The Thai Meteorological Department (TMD) issued a weather warning, predicting heavy rains across 19 provinces with rainfall affecting 80% of the area. The Gulf of Thailand is expected to experience waves over 3 metres high, and temperatures are set to drop by 3 degrees Celsius with strong winds.
The strong northeast monsoon sweeping through the Gulf of Thailand and the southern regions, coupled with a low-pressure system moving across the southern Gulf and Malaysia, is driving these adverse weather conditions. Residents in the affected areas are advised to be cautious of heavy to very heavy rainfall and the potential for flash floods and rapid water flows, particularly in mountainous terrains, near waterways, and low-lying areas.
“Residents should remain vigilant as the weather patterns could lead to dangerous flash floods,” warned officials.
In the Gulf of Thailand, the sea conditions are particularly rough, with waves reaching heights of 2 to 3 metres and exceeding 3 metres in areas with thunderstorms. The upper Andaman Sea is also expecting waves about 2 metres high, increasing beyond 2 metres in thunderstorm zones.
Officials have urged seafarers in the Gulf and the Andaman Sea to proceed with caution and avoid sailing in stormy areas. Small boats in the Gulf have been advised to remain ashore, while those in the southern region (eastern coast) should be wary of strong waves hitting the shore.
A high-pressure system or cold air mass from China is covering the upper parts of Thailand and the South China Sea, causing cooler weather in the upper regions of Thailand. Temperatures are expected to decrease by 1 to 3 degrees Celsius, with strong winds contributing to the chilly conditions.
Heavy rains
Mountain tops and peaks are experiencing cold weather, prompting advice for residents to take care of their health amidst these changing conditions. The likelihood of accumulating dust and haze in the upper regions of Thailand is decreasing due to the stronger winds and rainfall.
“The drop in temperature and strong winds are contributing to lower dust accumulation,” said the TMD.
