HANOI/HAIPHONG, Sept 9 (Reuters) - Typhoon Yagi, Asia's

most powerful storm this year, left dozens dead in northern

Vietnam and widespread damage as it churned westwards,

preliminary government estimates showed on Monday, while the

weather agency warned of more floods and landslides.

Thirty five people have died and 24 are missing, mostly

because of landslides and floods triggered by the typhoon,

Vietnam's disaster management agency said.

The typhoon made landfall on Saturday on Vietnam's

northeastern coast, home to large manufacturing operations of

domestic and foreign companies, and was downgraded to a tropical

depression on Sunday by the meteorological agency.

It cut power to millions of households and companies,

flooded highways, disrupted telecommunications networks, downed

a medium-sized bridge and thousands of trees and brought to a

halt economic activity in many industrial hubs.

Managers and workers at industrial parks and factories in

Haiphong, a coastal city of two million, said on Monday they had

no electricity and were trying to salvage equipment from rain in

plants whose metal sheets roofing had been blown away.

"Everyone is scrambling to make sites safe and stocks dry,"

said Bruno Jaspaert, head of DEEP C industrial zones, which host

plants from more than 150 investors in Haiphong and the

neighbouring province of Quang Ninh.

A factory in Haiphong of South Korea's LG Electronics

collapsed, according to pictures and a Reuters

witness.

LG Electronics, a major maker of appliance and consumer

electronics, did not immediately reply to requests for comment.

"Lots of damages," said Hong Sun, the chairman of the South

Korean business association in Vietnam when asked about the

typhoon's impact on Korean factories in coastal areas.

A manager of leased factories confirmed widespread damages

to roofs and prolonged power cuts in northern provinces.

A bridge in the province of Phu Tho collapsed on Monday,

authorities said.

"This is normally a busy bridge, a key bridge in the

province," a senior official of the province's transport

department said, adding there was no report available yet on

casualties.

The weather agency warned of more floods and landslides,

noting that rainfall ranged between 208 millimetres and 433

millimetres (8.2 inches to 17.1 inches) in several parts of the

northern region over the past 24 hours.

State-run power provider EVN said that more than 5.7 million

customers lost power during the weekend as dozens of power lines

were broken, but electricity was restored on Monday to nearly

75% of those affected.
