Thailand Issues Heavy Rain and Flash Flood Warning for 34 Provinces
The Thai Meteorological Department has issued a severe weather warning for 34 provinces, citing strong monsoon conditions and potential flash floods.
On August 10, 2026, the Thai Meteorological Department (TMD) issued a weather alert for 34 provinces across Thailand, warning of heavy rainfall covering approximately 70% of these areas. According to Khaosod Online, this weather pattern is driven by a monsoon trough passing through the upper northern region and Laos, combined with a relatively strong southwest monsoon affecting the Andaman Sea and the Gulf of Thailand.
Residents and travelers in the affected regions are advised to exercise caution regarding potential flash floods and forest runoff, particularly in low-lying areas and near mountain slopes. The TMD has also reported rough sea conditions in the upper Andaman Sea and the upper Gulf of Thailand, with wave heights reaching 2 to 3 meters, and exceeding 3 meters in areas experiencing thunderstorms.
For those currently in Thailand, it is recommended to monitor local weather updates closely. Small boats in the upper Andaman Sea and the upper Gulf of Thailand have been advised to remain ashore. While the TMD has provided a 24-hour forecast, the duration of these specific weather conditions remains subject to change based on atmospheric developments. Travelers should prioritize safety and avoid navigating through areas prone to heavy rain or thunderstorm activity.
