Bangkok braces for thunderstorms as cool spell hits northern Thailand
A weather warning has been issued for 30 Thai provinces, including the capital, Bangkok, due to expected thunderstorms affecting 20% of the area. This forecast comes as the northern part of Thailand experiences cool to cold temperatures, while the southern region faces high waves today, January 28.
The Thai Meteorological Department (TMD) forecasted for the next 24 hours that the high-pressure system covering Thailand and the South China Sea is weakening but will continue to bring cool weather in the mornings to the northern and central regions, with the northeast experiencing cold temperatures.
The westerly wind streams from Myanmar are expected to cover the upper parts of the northern, central, and northeastern regions, leading to scattered rainfall in upper Thailand. The public in these areas is advised to take care of their health due to changing weather conditions.
The northeast monsoon over the Gulf of Thailand and the south is weakening but still causes thunderstorms during this period. The lower Gulf of Thailand’s winds are diminishing, with waves about 2 metres high, and where thunderstorms occur, waves can be higher than 2 metres.
In the upper Gulf of Thailand and the Andaman Sea, waves are 1 to 2 metres high, with areas experiencing thunderstorms seeing waves of about 2 metres, and further from the coast, waves higher than 2 metres. Fishermen in the Gulf of Thailand and the Andaman Sea are advised to navigate with caution and avoid areas with thunderstorms, reported KhaoSod.
Regarding dust particles during this period, the upper part of Thailand has seen a reduction in dust and smoke accumulation due to wind coverage.
