Northern Thailand Braces for Flash Floods

Northern Thailand faces severe flash floods and landslides as authorities issued an urgent weather warning. The National Water Resources Office (ONWR) advises communities to prepare for dangerous conditions expected from July 2 to July 4, 2026.

A heavy monsoon trough combined with strong southwestern winds is bringing intense rainfall and massive cloud formations to the region. This has caused river levels to reach critical points, with the Sai River posing a significant risk of bursting its banks and flooding nearby homes.

Residents in low-lying areas are advised to move valuables to higher floors and avoid flooded roads. Those in mountain foothills must stay vigilant for potential mudslides triggered by saturated soil and ongoing downpours. Local emergency teams are stationed in high-risk zones.

Government agencies are coordinating rescue operations, distributing emergency supplies, and preparing temporary shelters. Disaster prevention units are also working to clear drains to expedite floodwater recession. Travelers planning visits to Chiang Rai or Phayao this weekend are advised to consider delaying their trips due to hazardous road conditions.
