Geological Department Warns 11 Provinces of Mudslides, Flash Floods
Thailand's Geological Department warned 11 provinces of mudslide and flash flood risks over July 6-7, with heavy rainfall from Typhoon Maysak and monsoon conditions particularly threatening northern and eastern regions.
The Geological Disaster Operations Center of the Department of Mineral Resources under the Ministry of Natural Resources and Environment has warned of landslide and flash flood risks over the next 1-2 days. The alert covers 11 provinces: Tak, Mae Hong Son, Chiang Mai, Chiang Rai, Phayao, Nan, Uttaradit, Phichit, Phetchabun, Chanthaburi, and Trat between July 6-7, 2026.
The warning specifically targets northern areas including districts such as Um Phang and Mae Sot in Tak Province, and eastern areas including Ko Chang in Trat Province, among numerous other vulnerable districts listed in both regions.
The heavy rainfall is being driven by the influence of Typhoon Maysak and a monsoon trough passing over northern Thailand and Laos, combined with a strengthening southwest monsoon over the Andaman Sea and Gulf of Thailand. This is causing intense rainfall in several areas, particularly in the northern and eastern regions, with rainfall measurements exceeding 100 millimeters in 24 hours. Flash flooding has already begun in some areas and may trigger landslides.
Authorities are requesting volunteer monitoring networks to remain alert, continuously measure rainfall levels, and immediately report any incidents of landslides or flash floods to residents and relevant agencies, following established emergency response protocols.
