Heavy rain and rough seas forecast for Thailand as monsoon strengthens and typhoon Ragasa downgrades


BANGKOk: The Thai Meteorological Department reported on Thursday (sEPT 25)that the monsoon trough stretches across northern and northeastern Thailand, while a moderate to rather strong southwest monsoon prevails over the Andaman Sea, the South, Thailand’s Central region, the East, and the Gulf of Thailand.

Isolated heavy to very heavy rainfall is expected in northern and northeastern areas, while scattered thundershowers may occur in the South.

Residents in the upper regions are advised to take precautions, as accumulated rainfall could lead to flash floods and river overflows, particularly along foothills, waterways, and low-lying areas.

Sea conditions:

Upper Andaman Sea: waves 2-3m high, exceeding 3m during thundershowers. Small boats should remain ashore until Sept 26.

Lower Andaman Sea and upper Gulf: waves around 2m, rising above 2m in thundershowers. All vessels should navigate with caution and avoid thundershowers.

Typhoon update:

Typhoon Ragasa, now downgraded to a severe tropical storm, is currently over southern Guangdong, China, and is expected to move into northern Vietnam today. The storm is forecast to weaken rapidly due to the extension of China’s high-pressure system on September 25-26.

The storm is not expected to affect Thailand, but its presence will strengthen the monsoon trough and the southwest monsoon, resulting in increased rainfall and wind activity across the country on Sept 25-26. - The Nation/ANN
