Thunderstorms and haze forecasted across Thailand’s provinces
The Meteorological Department has forecasted thunderstorms in 12 provinces, affecting 20% of the area. Northern Thailand is experiencing high temperatures and haze, with Bangkok expected to reach 38 degrees Celsius (°C) today, March 23.
The low-pressure system over northern Thailand is increasing temperatures due to the weakening high-pressure system covering upper Thailand. This results in hot and hazy daytime conditions but cooler mornings, especially in northeastern regions. Meanwhile, southwesterly winds in the north are causing isolated thunderstorms.
Moderate easterly winds are affecting the Gulf of Thailand, the South, and the Andaman Sea, leading to isolated thunderstorms in the southernmost provinces. The lower Gulf of Thailand experiences moderate waves of 1 to 2 metres, while the upper Gulf and Andaman Sea have waves around 1 metre. During thunderstorms, waves can exceed 2 metres.
Forecasts for the day, from 6am today until 6am tomorrow, indicate hot and hazy conditions during the day in the north, with isolated thunderstorms, mainly in Mae Hong Son, Chiang Mai, and Chiang Rai. The lowest temperatures range from 19 to 23°C, and the highest from 33 to 39°C, with southwesterly winds at 10 to 15 kilometres per hour (km/h).
In the northeast, mornings remain cool with hot and hazy afternoons. Temperatures range from 16 to 21°C at the lowest and 34 to 36°C at the highest, with northeasterly winds at 10 to 20 km/h. Central Thailand experiences hot and hazy conditions, with temperatures ranging from 21 to 24°C at the lowest and 36 to 38°C at the highest, and easterly winds at 10 to 20 km/h.
Eastern regions are also hot and hazy, with temperatures between 22 and 25°C at the lowest and 34 to 37°C at the highest, and easterly winds at 15 to 30 km/h. The sea has waves around 1 metre high.
