The Thai Meteorological Department has issued a severe weather advisory covering 43 provinces in Thailand, warning of persistent heavy rainfall affecting approximately 80% of the northern and northeastern regions, including Bangkok. This sudden downpour carries the potential for flash floods and forest runoffs.
The storm’s origin is traced to a robust monsoon trough traversing Myanmar, the upper regions of northern Thailand, and the upper areas of Laos, converging with a low-pressure system in northern Vietnam and the Gulf of Tonkin. This weather pattern is expected to result in significant to extremely heavy rainfall across parts of the northern, northeastern, central, and eastern regions. Residents in these areas are strongly urged to exercise caution due to the risks associated with heavy and accumulating precipitation, which may lead to sudden flash floods and forest runoffs, especially in proximity to slopes, waterways, and low-lying regions. Extra care is advisable when traveling through areas experiencing thunderstorms during this period.
The northeastern region will additionally experience thunderstorms covering around 80% of the area, with substantial to exceptionally heavy rainfall anticipated in specific locales, notably in provinces such as Loei, Nong Khai, Bueng Kan, Nong Bua Lamphu, Udon Thani, Sakon Nakhon, Nakhon Phanom, Kalasin, Mukdahan, Amnat Charoen, and Ubon Ratchathani. Temperature-wise, the minimum will hover between 23-25 degrees Celsius, while the maximum is expected to reach 28-32 degrees Celsius. The prevailing southwestern wind will blow at speeds ranging from 10 to 25 kilometers per hour.
