Thailand is expected to see heavy rainfall in 33 provinces, with the southern region at a high risk of flash floods and landslides. The Thai Meteorological Department is advising people to stay vigilant starting from June 2, as 70% of the area is likely to experience torrential downpours.
According to the department’s 24-hour weather forecast, thunderstorms and heavy rainfall are predicted in specific areas of the eastern and southern provinces. Residents in these regions are urged to remain alert for potential flash floods and forest runoff, particularly in hilly areas, near water bodies, and low-lying zones. This weather event is attributed to the prevailing strong southwest monsoon, which continues to affect the Andaman Sea, southern Thailand, and the Gulf of Thailand.
Sailors in the Andaman Sea and the Gulf of Thailand are also cautioned due to rough seas. Waves are expected to reach 2 to 3 meters in height in the Andaman Sea, with even higher waves during thunderstorms. In the Gulf of Thailand, waves are predicted to be 1 to 2 meters high, increasing during storm activity. It is recommended that small boats in the Andaman Sea refrain from making trips until June 6.
In the northeastern regions, there is a 20% chance of thunderstorms with strong winds in certain parts. Provinces such as Nong Khai, Bueng Kan, Sakon Nakhon, Nakhon Phanom, Chaiyaphum, Nakhon Ratchasima, Buri Ram, Surin, Sisaket, and Ubon Ratchathani can expect temperatures ranging from 24 to 28°C during the day and 36 to 39°C at their peak, accompanied by southwest winds blowing at speeds of 10 to 20 kilometers per hour.
