Heavy overnight rain (113 mm) sent flash water from Khun Mae Bong and Huai Chang into villages in Chok Chai subdistrict, Doi Luang district, Chiang Rai. Flood water about 1 m deep blocked small cars in some villages; the road to Wiang Chiang Rung was flooded. Authorities urge residents along the Bong river and low-lying areas to move valuables and vehicles to high ground, and to evacuate elderly, bedridden and vulnerable people. Relief centres are open 24 hours, and sandbags are available at the Chok Chai subdistrict office. No damage totals or casualties reported yet. If you have stock, a vehicle or a workshop in the Bong river corridor (Chiang Rai to Chiang Saen, via the Kok river), move it now and check your supply routes.
