Hot day and thundershowers forecast for most of Thailand

Southerly and southeasterly winds bringing moisture from the South China Sea and the Gulf of Thailand the cause of thunderstorms in some areas

The North, Northeast, Eastern and Central regions including Bangkok will experience a hot day and isolated thunderstorms on Friday, the Thai Meteorological Department said this morning.

These conditions are due to the southerly and southeasterly winds bringing moisture from the South China Sea and the Gulf of Thailand to the upper country, the department said.

It urged people to take care of their health due to the changing weather and beware of severe conditions. Farmers should take precautions to protect crops and animals from potential damage.

Meanwhile, the moderate northeast monsoon over the Gulf, the South and the Andaman Sea will bring thunderstorms to the South. Waves in the Gulf are 1-2 metres high and above 2 metres in storms.  All ships should proceed with caution and keep away from thunderstorms, the department warned.The department added that from Sunday to Tuesday (February 23-25), the moderate to rather strong high-pressure system from China will extend to the Northeast of Thailand, while the westerly trough from Myanmar will move through the North, the Northeast and upper Laos.

These conditions will result in hot days with thunderstorms, gusty winds, hail and lightning strikes in some areas of the upper country, while the South will experience isolated heavy to very heavy rains. Waves in the lower Gulf are likely to rise to 2-3 metres high and above 3 metres in thunderstorms during this period, the department said.
