The Meteorological Department has forecast widespread rain across much of the country on Monday (November 3), with up to a 70% chance of heavy rainfall in Bangkok and nearby provinces due to a strong monsoon trough sweeping through the Central region.
The upper North and upper Northeast regions will continue to experience cool morning temperatures.
Farmers are advised to protect their crops and agricultural produce from excess moisture. The public should stay aware of changing weather conditions and exercise caution when driving in areas affected by rain, as flash floods may occur in some locations.
The strong monsoon trough currently extends across the Central, upper Eastern, and lower Northeastern regions into a low-pressure area along Vietnam’s central coast. A weak high-pressure system covers northern Thailand.
Moderate winds blow over the upper Andaman Sea, with waves reaching 1–2 meters, rising above 2 meters during thundershowers. In the Gulf of Thailand and the lower Andaman Sea, waves are around 1 meter, exceeding 2 meters during storms.
Mariners are urged to proceed with caution and avoid sailing in areas with thunderstorms.
Thunderstorms are expected over about 70% of the area, with isolated heavy rainfall.
Summary: A strong monsoon trough brings widespread heavy rain and thunderstorms to central Thailand, prompting warnings for farmers, motorists, and mariners to take precautions.
