TMD sounds the ‘rain’ alarm as monsoon hits 28 provinces

The latest weather conditions have prompted the Thai Meteorological Department (TMD) to issue a warning for severe monsoon rains affecting 28 provinces across Thailand, including Bangkok. The capital is expected to experience intense rainfall covering 40% of the area, requiring residents to exercise caution.

Throughout the northern and northeastern regions of Thailand, cooler temperatures and morning fog are anticipated. Residents are advised to take care of their health due to the fluctuating weather conditions and exercise caution when travelling in foggy areas. Farmers should also prepare to protect their crops from potential rain-induced damage during this period.

The eastern and southeastern winds are bringing moisture from the South China Sea and the Gulf of Thailand, affecting the lower northeastern, eastern, and central regions, including Bangkok and its vicinity, as well as the upper southern region. Meanwhile, a high-pressure system or cool air mass covering the north and upper northeast is weakening.

The northeastern monsoon, also weak, is sweeping over the Gulf of Thailand and the southern region, resulting in isolated thunderstorms in the south. In the Gulf of Thailand and the Andaman Sea, waves are generally low, not exceeding 1 metre, but may rise above 2 metres in stormy areas. Mariners are advised to avoid sailing in areas with thunderstorms.

The weather forecast for Thailand from 6am today until 6am tomorrow indicates that the northern region will experience cool weather with morning fog. A slight increase in temperature is expected, with isolated light rain mainly in the upper parts.

The lowest temperatures range from 20 to 23 degrees Celsius, while the highest are between 33 and 36 degrees Celsius. On mountain peaks, conditions will be cool to cold, with temperatures dropping to between 10 and 16 degrees Celsius. The northeast wind is expected to blow at speeds of 10 to 15 kilometres per hour.
