Thailand Meteorological Department Issues Heavy Rain and Flash Flood Warning
Authorities have issued a severe weather warning for multiple regions across Thailand, effective through October 25, 2026, due to heavy rainfall and potential flash floods.
The Thai Meteorological Department (TMD) has released its sixth weather advisory (No. 265/2569), warning of heavy to very heavy rainfall across Thailand from October 19 to October 25, 2026. According to Khaosod Online, the weather pattern is driven by a monsoon trough over the central southern region, combined with a high-pressure system from China and prevailing southwesterly winds.
From October 19–20, the southern and eastern regions are expected to experience continuous heavy rain. From October 21–25, the impact is forecast to expand to the lower northeastern region, central Thailand—including Bangkok and its vicinity—the eastern region, and the upper southern region. Residents and travelers in these areas should prepare for potential flash floods, forest runoff, and landslides, particularly in low-lying areas and near mountain slopes.
Additionally, the TMD warns of strong wind gusts and rough sea conditions. In the Andaman Sea and the Gulf of Thailand, waves in areas with thunderstorms are expected to exceed three meters. Mariners are advised to exercise extreme caution. Travelers are encouraged to monitor local updates, avoid flood-prone routes, and exercise caution when navigating areas susceptible to water accumulation. As this is a developing weather event, specific localized impacts may change; residents should follow official announcements for the most current safety guidance.
