Khammuan and Borikhamxay provincial authorities have warned villagers living along rivers to be on alert of possible flooding after tropical storm Son-tinh lashed northern and central provinces of Laos this week.
The Xebangfai River has risen above dangerous levels since Wednesday (July 18)and will remain so for the coming days.
“We have warned villagers in five at-risk districts to be prepared,” Director of National Resources and Environment Department of the central province of Khammuan, Mr Sikhay Khamsavath told Vientiane Times yesterday.
The districts affected are Nongbok, Xebangfai, Mahaxay, Yommalath and Bualapha.
Although water has swelled above dangerous levels, it has not yet overflowed the river bank, the director said, adding that the warning was issued just in case.

Data from the Meteorology and Hydrology Department (MHD) showed the Xebangfai River water level in the Xebangfai Bridge area has exceeded the dangerous level of 18.50 metres since July 18.
From July 18-20, water levels were measured at 18.68 metres, 18.82 metres, and 18.75 metres respectively.
The MHD forecast that water levels for today and tomorrow would remain dangerous at 18.67 and 18.60 metres respectively.

The tropical storm lashed Laos from July 18-20 after making landfall in Vietnam. It has caused swollen water levels in the Mekong and its tributaries including the Xebangfai River. Moving at a speed of 35 kilometres per hour, the storm brought heavy rains and strong winds.
Areas at high risk from damage and possible flooding include locations across the provinces of Khammuan, Borikhamxay, Xaysomboun, Vientiane, Xieng Khuang and Luang Prabang.

Authorities of central Borikhamxay province, which borders Khammuan, also warned villagers living along the San and Ngieb Rivers, tributaries of the Mekong, to be on alert for possible flooding following the risingwaters.
Water levels in the rivers continued to rise yesterday and overflowed to flood low-lying areas, authorities said on the province’s website.

The Mekong River water level in Pakxe City of Southern Champassak province yesterday rose to 10.11 metres close to the warning level of 11 metres. It was forecast to rise further to 10.23 and 10.37 metres today and tomorrow respectively.

Pakxe is the only point where the Mekong’s water level rises close to the warning level. The dangerous level in Pakxe is set at 12 metres.
