Key Takeaways
- Heavy rainfall is expected across Thailand, particularly in Pattaya, Phuket, and Bangkok.

Weather Forecast and Warnings
The Meteorological Department has reported that the monsoon trough will shift over the upper northern region and upper Laos, moving into a low-pressure area over northern Vietnam and the Gulf of Tonkin. This, combined with moderate southwest monsoon winds covering the Andaman Sea, Thailand, and the Gulf of Thailand, will result in increased rainfall and heavy rain in some areas.
Residents in the eastern region should be particularly cautious of very heavy rain and accumulated rainfall, which may lead to flash floods and water runoff, especially in mountainous areas near waterways and low-lying areas. Travelers should exercise caution when passing through areas experiencing thunderstorms.
