Thai Meteorological Department Issues Warning for Heavy Rain and Rough Seas
The Thai Meteorological Department has released its seventh announcement warning of severe weather conditions, including heavy rainfall and high waves across the Andaman Sea and the Gulf of Thailand.
On August 7, 2026, the Thai Meteorological Department (TMD) issued its seventh official announcement regarding volatile weather conditions across the country. According to Sukanyanee Yavinyachan, Director-General of the TMD, residents and travelers should prepare for heavy to very heavy rainfall affecting various regions of Thailand.
In addition to the precipitation, the department has issued a warning concerning maritime conditions. The upper Andaman Sea and the upper Gulf of Thailand are expected to experience rough seas, with wave heights projected to reach between 2 and 4 meters.
For residents and tourists, these conditions may lead to localized flooding and significant disruptions to maritime travel. Those planning trips to coastal areas or islands should monitor local weather updates closely, as sea conditions of this magnitude can impact ferry schedules and small boat operations.
While the announcement provides a clear warning of the current meteorological outlook, specific details regarding the duration of these conditions and the exact geographic areas most at risk of extreme flooding remain subject to further updates from the TMD. Travelers are advised to follow official guidance from local authorities and exercise caution when near the coast or in areas prone to heavy runoff.
