Thailand braces for heavy rain and strong monsoon impact
The Meteorological Department of Thailand (TMD) forecasts a weakening cold air mass and heavy rain over upper Thailand, though chilly conditions persist, while a strong monsoon affects the south. Yesterday, January 29, six provinces were expected to experience heavy rain.
The strong northeast monsoon affecting the Gulf of Thailand and the southern region is causing high waves, especially in the lower Gulf, where they reach 2 to 3 metres. Thunderstorms can increase wave heights beyond 3 metres.
In the upper Gulf, waves are around 2 metres, and in the Andaman Sea, they range from 1 to 2 metres, with thunderstorm areas experiencing higher waves. Residents along the eastern southern coast should be cautious of coastal waves.
Mariners in the Gulf and Andaman Sea are advised to navigate carefully and avoid stormy areas, with small boats in the lower Gulf advised to remain ashore for another day.
The current weather conditions also affect dust accumulation in upper Thailand, which remains at good to moderate levels due to moderate winds aiding ventilation.
In the north, cool to cold conditions are predicted, with temperatures ranging from 14 to 16 degrees Celsius at their lowest and 26 to 32 degrees Celsius at their highest. Mountain tops will be particularly cold, with lows of 5 to 11 degrees Celsius and some frost expected. Winds are easterly at 10 to 20 kilometres per hour.
Weather forecast
The northeast will experience cold weather, with minimum temperatures between 10 and 15 degrees Celsius and highs from 27 to 30 degrees Celsius. On the mountaintops, temperatures could drop to 5 to 10 degrees Celsius. Winds are from the northeast at 10 to 25 kilometres per hour.
In central Thailand, expect cool mornings with lows of 16 to 20 degrees Celsius and highs of 29 to 31 degrees Celsius. Northeasterly winds will be at 10 to 20 kilometres per hour.
The eastern region will also have cool mornings, with temperatures ranging from 18 to 21 degrees Celsius at their lowest and 29 to 32 degrees Celsius at their highest. Northeasterly winds will reach 15 to 35 kilometres per hour, with sea waves approximately 1 metre high, increasing to 1 to 2 metres offshore.
In the southern region (east coast), the upper part will be cool in the morning with scattered thunderstorms in 10% of the area, particularly in Surat Thani, Nakhon Si Thammarat, Phatthalung, Pattani, Yala, and Narathiwat. Temperatures will range from 20 to 25 degrees Celsius at their lowest to 29 to 34 degrees Celsius at their highest.
From Surat Thani upwards, northeast winds will be 20 to 35 kilometres per hour, with 2-metre-high waves, rising in thunderstorms. From Nakhon Si Thammarat downwards, winds will be 20 to 40 kilometres per hour, with 2 to 3 metre-high waves, increasing in thunderstorms.
The west coast of the south will have cool mornings with scattered light rain, minimum temperatures of 22 to 25 degrees Celsius, and highs of 31 to 35 degrees Celsius. Northeasterly winds will be 20 to 35 kilometres per hour, with sea waves of 1 to 2 metres, increasing offshore and in thunderstorm areas.
Bangkok and its vicinity will see cool morning temperatures between 19 and 21 degrees Celsius, reaching 29 to 32 degrees Celsius during the day. Winds will be from the northeast at 10 to 20 kilometres per hour, reported KhaoSod.
The TMD also provides a 15-day rainfall forecast, updating daily accumulations from 7am to 7am the next day. Between January 29 and February 12, weather patterns are expected to change, with decreasing cold air influence, increased morning fog, and fluctuating winds.
Dust accumulation may rise with weakening winds, while the south should be wary of strong winds for another day before they subside.
