The Philippines evacuated 200,000 people in coastal and mountainous areas due to fears of flooding and landslides and said it would also shut its main global airport as a powerful typhoon was set to make landfall on Monday night.
Organisers have said there are contingency plans in place for a typhoon, including possible cancellations of outdoor events of the Games, which are mostly in the main Philippine island of Luzon in the country's north.
The storm, which made landfall in Sorsogon province, is said to have maximum sustained winds of 175 km/h (110mph), with gusts of up to 240km/h, with storm surges of up to three metres (nearly 10ft) expected, the weather service said.

Officials at Manila's airport made the call to shut the facility once the storm's power was clear.
A powerful typhoon drew closer to the Philippines on Monday, forcing tens of thousands of villagers to flee to safety, knocking out power in entire provinces and prompting authorities to plan the closure of Manila's worldwide airport.
More than 60,000 people were asked to leave their homes in Bicol region, authorities said.
However, some residents opted to stay put even as the storm began to strike.More news: The New Found Black Hole Is Monstrous in Size
Kammuri is already snarling plans for the SEA Games, which opened Saturday for thousands of athletes from the region and is set to run through to December 11 in and around Manila. "Roofs are being torn off and I saw one roof flying", said local Gladys Castillo Vidal. "Hopefully it can withstand the storm".
Windsurfing was cancelled and triathlon events were held earlier than scheduled. The 20th storm to enter the Philippines this year is following a track similar to typhoon Rammasun in July 2014, which killed 106 people in the southeast Asian country and damaged properties worth 38.6 billion pesos ($759 million).
Ramon Suzara, the chief operating officer of the organising committee, said contingency plans were in place for bad weather, but the duration of the Games would not be extended.More news: White House Christmas Decorations, Melania Unveils Patriotic Theme
