Severe Weather Alert Issued for Thailand
Monsoon Brings Heavy Rainfall and Flood Risks
Thailand’s Meteorological Department has issued an urgent warning for May 25–27, forecasting heavy to very heavy rainfall across the country. The intensified southwest monsoon, combined with a powerful monsoon trough moving through upper Thailand and the southern regions, is expected to trigger flash floods, runoff, and landslides, particularly in low-lying areas and near foothills or waterways. Residents are urged to stay vigilant and prepare for severe weather conditions.
Flooding Incidents Reported in Phuket
Overflow from Red Mountain Golf Club Reservoir
In Phuket’s Kathu district, heavy rainfall caused muddy water from the Red Mountain Golf Club’s reservoir to spill onto nearby roads, creating hazardous conditions. This incident highlights the immediate impact of the monsoon’s intensity. Authorities are advising residents to avoid flood-prone zones and exercise caution while traveling, especially in areas prone to thunderstorms or landslides near hills and riverbanks.
Rough Seas Forecast for Coastal Regions
Andaman Sea and Gulf of Thailand on High Alert
Maritime conditions are worsening due to the monsoon’s effects. In the Upper Andaman Sea, waves are expected to reach up to 2 meters, with higher surges in stormy areas. The Lower Andaman Sea will see waves between 1–2 meters, while the Gulf of Thailand anticipates waves around 1 meter, increasing during thunderstorms. Small boats in the Upper Andaman Sea are strongly advised to remain docked until May 27 to ensure safety.

Post-Storm Outlook and Ongoing Risks
Flash Flood Threat Lingers Beyond May 27
While weather conditions are expected to improve slightly from May 28 to 31, the risk of flash floods remains, especially in the northern and northeastern regions where heavy rainfall may persist.
