The rather strong high-pressure system from China covering upper Thailand and the South China Sea is weakening while the moderate northeast monsoon prevails over the Gulf and the South. Isolated heavy to very heavy rains are forecast in the South especially in Prachuap Khiri Khan, Chumphon and Surat Thani Province. An increase in temperature with isolated rains are forecast over upper Thailand while cool with morning light fog are possible in the North and the Northeast regions. The weakening wind and waves in the lower Gulf are expected about 2 meters high and above 2 meters high in thundershowers.

People in the South should beware of heavy to very heavy rains and accumulations that may cause flash flood and overflows, especially along the waterways near foothills and lowlands. People in the upper country keep healthy due to changeable weather. Farmers should prevent for crop’s damage due to isolated rains. All ships should proceed with caution and keep off thundershowers.
