The Thai Meteorological Department has warned that summer storms are set to hit 48 provinces across Thailand, including Bangkok, with rain forecast over 30% of the area and risks of thunderstorms, strong winds, hail and lightning.

The Thai Meteorological Department’s 24-hour forecast says the North, Central region, East, as well as Bangkok and vicinity, will continue to see summer storms in some areas, characterised by thunderstorms, gusty winds and hail, as well as possible lightning in some places.

This is because a westerly trough from Myanmar continues to cover the North, while another moderate high-pressure system, or cold air mass, from China has moved over the Northeast, the East, the eastern side of the Central region and the South China Sea.

People in upper Thailand are advised to beware of the dangers posed by summer storms by avoiding open areas, large trees, buildings and unstable billboards.

Farmers should reinforce fruit trees and prepare to prevent possible damage to crops and livestock, while also taking care of their health during the changing weather conditions.

The South should brace for heavy rain, with waves higher than 2 metres.

The South will see thunderstorms and isolated heavy rain because easterly and north-easterly winds are prevailing over the Gulf of Thailand, the South and the Andaman Sea.

Winds and waves in the lower Gulf of Thailand are moderate, with waves 1-2 metres high.

In areas with thunderstorms, waves will be higher than 2 metres.

Mariners in the Gulf of Thailand and the Andaman Sea should avoid sailing in areas with thunderstorms.

Dust during this period

Thailand’s dust and haze accumulation remains at good to moderate levels because ventilation conditions have improved.
