The Thai Meteorological Department (TMD) has issued a warning about severe thunderstorms affecting 41 provinces today. The northern and northeastern regions are anticipated to bear the brunt of these storms, with approximately 80% of these areas expected to encounter heavy rainfall. This heavy rainfall could potentially result in sudden flooding, posing a significant risk to residents, especially those residing in mountainous regions, near waterways, and in low-lying areas. Even the capital city of Bangkok is not immune to these weather conditions.
This meteorological situation arises from a moderate monsoon trough moving over the northern region and upper Laos, intersecting with a low atmospheric pressure trough over upper Vietnam. Concurrently, a moderate southwest monsoon prevails over the Andaman Sea, Thailand, and the Gulf of Thailand. These weather patterns continue to generate thunderstorms and heavy rainfall in certain areas.
The TMD advises residents in the affected regions to exercise caution due to the potential hazards associated with heavy and accumulated rainfall, which can lead to sudden floods and runoff in forested areas. Residents in areas situated on slopes near waterways and low-lying regions should also be vigilant while traveling during periods of thunderstorms. Additionally, in the Andaman Sea and the upper Gulf of Thailand, wave heights are expected to reach 1-2 meters, and in thunderstorm-prone areas, they may exceed 2 meters. Operators of boats in these areas are strongly advised to navigate with care and avoid regions with thunderstorms.
In the northeastern region, approximately 80% of the area is expected to experience thunderstorms, with heavy rainfall in specific provinces such as Nong Khai, Bueng Kan, Nong Bua Lam Phu, Udon Thani, Sakon Nakhon, Nakhon Phanom, Kalasin, Mukdahan, Yasothon, Amnat Charoen, and Ubon Ratchathani. Temperature ranges from 23-25 degrees Celsius to 27-34 degrees Celsius, and wind speeds vary between 10-25 kilometers per hour.
