"Meteorological Department" Issues 7th announcement warning several provinces "Heavy to very heavy rain" May cause flash floods and landslides
5 September 2026 GMT+7Meteorological DepartmentAnnouncement regarding "Heavy to very heavy rain in upper Thailand (effective until 7 September 2026)" The 7th announcement states that from 5–7 September 2026, upper Thailand will experience heavy to very heavy rain in some areas, especially in the northern and northeastern regions. This is due to a monsoon trough passing through the north and upper northeast, combined with a moderate southwest monsoon covering the Andaman Sea, Thailand, and the Gulf of Thailand.
Residents in these areas are advised to beware of dangers from heavy to very heavy rain and accumulated rainfall, which may lead to flash floods and landslides. This is particularly important for areas along the Mekong River basin, foothills near waterways, and low-lying areas. People should avoid traveling through frequently flooded routes, especially lowland areas that may experience short-term flooding.
For safety and to minimize potential impacts, residents are urged to carefully plan their daily activities and travel during this period. The public should monitor updates from the Meteorological Department and can follow information at the department’s website http://www.tmd.go.th or call 0-2399-4012-13 and 1182, available 24 hours.
