Typhoon Xangsane ploughed into the Philippines on Thursday, killing at least 11 people and leaving dozens missing as it ripped down power lines and cut off electricity for tens of millions of residents.
Gale-force winds uprooted trees, blocked off major highways and damaged buildings while heavy rains caused widespread flooding in central and northern areas. Schools, financial markets and transport links were shut down.
The storm, packing winds up to 110 kilometers per hour and on course to hit Vietnam next, caused severe flash flooding that in places forced people onto the rooftops of their homes.
One woman was electrocuted by a downed power line and 10 others were killed by falling trees, walls and other debris, according to government emergency officials.
A dam burst in Cavite province, south of Manila, and the governor Irineo Malicsi said there were preliminary reports that as many as 30 people were missing.
In Calauan, also south of the capital, where one of the victims was killed, four other people were missing and feared dead after a landslide buried a house, local police said.
As a precaution, officials shut down electricity throughout Luzon, the largest island of the Philippines, leaving around 43 million people without power.
"The problem is that the lines are disconnected," said Energy Secretary Raphael Lotilla. "There are many severed lines."
Two of the main highways leading to Manila were closed due to flooding, fallen trees and scattered debris.
