Rain check: heavy downpours set to flood 43 provinces in Thailand
The Thai Meteorological Department (TMD) issued another warning for continuous heavy rainfall impacting 43 provinces, including Bangkok and southern regions, with 70% of the areas affected, posing risks of flash floods.
Today, the TMD forecasted 24-hour weather conditions, noting that easterly winds are bringing moisture from the South China Sea and the Gulf of Thailand to cover the lower northeastern region, the central region, including Bangkok and surrounding areas, and the eastern region. This weather pattern is causing heavy rainfall in some areas of the lower central region, Bangkok, and its vicinity, as well as the eastern region.
Additionally, a weak high-pressure system continues covering the upper northeastern region, resulting in cool morning temperatures. Residents in northern Thailand are advised to take care of their health due to these changing weather conditions, said a TMD spokesperson.
“We urge the public in the northern part of Thailand to maintain their health amidst these fluctuating weather conditions.”
The monsoon trough passing over the upper southern region is leading to very heavy rainfall in some areas. Residents in these regions should be on high alert for potential dangers from very heavy and accumulated rainfall, which could result in flash floods and forest runoff, especially in areas near slopes, watercourses, and low-lying regions.
Meanwhile, the Andaman Sea and the Gulf of Thailand are experiencing weak wind waves, with waves below 1 metre. However, in areas with thunderstorms, waves can exceed 2 metres. Mariners should avoid sailing in areas with thunderstorms.
