At 19:00 on 4 June 2026, reporters reported a strong flash flood near Ban Sala Chiang Tong, Sao Hin Subdistrict, Mae Sariang District, Mae Hong Son Province. The Mae Ngae River, which collects water from tributaries including Huai Mae Tob and Huai Mae Song, is flowing rapidly and forcefully as these streams converge.
Mr. Jaruwat Kongbunlap, village headman of Mae Che, Village No. 4, Sao Hin Subdistrict, said he received reports from villagers in Mo Ko Jo that flash floods in Lam Huai Mae Leok were occurring. Consequently, residents were warned to avoid using the route temporarily due to continuously rising water levels.
Meanwhile, Mr. Worasak Panthong, the district chief of Mae Sariang, updated the latest situation, stating that last evening in the Sao Hin–Mae Sariang area, floodwaters have reached Ban Mae Che. Water levels are continuously rising, making roads in the area impassable for all types of vehicles. Water levels are expected to rise further, with the floodwaters likely to flow into the lower area of Ban Pho So.
Residents in risk areas are urged to monitor critical points such as Ban Pho So School, located next to the Mae Ngae River, which recently experienced flash flood damage a few weeks ago, and the temporary Bailey bridge. Extra caution is advised due to concerns that debris could block water flow and damage the bridge.
Authorities ask residents living along the river in risk areas to closely follow updates on the situation. Local leaders and officials are urged to prepare to assist affected residents and coordinate with relevant agencies to ensure immediate support and relief in emergencies. The Mae Sariang District office has ordered related agencies to maintain 24-hour readiness to respond promptly and effectively to aid the public.
