Cooler weather in north Thailand, rain persists in Bangkok

Weather conditions in Thailand are changing, with cooler temperatures in the north and northeast, while Bangkok and the east continue to experience rain. The Andaman Sea and the Gulf of Thailand face moderate waves. Travellers to the Philippines should check the weather before departing.

The Thai Meteorological Department (TMD) forecasted the next 24 hours from today, October 23, indicating that a high-pressure system or cold air mass from China is now covering the upper northeast and will soon extend to the upper north and lower northeast. A monsoon trough is passing through the lower central region, upper south, and east.

This pattern decreases temperatures in the northeast by one to three degrees Celsius and brings strong winds. Thunderstorms are expected in some areas of the north and east, while heavy rainfall is forecasted in parts of the central and upper south. The public is advised to take care of their health due to these changing conditions.

Moderate waves are expected in the Andaman Sea and the Gulf of Thailand, with wave heights of 1 to 2 metres in the Andaman Sea and about 1 metre in the Gulf of Thailand. In areas with thunderstorms, waves could exceed 2 metres. Mariners in these regions should proceed with caution and avoid sailing in stormy areas.

The tropical storm Trami is currently located over the eastern Philippines and is expected to move into the upper South China Sea between today and tomorrow. Those planning to travel to the Philippines should check the weather conditions before their journey.
