4 September 2026 GMT+7Meteorological DepartmentAnnouncement regardingHeavy to very heavy rainfall over upper Thailand (effective until 7 September 2026 GMT+7).In its fifth bulletin (185/2569), the Meteorological Department states that from 4 to 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 crossing 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 be cautious of heavy to very heavy rain and accumulated rainfall, which may cause flash floods and mudslides. Particularly vulnerable are areas along the Mekong River basin, foothills near waterways, and low-lying areas. Avoid traveling through repeatedly flooded routes, especially in low-lying zones prone to short-term flooding.
Meanwhile, Tropical Depression Sodel in Guangdong Province, China, has weakened into a strong low-pressure area.
For safety and to minimize potential impacts, the public is urged to plan daily activities and travel carefully during this period.
