Thai Meteorological Department Issues Heavy Rain Warning for 37 Provinces

On September 3, 2026, the Thai Meteorological Department (TMD) issued a weather alert for 37 provinces across the Northern, Northeastern, Eastern, and Southern regions. According to Khaosod Online, the forecast indicates that 60% of these areas will experience heavy rainfall. This weather pattern is driven by a monsoon trough passing through the upper North and Laos, connecting to Tropical Storm 'Sodel' currently located in the upper South China Sea.

For residents and travelers, the TMD warns of potential flash floods and forest runoff, particularly in low-lying areas and regions near hillsides. Authorities advise avoiding travel through routes prone to recurring flooding. Additionally, maritime conditions in the Andaman Sea and the Gulf of Thailand are expected to be moderate, with waves reaching approximately 2 meters in the upper Andaman Sea, and higher in areas affected by thunderstorms. Mariners are urged to exercise caution and avoid navigating through storm-affected zones.

While the storm is projected to make landfall in southern China by the night of September 3, the immediate impact on Thailand remains a concern due to accumulated rainfall. Travelers should monitor local weather updates closely, as the situation regarding specific flood-prone areas remains subject to change based on real-time precipitation levels.
