Floodwater was reported to be as high as three metres in some parts of the northeastern province. Several areas were submerged, especially Non Sawang and Non Sa-ard communities in tambon Nai Muang of Ban Pai district.

People thronged local roads, waiting for help from authorities after their houses were submerged overnight. Some families were stranded and were waiting on their roofs. Currents were strong and all types of vehicles were submerged.

Suparb Maungsri, 57, of Non Sa-ard, said the floodwater had kept rising since 8pm Friday. As of 10am Saturday, they had received no help.

“My family members and our neighbours have to stay on roofs. We urgent need help," he said. "Boats should be brought to take community people to stay Wat Chanprasit in Ban Pai municipality.

“The hardest hit area are people living in the municipality, as well as Non Swang and Non Sa-ard, totalling 1,000 households.

“This year, the flooded area has expanded, making the deluge the biggest in 40 years."

Ban Pai police later helped people move their belongings from their houses in the municipality and evacuated some of them to dry areas.

Kalasin fares better

In adjacent Kalasin province, heavy downpours caused the Huay Sithon reservoir to overflow, inundating 10 communities in downtown Muang district. About 450 households were affected. The water levels were in a range between 80cm and 1m.

Kalasin governor Kraisorn Kongchalard on Saturday held a meeting with chiefs of all 18 districts and concerned agencies to survey the damage caused by the tropical storm and provide assistance to people.

Mr Kaisorn said most of the affected areas were farmland, houses, bridges and roads. Luckily, the Lampao dam could still hold more water. The dam is now holding 719 million cubic metres of water, or about 41% of its capacity, added the governor.

Jaruwat Boonperm, mayor of Muang municipality, said the water level in municipal areas were about 80cm to one metre high. The municipality has prepared boats to help affected residents evacuate their belongings to dry areas.

Dykes collapse

In Roi Et province, three dykes north of Lampao Dam collapsed, inundating tens of thousands of rice fields, farmland and residential area.

The situation was aggravated by run-off, which converged in Lam Nam Yung in tambon Wang Luang, Selephum district.

In Muang district, floodwater was 60-90cm high. Soldiers were sent to help people move their belongings.
