Thailand braces for tropical storm and cool winds in 24 provinces
The Thai Meteorological Department (TMD) issued a weather warning today, October 24, highlighting heavy rain in 24 provinces and urging vigilance regarding the powerful tropical storm Trami. Northern Thailand will experience cool weather and strong winds, while the southern seas will see high waves.
The weather forecast for the next 24 hours indicates that upper Thailand will have minimal rainfall, though thunderstorms may occur in some areas. In the northeastern and upper northern regions, morning temperatures will be cooler with strong winds.
This weather pattern is attributed to a moderate high-pressure system or cool air mass covering the upper northern and northeastern regions. In contrast, the easterly winds bringing moisture from the South China Sea and the Gulf of Thailand to upper Thailand have weakened.
The monsoon trough passing through the upper southern region will result in continued thunderstorms. The Andaman Sea will experience waves of 1 to 2 metres, and the Gulf of Thailand will have waves approximately 1 metre high, with waves exceeding 2 metres in thunderstorm-prone areas. Mariners in these regions should exercise caution and avoid sailing in stormy areas.
Meanwhile, the powerful tropical storm Trami is currently situated over the upper Philippines and is expected to move into the upper South China Sea today. It is forecasted to approach the southern coast of Hainan Island in China and the central coast of Vietnam between October 26 and 28. Travellers to these areas should monitor the weather conditions before embarking on their journeys.
In the northern region, the upper part will be cool in the morning with 10% of the area experiencing thunderstorms, particularly in the provinces of Chiang Mai, Tak, Kamphaeng Phet, Phitsanulok, Phichit, and Phetchabun. Temperatures will range from 21 to 24 degrees Celsius (°C) at their lowest to 32 to 35°Cat their highest, with easterly winds blowing at 10 to 15 kilometres per hour (km/h).
