HANOI, Vietnam, Aug 25, (AP): Vietnam has evacuated hundreds of thousands of people and closed schools and airports as it braces for Typhoon Kajiki, its strongest storm of the year so far. Forecasters said the typhoon had winds of up to 166 kilometers (103 miles) per hour at 10 am Monday but is expected to weaken slightly before making landfall between central Vietnam’s Thanh Hoa and Ha Tinh provinces later in the afternoon.

The typhoon started as a weak tropical depression on Aug 22 but grew into a powerful storm in less than two days, matching last year's Typhoon Yagi as one of the region's fastest-growing, according to state media. Its rapid strengthening forced Vietnamese authorities to rush emergency measures as strong winds and heavy rain hit the region.

Last year, Typhoon Yagi killed about 300 people and caused $3.3 billion in damage. Kajiki has already caused devastation in China, with strong winds and heavy rain whipping Hainan Island and nearby parts of Guangdong province on Sunday. About 20,000 people were evacuated from high-risk areas, China’s official Xinhua News Agency reported.

One man in Nghe An province died Friday after being electrocuted while trying to secure his roof ahead of the storm, state media reported. The storm is expected to move inland into Laos and northern Thailand. Vietnamese state media reported plans to evacuate nearly 600,000 people in the provinces of Thanh Hoa, Quang Tri, Hue and Danang, where more than 152,000 homes are in high-risk areas.

The government said over 16,500 soldiers and 107,000 paramilitary personnel have been deployed to assist with evacuations and remain on standby for search and rescue. Vietnam halted flights at two airports in Thanh Hoa and Quang Binh provinces on Monday, the Civil Aviation Authority of Vietnam said while dozens of flights have been cancelled.
