On September 6, 2026, the Thai Meteorological Department issued a weather advisory warning of heavy rainfall across 39 provinces. According to the report, a monsoon trough is currently passing through the northern and upper northeastern regions of Thailand, which is expected to cause significant precipitation over the next 24 hours.
