Bangkok: Rainfall is on the rise throughout Thailand, and there is a warning for a potential storm hitting by the end of the month.
According to Thai News Agency, the Meteorological Department has indicated that the country will see increasing rainfall during the latter half of September, especially between September 22 and 25. This surge in precipitation is attributed to the influence of monsoon activity and a developing low-pressure area.
Mr. Somkuan Tonjan, Director of the Weather Forecast Division at the Meteorological Department, has highlighted that from September 16-30, 2025, continuous rainfall is anticipated across Thailand. Particularly from September 22-25, heavy rain is expected, which could lead to flash floods and landslides. The monsoon trough is affecting the central and northeastern regions, while a strengthening southwest monsoon is impacting the southern areas, potentially bringing heavy rainfall to some parts.
The northern, central, and northeastern regions will experience scattered rain along the monsoon trough. The Andaman coast, including Ranong, Phang Nga, and Phuket, will also be under the monsoon's influence. In the southern region on the lower Gulf of Thailand, rainfall is expected to increase, with some areas possibly facing heavy downpours. The low-pressure area anticipated from September 22-25 is likely to bring heavy to very heavy rainfall, especially in the lower Central, Central Northeastern, and low-lying regions where rain accumulation is a concern.
Residents near river basins, flood-prone zones, and hillsides are urged to be cautious of flash floods and accumulating rainwater, and to exercise extra caution while driving in heavy rain conditions. Towards the end of the month, around September 26-27, a storm system may form and move into Thailand. However, the Meteorological Department advises that weather conditions can change, and the public should stay informed through official updates from the department's website and announcements, avoiding reliance on potentially misleading social media forecasts.
