pelita Tacio said rescuers pulled out seven bodies from the huge mound of mud and rocks. She said they were scrambling to pull out the body of another victim before she left the area Sunday.
