Get ready to be drenched, the Thai Meteorological Department (TMD) warned that Bangkok and 38 provinces are in for a lashing, with heavy rain, flash floods and forest runoffs on the cards. The TMD have sounded the alarm, urging residents, especially those in low-lying areas or near rivers and canals, to stay on high alert as the downpours roll in.
The warning covers large swathes of the country, with the TMD advising people to keep an eye on updates and avoid risky areas prone to sudden flooding or landslides.
The weather forecast for the next 24 hours suggests thunderstorms and heavy rainfall in certain areas of Thailand. Notably affected provinces include Chiang Rai, Phayao, Nan, Nong Khai, Bueng Kan, Udon Thani, Sakon Nakhon, Nakhon Phanom, and Trat.
This weather pattern is attributed to a low-pressure area over northern Vietnam combined with a moderately strong southwest monsoon covering the Andaman Sea, Thailand, and the Gulf of Thailand.
The TMD has issued a 15-day forecast for significant rain accumulation, prompting preparations for heavy downpours. The upper Andaman Sea is expected to experience strong winds, with waves reaching heights of 2 to 3 metres and over 3 metres during thunderstorms.
In contrast, the lower Andaman Sea will see waves around 2 metres high. Meanwhile, the upper Gulf of Thailand will have waves between 1 and 2 metres high, exceeding 2 metres in stormy areas.
Mariners in the Andaman Sea and the Gulf of Thailand are advised to exercise caution, especially avoiding navigation during storms. Small boats in the upper Andaman Sea should remain ashore during this period.
