Bangkok: Thunderstorms are expected to affect 40-70% of areas throughout Thailand, with heavy rain anticipated in certain regions.
According to Thai News Agency, the Meteorological Department has reported that the Northeastern and Central regions, including Bangkok and its vicinity, along with the Eastern and Southern regions, will continue to experience heavy rain in some areas. This weather pattern is attributed to a monsoon trough moving through the Central, Upper Southern, and Eastern regions, leading into a strong low-pressure area over the South China Sea. Southeasterly winds are currently prevailing over the lower Northeastern, Eastern, and Upper Gulf of Thailand, while a moderate southwesterly monsoon persists over the Andaman Sea, the Southern region, and the Gulf of Thailand.
The department has issued a 24-hour weather forecast, alerting residents in these regions to the potential dangers of heavy and accumulated rain, which could result in flash floods and landslides, particularly on hillsides near waterways and lowlands. In the upper Andaman Sea, waves are expected to be 1-2 meters high, while in the lower Andaman Sea and the Gulf of Thailand, waves will be about 1 meter high. In areas experiencing thunderstorms, waves could exceed 2 meters, prompting mariners to exercise caution and avoid sailing in these conditions.
The regional weather forecast indicates that Bangkok and surrounding areas will see thunderstorms affecting 70% of the region, with heavy rain possible. Temperatures will range from a minimum of 24-25 degrees Celsius to a maximum of 31-33 degrees Celsius, with variable winds between 10-15 km/h.
In the Northern Region, thunderstorms are predicted in 40% of the area, particularly in provinces such as Mae Hong Son, Lamphun, and Lampang. The Northeastern region can expect thunderstorms in 60% of the area, especially in Chaiyaphum and Khon Kaen. The Central region will likely see thunderstorms in 70% of the area, with heavy rain in provinces like Nakhon Sawan and Uthai Thani. The Eastern region is forecasted to experience thunderstorms in 60% of the area, including heavy rain in Nakhon Nayok and Chachoengsao.
In the Southern Region, the East Coast will see thunderstorms in 60% of the area, affecting provinces such as Phetchaburi and Prachuap Khiri Khan. The West Coast is expected to have thunderstorms in 70% of the area, with heavy rain in Ranong and Phang Nga. Sea conditions will vary, with waves reaching higher than 2 meters in areas with thunderstorms, advising caution for maritime activities.
