15 Provinces on Alert for Landslides, Flash Floods
Thailand's Geological Disaster Operations Center warns 15 provinces of landslide and flash flood risks through August 1 due to heavy monsoon rains exceeding 150mm daily across the North, Northeast, Central, East and South regions.
On July 30, the Geological Disaster Operations Center of the Department of Mineral Resources under the Ministry of Natural Resources and Environment issued a warning for 1-3 days of heavy rain and heightened risk of landslides and flash flooding across 15 provinces: Tak, Mae Hong Son, Chiang Mai, Lamphun, Chiang Rai, Nan, Phayao, Phrae, Uttaradit, Phetchabun, Kanchanaburi, Chanthaburi, Trat, Ranong, and Phangnga. Monitoring will remain in effect from July 30 through August 1, 2025.
High-risk areas in the North include multiple districts in Tak, Mae Hong Son, Chiang Mai, Lamphun, and Chiang Rai, as well as districts in Nan, Phayao, Phrae, Uttaradit, and Phetchabun. In the Central region, Kanchanaburi faces risks in several districts. The Eastern region includes vulnerable areas in Chanthaburi and Trat. Southern provinces Ranong and Phangnga are also on alert.
The warning is due to a monsoon trough affecting the North and Northeast, combined with strong southwest monsoon winds, producing continuous heavy rainfall exceeding 150 millimeters in 24 hours across affected areas. Cumulative rainfall over several days and early signs of flash flooding in some locations increase the risk of landslides. Network volunteers and the public are urged to monitor conditions continuously, report any incidents immediately, and follow established emergency response protocols.
