Torrential rain across Chiang Rai province has triggered flash floods in several areas, with the district of Chiang Khong among the hardest hit. Rising floodwaters have damaged homes and infrastructure, with several buildings collapsing into the river after their foundations were eroded.

The worst-affected site was in Ban Thung Na Noi, located within Wiang Subdistrict Municipality, where a garment workshop situated near the Nam Som stream was destroyed. The fast-flowing water undermined the building’s foundations, causing it to collapse into the river.

Local officials conducted an initial inspection and confirmed that, fortunately, no injuries or fatalities occurred in the incident.

Authorities from the local administration and district offices are now on-site to assess the full extent of the damage and coordinate recovery efforts. Residents living near waterways and in low-lying areas have been advised to remain vigilant and to closely follow official updates and warnings as further rainfall is expected.

Emergency teams continue to monitor the situation, with additional rainfall likely to pose further risk of landslides and flooding across the region.
