Thunderstorm warning for 45 Thai provinces, including 60% of Bangkok: Heavy rain expected

The Thai Meteorological Department today issued a thunderstorm warning for 45 provinces, including 60% of Bangkok. The weather system is sweeping across the northern and northeastern regions, heading towards a low-pressure area over the Bay of Bengal, while a moderately strong southwestern monsoon is blowing across the Andaman Sea, Thailand, and the Gulf of Thailand. This is causing thunderstorms and heavy rainfall in some parts of the northern, northeastern, eastern, and western southern regions.

Residents in the affected areas are warned of potential dangers from heavy to very heavy rainfall and accumulated rainfall, which could lead to sudden flooding and flash floods. This is particularly true for mountainous areas near waterways and low-lying areas. Extra caution is advised when travelling through areas with thunderstorms.

In the upper Andaman Sea and the upper Gulf of Thailand, the wind is moderately strong, causing sea waves to reach 2 to 3 metres high. In thunderstorm areas, the waves can exceed 3 metres. In the lower Andaman Sea, wave height is between 1 to 2 metres. In thunderstorm areas, waves can exceed 2 metres. Boaters in the affected areas are advised to navigate with caution and avoid areas with thunderstorms. Small boats in the upper Andaman Sea and the upper Gulf of Thailand should also remain ashore.

Typhoon ‘Saola’ is currently in the Pacific Ocean, or northeast of the Philippines, and is expected to move into the upper South China Sea between August 30 to September 1. It will then move up to the southeastern coast of China from September 2 to 4. This typhoon will not directly affect Thailand’s weather, but those planning to travel to the affected areas should check the weather forecast before their journey.
