Typhoon Fengshen showered heavy rains across the eastern and central Philippines on Saturday, grounding domestic flights and inter-island ferry services, officials said.
The storm forced over 200,000 people to seek temporary shelters in the eastern Bicol region, the civil defence office said, but there were no immediate reports of casualties.
The typhoon also uprooted small trees and blew away tin roofs in the central city of Roxas, where Fengshen was hovering early Saturday with maximum sustained winds of 140 kilometres an hour.
"Fengshen was forecast to dump heavy rains in large parts of the central Visayas region and parts of the main island of Luzon," the weather bureau said.
Residents in low-lying areas and near mountain slopes were warned against possible flash floods and landslide, while those in coastal areas were told to watch out for big waves.
Officials said that domestic flights going to the central Philippines have been suspended, while inter-island ferry services were also halted.
"There have been flights cancelled," said Office of Civil Defense deputy head Anthony Golez, advising residents to stay indoors.
"If there are untoward incidents, the armed forces are prepared to deploy," he said.
He said that there have been no reports of any casualties, but said up to 200,000 people were evacuated to temporary shelters in the Bicol region as a precaution.
Government agencies were also instructed to stockpile on relief goods, while state-run hospitals were placed on alert.
