Vietnam was struck by a record-breaking number of 16 tropical storms a year ago that left 389 people dead or missing and injured 668 others, mostly in northern and central regions.
On Sunday morning, Mangkhut was barreling toward densely populated southern China and Hong Kong, where authorities raised the highest storm warnings and moved almost a half-million people to shelter from seven cities.
Hong Kong airport - one of the most important global transit hubs - was closed, with over 500 flights cancelled and some 100,000 passengers affected, according to a Bloomberg report. People in China and the Philippines are struggling to pick up the pieces as the typhoon left a trail of death and destruction.
The death toll in the Philippines has been raised to at least 65, while 43 others are missing following landslides and building collapses.
Numerous missing in the Philippines are gold miners and their families feared buried in a landslide after seeking shelter in a bunkhouse-turned-chapel in a village in Benguet province.
More than 2.4 million people had fled in southern China's Guangdong province by Sunday evening, state media said.
Hong Kong Security Minister John Lee Ka-chiu (李家超) urged residents to prepare for the worst.
The Philippines took the brunt of the typhoon Saturday when it hit as a Category 5 storm, with 165 miles per hour winds.
Guangdong is also China's most populous province, with a population of more than 100 million. About 63,000 people have been affected, and the damage has not yet been fully assessed as numerous worst-hit areas are rural.
Rescuers were hampered by rain and mud, and the search and rescue operation was suspended at nightfall and will resume at daybreak Monday, Palangdan said. Dozens of residents sought shelter there during the storm despite warnings it was risky.
The death toll from Typhoon Mangkhut in the Philippines has reached 28, a police director said Sunday, attributing the count mostly to landslides in the nation's northern provinces that were triggered by the storm.
For Hong Kong, a metropolis that has shrugged off tropical storms in the past, Mangkhut was different.
Macau, China's gaming center, was forced shut down all its casinos for the first time its history Sunday as Mangkhut approached.
"Remain where you are if protected and be prepared for destructive winds and the change in wind directions", warned the Hong Kong Observatory, the city's meteorological agency, in an alert on Sunday afternoon.
Lohas Park, a residential estate in the district, saw the windows of many of its units shattered by Mangkhut's strong winds, leaving the flats in a great mess.
But the head of the military's Northern Luzon Command, Emmanuel Salamat, told Reuters that at least 19 more were killed in landslides in one part of Benguet province.
