Bangkok: The Meteorological Department has issued a warning that certain areas of the Northeast region are expected to experience heavy to very heavy rainfall, while thunderstorms are anticipated throughout Thailand. The warning includes a cautionary note about strong waves, particularly in the upper Andaman Sea and the upper Gulf of Thailand, where wave heights are predicted to reach 2-3 meters and exceed 3 meters during thunderstorms.
According to Thai News Agency, the forecast for the next 24 hours indicates significant rainfall in the Northeast, with potential flash floods and forest runoff, especially in hillside regions near waterways and lowlands. The monsoon trough affecting the lower North and upper Northeast, coupled with a strong southwest monsoon over the Andaman Sea, South, and Gulf of Thailand, is contributing to these weather conditions. Farmers are advised to take necessary precautions to protect their crops from potential damage.
The sea conditions are expected to be challenging, with the upper Andaman Sea and upper Gulf of Thailand experiencing strong waves. Sailors are advised to exercise caution and avoid areas experiencing thunderstorms. Small boats in these regions should remain ashore until June 13, 2025. Additionally, the tropical storm "Wutib" is moving through the upper South China Sea and is expected to affect Hainan Island and southern China between June 13-14, 2025, although it is not projected to impact Thailand directly.
The regional weather forecast highlights varying conditions across different parts of Thailand. In Bangkok and surrounding areas, thunderstorms are expected to cover 60% of the region, with temperatures ranging from a minimum of 26-28 degrees Celsius to a maximum of 33-34 degrees Celsius. The Northern region will experience thunderstorms in 70% of the area, with heavy rain in specific provinces such as Mae Hong Son and Chiang Mai, and temperatures ranging from 23-27 degrees Celsius at night to 34-37 degrees Celsius during the day.
Meanwhile, the Northeastern region anticipates thunderstorms in 60% of the area, with heavy to very heavy rain in provinces including Loei and Nong Khai, with temperatures varying between 23-25 degrees Celsius at night and a daytime high of 30-35 degrees Celsius. The Central and Eastern regions are also expected to experience significant thunderstorms and heavy rain in selected areas, while the Southern regions on both the east and west coasts will see varying degrees of thunderstorms and rainfall.
The public is urged to stay informed about the weather conditions and take necessary safety measures, especially those residing in vulnerable areas prone to flooding and landslides.
