Thailand Weather Update: Heavy Rain in Bangkok and Cold Fronts in the North and Northeast
The Meteorological Department forecasts significant weather changes across Thailand over the next 24 hours. Heavy rainfall is expected in Bangkok and surrounding areas, impacting approximately 60% of the city, with thunderstorms occurring in some regions. Meanwhile, the northern and northeastern parts of the country will experience colder temperatures, dropping by 2-4°C, accompanied by strong winds.
A moderate high-pressure system originating from China is currently influencing the northern and northeastern regions, spreading cold air and leading to a temperature decrease of 1-2°C in the north and 2-4°C in the northeast. This system is also bringing moist east and southeast winds to the eastern, central, and southern areas, including Bangkok.
Residents are advised to be cautious and take health precautions due to the changing weather conditions.
Maritime warnings include moderate winds in the Gulf of Thailand and the Andaman Sea, with waves reaching 1-2 meters; areas experiencing thunderstorms may see waves over 2 meters. Mariners are urged to navigate carefully and avoid stormy waters.
Light to moderate rain is expected today in Phra Nakhon Si Ayutthaya, Pathum Thani, Nonthaburi, Bangkok, and Samut Prakan, primarily between 5:30 PM and 6:00 PM, lasting over an hour as the rain moves westward.
