TMD issues weather warning for 39 provinces, rain in Bangkok

The Meteorological Department of Thailand (TMD) issued a weather warning for 39 provinces, particularly in the northern and northeastern regions, predicting heavy rainfall in some areas. Bangkok is expected to experience rain in 30% of its area.

The TMD forecasts the weather for the next 24 hours, noting that a monsoon trough is passing through the upper part of the northern region and upper Laos, extending to a low-pressure cell over northern Vietnam and the Gulf of Tonkin.

Additionally, a moderate southwest monsoon is covering the upper Andaman Sea and the upper part of Thailand. This combination is causing heavy rainfall in the northern and upper northeastern regions, with some parts of the southern region experiencing thunderstorms.

Residents in these areas are advised to be cautious of the dangers posed by heavy rainfall.

The northern region is set to experience thunderstorms in 70% of the area, with heavy rain expected in certain provinces, including Mae Hong Son, Chiang Mai, Chiang Rai, Lampang, Phayao, Nan, Uttaradit, Tak, Phitsanulok, and Phetchabun. Temperatures will range from a low of 24 to 26 degrees Celsius to a high of 32 to 34°C. Southwesterly winds range between 10 to 20 kilometres per hour.

In the northeastern region, thunderstorms are predicted in 40% of the area, with heavy rain expected in provinces such as Loei, Nong Khai, Bueng Kan, Udon Thani, Sakon Nakhon, Nakhon Phanom, and Mukdahan.
