Southern (West Coast)

The moderate high pressure system covers upper Thailand with morning cool. People should keep healthy and beware of fire. The northeast monsoon and the easterly wind prevail across the Gulf of Thailand and the Andaman Sea with isolated thundershower in the South. The weakening wind forces the waves in the lower Gulf 1-2 meters high and in thundershowers more than 2 meters high. All ships in the lower Gulf should proceed with caution and keep off thundershowers. From 24 to 28 February, the intense high pressure system from China will extend to upper Thailand and the South China Sea with cooler condition. The temperature will decrease by 2-5 °C with strong winds. In another part, the northeast monsoon across the Gulf and the Andaman Sea will become stronger with more rain in the South. Isolated heavy rains are also possible. The wind is rather strong forcing the waves 2-4 meters high in the Gulf and more than 4 meters high in thundershowers. The waves in the Andaman Sea are likely 1-2 meters high.
