Bangkok: The Meteorological Department has issued a warning indicating that certain areas in the North, Northeast, East, and South of Thailand are likely to experience heavy rainfall, which could result in flash floods and forest runoff.
According to Thai News Agency, the department's forecast for the next 24 hours suggests that these regions should be on high alert due to potential dangers associated with heavy and accumulated rainfalls. The adverse weather conditions are attributed to a low-pressure cell over northern Vietnam and a moderate southwest monsoon affecting the Andaman Sea, Thailand, and the Gulf of Thailand.
Maritime conditions are also a concern, with moderate waves expected in the Andaman Sea and the Gulf of Thailand. The upper Andaman Sea could see waves reaching about 2 meters, while the lower Andaman Sea and the upper Gulf of Thailand may experience waves between 1 and 2 meters. In regions experiencing thunderstorms, wave heights could exceed 2 meters. Sailors are advised to exercise caution and avoid navigating through areas prone to thunderstorms.
Additionally, Typhoon 'Danas,' currently in the Taiwan area, has been downgraded to a severe tropical storm and is projected to make landfall in China between July 8-9, 2025. While this storm will not directly impact Thailand, it is expected to intensify the southwest monsoon affecting the region.
The regional weather forecast for July 7, 2025, highlights varying levels of thunderstorms and temperature ranges across different parts of the country. In Bangkok and surrounding areas, thunderstorms are expected in 60% of the area, with temperatures fluctuating between 26-34 degrees Celsius. The northern region faces a higher likelihood of thunderstorms, with 70% of the area affected, particularly in provinces such as Mae Hong Son and Chiang Mai.
In the northeastern region, similar conditions are expected, with heavy rain forecasted in provinces including Loei and Nong Khai. The central region, including provinces like Lop Buri and Saraburi, is likely to experience thunderstorms in 60% of the area. The eastern region, particularly in Nakhon Nayok and Prachin Buri, is expected to see heavy rain in some areas.
The southern region's east coast will have thunderstorms in 40% of the area, while the west coast expects 60% coverage with possible heavy rain in provinces like Ranong and Phang Nga. Temperatures in these southern areas will range from 23 to 35 degrees Celsius, with varying wind speeds and wave heights depending on the specific location and weather conditions.
