Heavy rain and flash floods expected across Bangkok and regions

Heavy rain is expected in Bangkok and several other regions warns the Thai Meteorological Department (TMD). Residents are advised to prepare for potential flash floods, especially in hilly and low-lying areas, due to intense rainfall and accumulated precipitation.
