Heavy Rainfall and Rough Seas Alert Issued for Thailand
The Thai Meteorological Department has issued a weather warning for heavy rain and high waves across several regions due to a strong southwest monsoon.
Weather Alert Overview
On August 28, 2026, the Thai Meteorological Department (TMD) issued an advisory regarding a strong southwest monsoon currently affecting the Andaman Sea, Thailand, and the Gulf of Thailand. This weather pattern is being influenced by a monsoon trough extending across neighboring countries, including Myanmar, Laos, and Vietnam.
Impacted Areas and Risks
Forecasters expect isolated heavy to very heavy rainfall in the Eastern region, with additional heavy rain possible in the North, upper Northeast, western Central region, and the southwest coast of the South. Residents and travelers in these areas are advised to remain cautious of potential flash floods, water overflows, and landslides, particularly near foothills and low-lying waterways.
Maritime Conditions
Marine conditions are also affected, with the upper Andaman Sea experiencing strong winds. Waves are currently forecast to reach heights of 2 to 3 meters, potentially exceeding 3 meters during thundershowers.
What Remains to be Confirmed
While the TMD has provided these regional forecasts, the specific duration of this weather system and the exact intensity of rainfall in localized areas remain subject to change. Travelers are encouraged to monitor official TMD updates regularly for real-time adjustments to these warnings as the monsoon trough evolves.
