On May 26, it was reported that Doi Suthep–Pui National Park has closed several tourist attractions, including Mae Sa, Tat Mok, and Mok Fa waterfalls, due to heavy rainfall and rising flash flood risks.
At Huai Nam Dang National Park, hot spring areas have been closed from May 26 to May 31, 2025, or until conditions improve. Updates will be provided via the park’s official Facebook page.
Ob Khan National Park also announced a temporary closure of its site and overnight stays. As of 10:00 AM today, water levels at the park headquarters have returned to yesterday morning’s high levels due to overnight downpours in Samoeng District, which recorded 80 mm of rain. Residents along the Khan River from Ban Huay Thong downstream are being warned of rising water levels.
In Chiang Mai city, continuous overnight rain caused localized flooding in low-lying areas such as Sripingmuang, Kad Pratu Kom, and underpasses, prompting the installation of pumps to clear the roads. The Ping River at Nawarat Bridge rose to 2 meters this morning, still below the 3.70-meter critical threshold.
