Rising Sai River Levels Prompt Flood Alert in Mae Sai
Authorities have issued an urgent warning for residents in Mae Sai as the Sai River continues to rise, threatening to overflow its banks.
On September 7, 2026, Matichon Online reported that the Department of Disaster Prevention and Mitigation (DDPM) has issued an urgent alert regarding the Sai River in Chiang Rai province. Water levels in the river are rising continuously, prompting officials to warn residents in three sub-districts of Mae Sai to remain vigilant against potential flooding.
Local authorities have advised residents in the affected areas to prepare for possible overflow by moving belongings and valuable items to higher ground. The situation is currently being monitored as the water level approaches the riverbanks.
For travelers and residents in the Mae Sai area, this development is significant as it may impact local transportation, access to riverside businesses, and general safety in low-lying zones. Those currently in the region are encouraged to follow updates from local government channels and exercise caution near the riverbanks.
At this time, it remains to be confirmed how much further the water levels will rise and whether the river will officially breach its banks in the designated sub-districts. No official evacuation orders have been issued as of the latest report, but the situation remains fluid.
