TMD warns of hot weather and thunderstorms across Thailand

Today, the Thai Meteorological Department (TMD) is warning that summer storms will occur across Thailand, characterised by thunderstorms, strong winds, and occasional hail. This warning is valid for the next 24 hours and includes both hot weather and torrential rain.

People living in affected areas are advised to take precautions against the dangers posed by the summer storms. They are advised to avoid being in open spaces, standing under large trees, near weak structures or billboards, wearing metal objects, and using mobile phones during thunderstorms. Farmers should take preventive measures and be aware of potential risks to agricultural produce and livestock.

Two dominant weather systems currently influence Thailand’s weather: high air pressure or cold air mass and the southern and south-easterly monsoonal winds. These conditions bring increased humidity from the Gulf of Thailand and the South China Sea, causing strong winds and higher temperatures in the upper parts of the country.

For the southern part of Thailand, the eastern and south-easterly winds are dominating the climate over the Gulf of Thailand, causing intermittent thunderstorms in certain locations. People living in affected areas should be aware of the potential dangers posed by thunderstorms.

Regarding the maritime conditions, the Andaman Sea and the Gulf of Thailand are expected to have 1 metre high waves. However, in areas with thunderstorms, waves may rise to 2 metres. Mariners are advised to navigate cautiously and avoid sailing in stormy waters.

In terms of air quality, particle accumulations in some parts of Thailand are relatively low to moderate due to ongoing rainfall, and good air circulation. The exception is the northern and northeastern regions, where particulate matter accumulations remain relatively high.
