Thailand Meteorological Department Issues Heavy Rain Warning for October 18–25
Authorities have issued a severe weather alert for widespread heavy rainfall, flash floods, and strong winds across multiple regions of Thailand.
The Thai Meteorological Department (TMD) has released its first official warning (No. 260/2569) regarding heavy to very heavy rainfall expected across the country from October 18 to 25, 2026. According to Khaosod Online, the weather pattern is driven by a monsoon trough shifting across the southern and eastern regions, combined with a high-pressure system moving in from China.
From October 18–20, 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, Bangkok and its vicinity, and the upper southern region. These areas may face heavy downpours accompanied by gusty winds.
Residents and travelers are advised to exercise caution regarding potential flash floods, forest runoff, and landslides, particularly in low-lying areas and near mountain slopes. Authorities recommend avoiding travel through routes prone to recurring flooding. Additionally, sea conditions in the Andaman Sea and the Gulf of Thailand are expected to be rough, with wave heights exceeding three meters in areas affected by thunderstorms.
While the TMD has provided a clear timeline, the specific intensity of rainfall in localized areas remains subject to change. Residents and visitors should monitor official updates from the Meteorological Department for real-time developments and localized warnings.
