Rain reigns: TMD warns 27 provinces, including Bangkok, to brace for heavy rainfall
The Meteorological Department of Thailand (TMD) issued a heavy rainfall warning for 27 provinces, including Bangkok. The southern region is expected to receive significant rainfall, covering 80% of the area, which may lead to sudden flooding and runoff.
A high-pressure system from China is covering the northern region, the northeastern region, and the South China Sea. This system is bringing in moisture from the South China Sea and the Gulf of Thailand, resulting in rainfall in the upper part of Thailand. Citizens in the upper part of Thailand are urged to take care of their health due to the changing weather conditions. Farmers are also advised to prepare for potential damage to agricultural products.
The northeastern monsoon, covering the Gulf of Thailand and the southern region, is moderate. This results in heavy rainfall in some areas of the lower southern region. Sea waves in the lower Gulf of Thailand are moderate with a height of about 2 metres. In areas with thunderstorms, the waves can be more than 2 metres high.
The upper Gulf of Thailand has waves of 1-2 metres high and in areas with thunderstorms, the waves can be more than 2 metres high. The Andaman Sea has waves of about 1 metre high, with waves of 1-2 metres high away from the coast. In areas with thunderstorms, the waves can be more than 2 metres high.
People in the lower southern region are asked to be cautious of heavy rainfall and accumulated rain, which may cause sudden flooding and runoff, especially in areas near mountain slopes, waterways and low-lying areas. Boat operators should navigate with caution and avoid sailing in areas with thunderstorms.
The northern region will have cool weather in the morning with light rain in some areas. The lowest temperature is 18-22 degrees Celsius and the highest temperature is 32-34 degrees Celsius. The mountain tops are cold with a minimum temperature of 9-15 degrees Celsius.
