Huai Fong village in tambon Khun Nan in Chalerm Prakiat district was among the hardest-hit areas as its main road collapsed after being ravaged by flood water for several hours.
32nd Ranger Task Force chief Col Atsawong Ninphan led soldiers to help locals move to safety after soil in the area gave way, destroying or threatening to destroy homes.
An initial inspection found a house collapsing. An electricity pole also fell causing a widespread blackout in the village.
The officers assisted with moving the residents and their belongings to safer areas away from flooded zones.
The situation was becoming dire in some heavily flooded locations, prompting Nan governor Suwat Phromsuwan to order emergency response plans be implemented
