Thailand braces for heavier rain and rough seas as typhoon Bavi tracks past the country today
The Thai Meteorological Department has forecast heavier rain across the country over the next 24 hours, with heavy falls expected in North Thailand, the upper northeast, and East Thailand. The wet weather is being driven by a low pressure area over upper Vietnam combined with a strengthening southwest monsoon over the Andaman Sea, Thailand, and the Gulf of Thailand.
The TMD warned residents in affected areas to watch for flash floods and runoff, particularly in low lying areas and spots near mountain slopes and waterways.
Seas in the Andaman Sea and Gulf of Thailand are also expected to turn rougher. Waves in the upper Andaman Sea could reach 2 to 4 metres, rising above 4 metres in thunderstorm areas, while the lower Andaman Sea and upper Gulf of Thailand can expect waves of 2 to 3 metres, over 3 metres during storms. Sailors have been urged to exercise caution and avoid thunderstorm areas, while residents along the southern west coast should watch for waves breaking onshore. Small boats in the Andaman Sea and upper Gulf of Thailand have been advised to stay ashore until July 15.
Separately, typhoon Bavi is moving over the Pacific Ocean northeast of Taiwan and is expected to make landfall on the eastern coast of China on July 11 and 12. The TMD confirmed the typhoon will not track into Thailand, though it advised anyone travelling to the affected region to check conditions before departure, reported Matichon.
