Heavy rain to hit 49 provinces, including Bangkok this evening
The Thai Meteorological Department (TMD) has issued a warning for heavy rainfall across 49 provinces, affecting the northern, northeastern, eastern, southern regions, as well as Bangkok, with 70% of the area expected to experience storms this afternoon and evening.
Weather forecasts for the next 24 hours indicate that a moderate monsoon trough is sweeping through upper northern and northeastern Thailand, moving towards a low-pressure area in upper Vietnam and the Gulf of Tonkin. Additionally, the prevailing southwesterly monsoon continues to cover the Andaman Sea, Thailand, and the Gulf of Thailand. Meanwhile, an easterly and southwesterly wind convergence zone is affecting the upper northeastern region. These conditions are expected to bring heavy rainfall to the northern, upper northeastern, central, eastern, and southern regions, including Bangkok and its vicinity.
Residents in these areas are advised to be cautious of heavy rain and accumulated rainfall that could trigger flash floods and landslides, particularly in foothill regions near waterways and low-lying areas.
The TMD has specifically warned that 48 provinces across four regions, including Bangkok, will be heavily impacted by thunderstorms. In the Andaman Sea and the Gulf of Thailand, sea waves are expected to reach heights of approximately 1 metre, with waves reaching over 2 metres in areas experiencing thunderstorms. Mariners are advised to avoid sailing in stormy areas.
Meanwhile, Typhoon Omphul is situated southeast of Japan and is expected to pass through the eastern part of the country. This typhoon is not expected to affect the weather conditions in Thailand. However, travellers planning to visit the aforementioned areas are advised to check the weather conditions before their trip.
