CHIANG RAI – Heavy rainfall triggered severe flash floods across the highland areas of Chiang Rai Province on August 10, 2026. The disaster began late at night on August 9, at around 10:00 PM. Torrents of water quickly flooded Jokko Village in the Tab Tao Subdistrict. Panicked residents rushed to move their families and belongings to higher ground in the dark.
A sudden power outage and internet blackout made the crisis much worse. These failures disrupted local communication networks, making it impossible to send emergency alerts. Because they received no warning, many villagers lost valuable property. Cars, motorcycles, and household goods were quickly swallowed by the rising floodwaters.
Key Takeaways
- Sudden Flooding: Late-night flash floods hit Jokko Village on August 9, spreading rapidly due to heavy rainfall.
- Blackout Danger: Power and internet failures stopped emergency alerts, leading to severe property and vehicle damage.
- Ongoing Threat: Waters are moving toward the Mekong River, and a damaged bridge poses risks to travelers.
After hitting the highlands, the massive volume of water flowed down into the plains. The floodwaters hit houses in Ban Pa Jee Tai in the Hongao Subdistrict. Families in the Thoeng District had to move their belongings in the middle of the night. The runoff then poured into the Nong Ngao River, leaving a trail of damage behind.
Floodwaters Sweep Into Downstream Villages
The situation remains dangerous as the water heads toward the Mekong River. Continuous rain and thick rain clouds mean officials are closely monitoring the area. Local authorities are urging everyone in the path of the water to stay alert. You can check the Thai Meteorological Department for the latest weather updates.
The rushing water caused serious structural damage to local roads and infrastructure. The bridge over the Nong Ngao River in Lao Village was badly damaged by the current.
