Authorities in Thailand have issued a nationwide weather advisory warning of thunderstorms across multiple regions, including the capital city of Bangkok. Residents in several parts of the country have been advised to remain alert as unstable weather conditions are expected to develop.
The warning was issued by the Thailand Meteorological Department, which said a moderate high-pressure system moving south from China is influencing weather patterns across upper Thailand.
As a result, easterly and south-easterly winds are pushing humid air across the country, creating favourable conditions for thunderstorms in 29 provinces over the next 24 hours.
While rainfall is expected to gradually ease in some areas, isolated storms could still occur, particularly during the afternoon and evening.
Hot Temperatures Expected Despite Thunderstorms
Weather officials said many parts of the country will continue to experience hot daytime conditions despite the possibility of rain.
The central region, which includes Bangkok and nearby provinces, is expected to see temperatures rising to between 34°C and 36°C. Residents have been advised to stay hydrated and take precautions against heat-related health issues.
Meteorologists also warned that sudden thunderstorms could develop in certain areas, bringing brief heavy rainfall, gusty winds and lightning.
Authorities have encouraged people to monitor weather updates and avoid outdoor activities when storms develop.
Storm Activity Across Northern And Northeastern Regions
In northern Thailand, thunderstorms are forecast to affect about 20 per cent of the region. Areas such as Chiang Mai, Chiang Rai and Mae Hong Son are among the provinces expected to experience rainfall.
Temperatures in the north may range between 18°C and 24°C during the early morning, rising to between 27°C and 35°C during the day.
Meanwhile, the northeastern region could see storms in roughly 10 per cent of the area. Provinces such as Nakhon Ratchasima and Loei are among the locations expected to receive rain.
Wind speeds across the region are predicted to range between 10 and 30 kilometres per hour.
Coastal Regions Warned Of Stronger Waves
Conditions along Thailand’s southern coastlines may also become unstable as moderate easterly winds move across the Gulf of Thailand and the Andaman Sea.
Waves in the lower Gulf are expected to reach between one and two metres, with heights potentially exceeding two metres during thunderstorms.
Sailors and fishermen have been advised to exercise caution and avoid travelling during stormy conditions.
Along the eastern coastline, provinces such as Chon Buri, Rayong and Trat may experience hot weather with occasional thunderstorms.
Meteorologists said coastal waves could reach around one metre under normal conditions but may grow significantly stronger during storms.
Air Quality Concerns In Bangkok And Central Thailand
Apart from weather concerns, officials also noted that dust and haze levels across much of upper Thailand remain at moderate levels.
However, the central region — including Bangkok — is experiencing poorer air circulation, which could cause air quality to rise to moderate or high levels.
Authorities are advising residents, especially those with respiratory conditions, to monitor air quality updates and limit outdoor exposure if pollution levels increase.
The weather department continues to monitor the situation and will issue further advisories if conditions worsen in the coming days.
