Mae Sai district in Chiang Rai province faces renewed widespread flooding as the Sai River, swollen by heavy rains in Myanmar's Shan state, breached its banks, impacting commercial areas and communities.
This marks the second flood this year, with officials warning of a potential repeat of last September's severe event, leading to the closure of the Thai-Myanmar Friendship Bridge and patient transfers from the district hospital.
Experts attribute the increasing frequency and severity of flooding to multiple factors, including unusually heavy rainfall, deforestation, extensive mining activities, urban expansion, and the disappearance of natural flood paths.
The flooding extends beyond Mae Sai, with Sukhothai province also experiencing significant inundation as the Yom River overflowed its banks in several districts.
