TMD director-general Wanchai Sakudomchai said Thailand officially enters the rainy season this week due to the influence of southwesterly winds. In this rainy season, heavy downpours could hit the Andaman coastal provinces, such as Ranong, Phangnga and Krabi, as well as the eastern provinces of Chanthaburi and Trat, according to Mr Wanchai. A southeasterly wind has brought humidity from the Gulf of Thailand to the Northeast, East, Central Plains and South, with thundershowers and isolated heavy rain across those areas expected. As the country enters the rainy season, some provinces already experienced summer storms earlier this month. Storms were also seen in the capital over the weekend as heavy rainfall drenched some parts of the city.
