At least two people died when Typhoon Kammuri tore through the Philippines, forcing Manila airport to shut.
At least 200,000 residents were evacuated from coastal and mountainous areas over fears of flooding, storm surges and landslides.
The storm landed south of the capital Manila. The deaths were reported on the central island of Mindoro.
Some events at the Southeast Asian Games, which opened on Saturday, were cancelled or re-scheduled.
Operations at Manila airport were suspended for 12 hours starting 11:00 on Tuesday (03:00 GMT).
One Canadian traveler who arrived in Manila from the central island of Cebu on Monday said it was “the most turbulent flight” she ever took.
“I just discovered what airsickness is,” Constance Benoit, 23, told the AFP news agency.
Typhoon Kammuri, locally named Tisoy, made landfall in Sorsogon province, and is said to have sustained winds of up to 155km/h (96mph), with gusts of up to 235km/h.
Storm surges of up to three metres (nearly 10ft) are expected, the weather service said.
Tens of thousands had already fled their homes in the east of the country, where the typhoon was expected to hit first.
But some decided to stay despite the storm’s impending arrival.
“The wind is howling. Roofs are being torn off and I saw one roof flying,” Gladys Castillo Vidal told AFP news agency.
“We decided to stay because our house is a two-storey made of concrete… hopefully it can withstand the storm.”
Organisers of the Southeast Asian Games have suspended some competitions, including windsurfing, adding that other events would be delayed if necessary.
But there is no plan to extend the games, which are due to end on December 11.
The country is hit by an average of 20 typhoons each year. -BBC
