The Thai Meteorological Department has issued a warning about significant rainfall due to monsoons affecting 51 provinces in Thailand, including Bangkok, with approximately 70% of these regions expected to experience heavy downpours. This warning, which was issued on September 18, predicts that continuous rainfall will persist for the next 24 hours because of a moderate monsoon trough moving through the northern and upper northeastern areas.
The monsoon is converging with a low-pressure zone along the northern coast of Vietnam, coupled with a moderate southwest monsoon covering various regions, such as the Andaman Sea, lower northeastern region, central region, eastern region, southern region, and the Gulf of Thailand. Consequently, this will result in ongoing precipitation, including heavy rainfall in specific parts of the northern, northeastern, and central regions, including Bangkok and its surroundings.
The public is strongly advised to exercise caution in light of heavy rainfall and the potential for accumulating rain, which could lead to flash floods and runoff, especially in areas adjacent to mountain slopes, water bodies, and low-lying regions. Additionally, individuals should take precautions when traveling through areas experiencing thunderstorms.
The northeastern region has a 70% likelihood of thunderstorms, and heavy rain is expected in certain areas, primarily in the provinces of Loei, Nong Khai, Bueng Kan, Nong Bua Lam Phu, Udon Thani, Sakon Nakhon, Nakhon Phanom, Mukdahan, Amnat Charoen, and Ubon Ratchathani. Temperature ranges from 23 to 25 degrees Celsius at the lowest and 29 to 34 degrees Celsius at the highest. Winds will vary in speed from 10 to 20 km/h.
