Bangkok: Upper Thailand is expected to continue experiencing heavy rainfall in certain areas, with residents in Mae Hong Son, Chiang Mai, Tak, and Kanchanaburi provinces urged to remain cautious. The Meteorological Department has reported that the ongoing heavy rain is likely to persist in northern, upper northeastern, central, and eastern parts of Thailand.
According to Thai News Agency, the Meteorological Department forecasts that in the next 24 hours, the strong southwest monsoon over the Andaman Sea, Thailand, and the Gulf of Thailand will maintain its strength. This, combined with a monsoon trough passing through northern Thailand, upper Laos, and into a low-pressure cell in northern Vietnam, is contributing to the heavy rains. The public is advised to be aware of the potential dangers such as flash floods, forest runoff, and overflowing rivers, particularly near hillsides, waterways, and low-lying areas.
Marine conditions are also expected to be turbulent, with waves in the upper Andaman Sea and the upper Gulf of Thailand reaching heights of 2-3 meters, and higher in areas experiencing thunderstorms. Sailors are advised to navigate with caution and avoid thunderstorm-prone areas, while small boats should refrain from leaving the shore for another day.
In addition, Typhoon 'Komai' is currently located in the western Philippines and is expected to move towards southern Japan, without impacting Thailand. Meanwhile, regional forecasts indicate varied weather conditions across the country. Bangkok and its surrounding areas will see rain or thunderstorms in 60% of the area, while the northern region anticipates thunderstorms in 60% of the area, with heavy rain particularly in Mae Hong Son, Chiang Mai, Chiang Rai, Lamphun, Lampang, Sukhothai, Tak, and Kamphaeng Phet.
The northeastern region is forecasted to have thunderstorms in 40% of the area, with heavy rain in some provinces, while the central region expects thunderstorms in 40% of the area. The eastern region will experience rain or thunderstorms in 60% of the area, with some provinces receiving heavy rain. Southern regions, both on the east and west coasts, will see rain or thunderstorms in 20% of the area, with varying wind speeds and wave heights depending on the location.
