Thailand will see morning fog and changeable conditions today, February 16, as a weak high-pressure system continues to cover the north, the northeast and the South China Sea, according to the Thai Meteorological Department (TMD).

Cool mornings are forecast in the North and Northeast, while isolated thundershowers are expected in the Central region, including Bangkok and surrounding areas, as well as in the East.

Easterly and southeasterly winds are prevailing over the Gulf of Thailand and the South, while the northeast monsoon continues over the Gulf, the South and the Andaman Sea, bringing more rain to the South. In the lower Gulf, waves are expected to reach 1 to 2 metres, rising above 2 metres during thundershowers.

In Bangkok and the surrounding areas, light fog is expected in the morning, with isolated thundershowers forecast later. Minimum temperatures will be 25 to 26 degrees Celcius (°C), with highs of 34 to 36°C. Southeasterly winds will blow at 10 to 20 kilometres per hour (km/h).

The TMD said that on February 15, the weak high-pressure system covered upper Thailand and the South China Sea, bringing morning fog. Cool mornings were forecast in the North and Northeast, while isolated thundershowers were expected in the Central region, including Bangkok and surrounding areas, and in the East.
