Heavy rainfall is expected across Thailand, with over 60% coverage in all regions, including Bangkok.

Key Takeaways
- Heavy rainfall expected across Thailand, including Bangkok.
- Potential for flash floods and forest runoff.
- Strong winds and high waves in the Andaman Sea and Gulf of Thailand.
- Residents advised to stay informed and exercise caution.
Weather Forecast and Warnings
The TMD has forecasted that the southwest monsoon covering the Andaman Sea, Thailand, and the Gulf of Thailand is relatively strong. This, combined with a monsoon trough passing through northern Thailand and upper Laos, leading to a low-pressure area over northern Vietnam, is causing significant rainfall in many areas of the country.
Thailand will experience heavy to very heavy rainfall in several regions, particularly in the north, northeast, east, and western parts of the south. Residents in these areas are advised to be cautious of the dangers posed by heavy and accumulated rainfall, which could result in sudden flooding and flash floods, especially in foothill areas near waterways and lowland regions.
