Thailand braces for cooler temperatures and heavy rain
Thailand is experiencing fluctuating weather patterns, leading to temperatures dropping by 2 to 4 degrees Celsius (°C) in the northern and northeastern regions. Meanwhile, heavy rain is expected in parts of the central, eastern, and southern areas, with high waves in the Gulf of Thailand and the Andaman Sea.
The Meteorological Department of Thailand (TMD) issued a forecast for the next 24 hours, noting that a weak high-pressure or cold air mass is covering the upper northern and northeastern regions. This condition continues to bring chilly mornings to these areas.
At the same time, a low-pressure system near the central coast of Vietnam, combined with westerly and northeasterly winds in the lower central and eastern regions, is causing thunderstorms and heavy rain in some parts of the upper country and the south.
The forecast for today, October 31, until tomorrow morning for the northern region includes cool mornings in the upper part with rain in 10% of the area, mainly in Mae Hong Son, Tak, Phitsanulok, and Phetchabun provinces.

In the northeastern region, cool mornings are expected in the upper part, with thunderstorms in 10% of the area, mostly in Loei, Chaiyaphum, and Nakhon Ratchasima provinces.

The central region will see thunderstorms in 20% of the area, particularly in Kanchanaburi, Lopburi, Saraburi, Nakhon Pathom, Ratchaburi, Samut Songkhram, and Samut Sakhon provinces.
