Bangkok: The Meteorological Department has issued a warning for residents in the provinces of Mae Hong Son, Chiang Mai, Chiang Rai, Phayao, Nan, Nong Khai, and Bueng Kan, urging them to prepare for heavy rain that could lead to flash floods and mudslides. The alert extends to Bangkok and its surrounding areas, where thunderstorms are expected to affect 60 percent of the region.
According to Thai News Agency, the forecast predicts continued thunderstorms and heavy rain across Thailand over the next 24 hours. The affected regions, particularly the northern provinces and Bangkok, are advised to stay vigilant due to the risk of flash floods and forest runoff. The weather conditions are attributed to a monsoon trough that spans the upper North, upper Laos, and into a low-pressure area in northern Vietnam, combined with a strong southwest monsoon impacting the Andaman Sea, Thailand, and the Gulf of Thailand.
The maritime conditions are also a concern, with the upper Andaman Sea experiencing strong waves reaching heights of 2-3 meters, and even higher in stormy areas. The lower Andaman Sea has waves around 2 meters high, while the upper Gulf of Thailand sees waves between 1-2 meters. During thunderstorms, these waves can exceed 3 meters. Sailors in these regions are advised to navigate cautiously and avoid areas experiencing thunderstorms. Small boats in the upper Andaman Sea are recommended to stay ashore.
In Bangkok, temperatures are forecasted to range between 24-26 degrees Celsius at the minimum and 33-36 degrees Celsius at the maximum, with the potential for localized heavy rain.
