One person has died and another remained missing on Friday as typhoon Doksuri brought sustained wind speeds of 135kph (84mph) and heavy rainfall to central parts of Vietnam, where some 289,000 people have been evacuated from the storm.
Trinh Duc Hung, a provincial leader in Thua Thien Hoa, told the VNA state new agency that one person had been killed and another was missing after the storm passed over his region.
The latest reports said the typhoon had reached the northern province of Ha Tinh, where the extreme weather system is due to move west into Laos, dropping intensity gradually.
Torrential rains have caused rivers and reservoirs to bulge causing flooding to cut off roads, while strong winds _ with recorded gusts of up to 185 kph -, have uprooted trees and electric posts and damaged houses.
Around 800 houses in Ha Tinh province have been flooded and the accumulated water has exceeded 20 centimeters (7.8 inches) in parts.
Another 20 houses were damaged in Hue city, the country's former capital located in Thua Thien Hoa province.
Besides Thua Thien Hoa, heavy rainfall and strong winds have lashed the neighboring provinces of Quang Binh and Quang Tri.
The authorities had prohibited all fishing boats from going out in high-risk areas and deployed 250,000 troops, along with a fleet of boats and vehicles, on alert for rescue efforts.
Doksuri is the tenth typhoon so far this year in Vietnam, where natural disasters have claimed the lives of at least 140 people, according to official data.
The typhoon reached Vietnam from the Philippines, where it left four people dead and 18 missing.
Vietnam's Deputy Prime Minister Trinh Dinh Dung on Thursday had warned that Doksuri could be the worst typhoon to hit the country in a decade.
