Thunderstorms forecast for 40 provinces with Bangkok hardest hit

The Thai Meteorological Department (TMD) forecasts thunderstorms for 40 provinces tomorrow, with Bangkok expected to be the hardest hit at 70%. The southern region is on alert for potential flooding, while the upper part of Thailand will experience cool weather in the morning.

TMD issued a 24-hour weather forecast, stating that a high-pressure system or cool air mass is currently weakly covering the upper northern and northeastern regions of Thailand. This condition will result in cool mornings in these areas. Meanwhile, an easterly wind is bringing moisture from the South China Sea and the Gulf of Thailand, affecting the lower northeastern, central, Bangkok and its vicinity, and eastern regions.

This weather pattern will cause heavy rain in some areas of the lower central region, including Bangkok and its vicinity, and the eastern region. Residents in the upper part of Thailand are advised to take care of their health due to changing weather conditions.

TMD has also provided a 10-day weather forecast, indicating the transition from the rainy to the cold season with thunderstorms and cool weather. The Department of Mineral Resources has named 14 provinces in the central and southern regions at risk of landslides and flash floods from tomorrow to October 12

The monsoon trough passing through the upper southern region is causing heavy rainfall in some areas of the south. Residents in these areas should be cautious of heavy and accumulated rainfall, which could lead to sudden flooding and flash floods, especially in foothills near waterways and low-lying areas.

Additionally, the seas in the Andaman Sea and the Gulf of Thailand will have weak winds, with waves below 1 metre high, but more than 1 to 2 metres high in areas with thunderstorms. Mariners are advised to avoid sailing in thunderstorm areas.
