A high-pressure system, or cold air mass, from China has spread over upper Thailand and the South China Sea, bringing easterly winds across the Gulf of Thailand, the country and the Andaman Sea, according to TMD.
TMD advised people in upper Thailand to take precautions against heavy rain, thundershowers and gusty winds by avoiding open areas, sheltering under large trees, and standing near unsecured structures or billboards.
Mariners in the Andaman Sea and Gulf of Thailand should navigate cautiously and avoid areas with thundershowers, where waves may exceed two metres, TMD advised.
