Chilly air mass blankets northern Thailand with heavy rainfall warnings for the south

Today’s weather forecast in Thailand saw a chilly air mass sprawling across the upper part of the country, with temperatures dipping to a frigid 7 degrees Celsius at the peak of the mountain ranges. The Meteorological Department of Thailand (TMD) issued a warning for heavy rainfall in some areas of the southern region.

A high-pressure system or cold air mass is currently spreading over the northeastern region and the South China Sea. Concurrently, the upper northern region is under the influence of westerly winds. Such conditions have resulted in chilly to cold weather in the morning in the northeast, while the north, central, east, and upper southern regions experience cool weather in the morning.

In the mountainous areas of the north, cold to very cold weather persists, with the lowest temperature ranging from 7 to 11 degrees Celsius. The peak areas of the northeast experience cold weather, with the lowest temperature between 11 and 14 degrees Celsius. The public is advised to take care of their health due to the ongoing cold weather in the morning.

Meanwhile, the moderate northeast monsoon is covering the Gulf of Thailand and the south, leading to heavy rainfall in some areas of the lower southern region. People in the lower southern region are warned to be cautious of dangers from heavy rainfall and accumulated rain that could lead to sudden flooding and forest runoff, especially in areas near mountain slopes, waterways, and low-lying areas.

The wave and wind conditions in the Gulf of Thailand and the Andaman Sea are moderate. In the lower Gulf of Thailand, the sea has waves up to 2 metres high, while the upper Gulf of Thailand has waves 1 to 2 metres high. In areas with thunderstorms, the waves are over 2 metres high.

The Andaman Sea has waves approximately 1 metre high, with waves over 1 metre in areas with thunderstorms and away from the coast. Boat operators in these areas are advised to navigate with caution and avoid areas with thunderstorms.

Dust particles

Dust particles are predicted in the central region, including Bangkok and its vicinity. There will be a moderate to quite high accumulation of dust particles/smog due to the weakening wind covering the areas, and poor air ventilation, reported KhaoSod.
