At least 25 have people died in China and 27 in the Philippines after Typhoon Usagi swept over the South China Sea and caused floods in southern China's Guangdong province, reports say.
Residents of Guangdong's worst-hit city, Shanwei, said the typhoon, which hit land in China late on Sunday, was the strongest for 30 years.
At least 13 people died in Shanwei, while 12 died in three other areas of Guangdong, some 310,000 were evacuated and several thousand homes were destroyed, authorities said on Monday.
"The toll in our city included seven deaths at a railway construction site," state media quoted Xiao Zhan, deputy head of the Shanwei Water Authority, as saying.
"The majority of casualties were due to the collapse of houses where people took shelter," Xiao said.
In nearby Shantou city, a local resident told dpa by telephone that seawater pushed by the typhoon had flooded the streets.
"This time it is quite serious," said the resident, who asked to be identified by the single name Jack.
"The road in front of my apartment is flooded by about 20-30 centimetres of seawater, and I heard that the houses of people living closer to the sea were flooded up to about chest height," he said.
School classes and all air, rail and shipping services were suspended on Monday in 14 cities in Guangdong, as well as the nearby Chinese territories of Hong Kong and Macao, the agency said.
In the Philippines, 27 people died as heavy rain battered the main island of Luzon, officials said.
City officials in Olongapo, 80 kilometres north-west of Manila, said the US embassy had agreed to their request for help by a nearby US Navy ship, as many residents had taken refuge on their roofs.
Usagi killed three people in Vietnam last week, but the storm was predicted to start weakening from Tuesday.
