Thundershowers expected across Thailand, with heavy rain in the South

Upper Thailand will see isolated thundershowers and gusty winds, while the South faces thundershowers and isolated heavy rain, the Thai Meteorological Department (TMD) said.

A heat low-pressure cell is currently covering upper Thailand, bringing hot to very hot conditions during the day. Meanwhile, southerly and south-westerly winds are prevailing over the region.

“People in the upper country are advised to take care of their health due to the hot to very hot weather, and to remain alert for potentially severe conditions, including gusty winds,” the department stated.Westerly and north-westerly winds are prevailing over the Andaman Sea and the South, where a low-pressure cell is covering the Strait of Malacca. This is expected to result in thundershowers and isolated heavy rainfall across the southern region.

“People in the South should be cautious of thundershowers,” the TMD warned.



The department also forecast that wind and wave conditions in the Gulf of Thailand and the Andaman Sea are likely to reach about one metre in height, and exceed two metres during thundershowers.

All vessels in the Gulf and the Andaman Sea are advised to avoid navigating through areas experiencing thundershowers.
