BANGKOK — 1 July 2026, Thailand’s Department of Mineral Resources has warned of possible landslides and flash floods in 13 provinces over the next two to three days due to persistent heavy rain.
The Department’s Geohazard Operations Center issued the alert, urging its volunteer monitoring network and residents in at-risk areas to remain vigilant between 1–3 July 2026.
The provinces under the warning are Mae Hong Son, Chiang Mai, Chiang Rai, Tak, Nan, Phitsanulok, Chanthaburi, Trat, Ranong, Phang Nga, Phuket, Krabi and Trang.
The department said a monsoon trough stretching across northern Thailand and the upper Northeast, combined with a strengthening southwest monsoon over the Andaman Sea, Thailand and the Gulf of Thailand, is expected to bring continued heavy rainfall.
Rainfall has already exceeded 100 millimetres in some areas over the past 24 hours, with flash floods beginning in several locations, increasing the risk of landslides.
Authorities have instructed geohazard monitoring volunteers to closely monitor rainfall, remain on alert, warn local communities of any landslide or flash flood threats, notify relevant agencies and follow established emergency response plans.
