CHIANG RAI – The Thai Meteorological Department (TMD) has issued a severe weather alert for northern and Northeastern Thailand due to Tropical Storm Kajiki, which intensified from a tropical depression in the upper South China Sea.
The storm is expected to bring heavy to very heavy rainfall and strong winds across northern and upper northeastern Thailand from August 25–27, 2025. Kajiki is forecast to make landfall in northern Vietnam and upper Laos on August 25–26, weakening into a tropical storm and later a depression as it moves toward Thailand’s Nan province by August 26.
Affected northern provinces include Nan, Chiang Rai, Phayao, Chiang Mai, Mae Hong Son, Lamphun, Lampang, Phrae, and Uttaradit, with Nan at high risk of flash floods and landslides, potentially receiving up to 200mm of rain.
Residents are urged to prepare for severe weather, flash floods, landslides, and transport disruptions, particularly in low-lying and mountainous areas.
