Chilly blast hits Thailand as monsoon brings storms south

A cold spell is sweeping across Thailand as a powerful high-pressure system brings strong winds, falling temperatures and stormy seas to several regions.

A strong high-pressure system from China is extending over upper Thailand, triggering a cold snap across the north, northeast, and parts of the south. Morning temperatures are dipping sharply, particularly in northern regions, where residents woke up to icy winds and a drop of 1 to 2°C.

The Meteorological Department (TMD) is advising people in these regions to stay warm and take care of their health. The combination of dry air and gusty winds also raises the risk of fires, while farmers are being urged to protect crops from the cold snap.

Meanwhile, the northeast monsoon is picking up over the Gulf of Thailand, the south, and the upper Andaman Sea. This is being compounded by a low-pressure system hovering over the lower Gulf, causing widespread thundershowers and isolated downpours, especially in southern provinces.

The forecast for 6am today, November 20, to 6am tomorrow, November 21, is as follows:

In northern Thailand, temperatures are expected to range from 14 to 21°C during the night and early morning, climbing to 23 to 29°C later in the day. Mountainous areas will be especially cold, with lows between 3 and 11°C. Winds are coming in from the northeast at 10 to 25 km/hr.

In the northeast, temperatures will drop to between 15 and 18°C at night and peak between 26 and 29°C during the day. Mountainous zones will see lows between 6 and 12°C. Winds are stronger here, blowing at 15 to 40 km/hr.
