Flooding in Chiang Rai is beginning to return to normal conditions as officials rush to repair damaged spots. Meanwhile, riverside residents in Mae Sai remain closely vigilant despite repairs and reinforcement of big bag flood barriers around the area.
At 11:00 a.m. on 1 Jul 2026 GMT+7, reporters updated on the flash flood and flash flood situation in Chiang Rai Province. Overall, many areas are starting to improve, but related agencies continue to warn residents to stay alert.
The flash flood at Ban Huai Yen, Moo 7, Rim Khong Subdistrict, Chiang Khong District, caused damage to about 20 homes and temporarily closed traffic on the Chiang Khong-Chiang Saen route (near the entrance to Wat Thep Nimit at kilometers 80-82). As of this morning, the situation has eased and returned to normal. Mud and debris have been cleared, allowing small vehicles to travel freely.
The 4th Hydrology Unit in Chiang Saen, Water Resources Office 1, Department of Water Resources, issued a report stating that at 3:50 a.m., the early warning station in Wiang Pang Kham Subdistrict, Mae Sai District, recorded 102.0 millimeters of rainfall accumulation over 12 hours.
Additionally, radar from the Meteorological Department still detects rain cloud clusters and continuous rainfall in the area, posing a high risk of repeated flash floods. Residents in high-risk zones are urged to prepare accordingly.
Regarding flood prevention progress in Mae Sai District, along the Mae Sai riverbank from Ban Tham Pha Chom to the Second Thai-Myanmar Friendship Bridge, the 3rd Development Division, together with the 37th Military Circle, local administration, and local government organizations, have completed reinforcing big bag barriers and repairing flood defenses. These barriers are high enough to withstand flash floods, reassuring local residents.
However, riverside communities like Ban Tham Pha Chom, Ban Ko Sai, and Ban Pha M Khwai continue their normal lives but prepare by moving belongings to higher ground. At Ban Ko Sai, adjacent to the First Mae Sai Bridge, homes slated for demolition are now unoccupied as owners have locked up and relocated outside for safety. Some areas still experience waterlogging after heavy rains due to slow drainage, with officials working to pump out the water.
Moreover, at Ban Pang Kha Bridge in Tab Tao Subdistrict, the bridge pier has been damaged by water erosion. Officials are currently on-site to expedite repairs and restore the bridge's functionality as soon as possible.
