The Thai Meteorological Department (TMD) has issued a weather warning for August 13, cautioning 38 provinces in Thailand about potential heavy rain affecting 60% of the area, including Bangkok. Residents are advised to remain vigilant against flash floods and forest run-offs as Typhoon Podul is being monitored.
The weather forecast for the next 24 hours indicates thunderstorms and heavy rain in parts of northeast, east, and southwest Thailand. Provinces such as Chanthaburi, Trat, Ranong, and Phang Nga should be particularly cautious of accumulated rainfall that may lead to sudden flooding and overflow of forest streams, particularly in mountainous and low-lying areas.
This is due to a monsoon trough passing over northern Thailand and Laos, reaching a low-pressure area in Laos and northern Vietnam. A moderate southwest monsoon is also covering the Andaman Sea, Thailand, and the Gulf of Thailand.
In the Andaman Sea and upper Gulf of Thailand, moderate waves are expected, with the upper Andaman Sea seeing waves around 2 metres high and even higher during thunderstorms.
The upper Gulf of Thailand and lower Andaman Sea will experience waves of 1 to 2 metres and higher in thunderstorm areas. Mariners are advised to exercise caution and avoid areas with thunderstorms.
Typhoon Podul, located in the Pacific Ocean, is expected to pass through Taiwan and make landfall on the eastern coast of China tonight, but it is not forecast to enter Thailand.
