Heavy rainfall forecast across Thailand with thunderstorms in 70% of regions

The Thai Meteorological Department (TMD) has issued a weather warning for today, forecasting heavy rainfall across the northern, northeastern, central, and eastern regions, as well as Bangkok, with a likelihood of up to 70% in some areas. These conditions are due to the convergence of a monsoon trough over northern and northeastern Thailand towards a low-pressure area along the central Vietnamese coast. This is coupled with the southwest monsoon prevailing over the Andaman Sea, Thailand, and the Gulf of Thailand, resulting in heavy rainfall in certain parts of the country.

For the northern region, thunderstorms are expected in 70% of the area, with heavy rainfall in certain localities, specifically in the provinces of Mae Hong Son, Chiang Mai, Chiang Rai, Sukhothai, Tak, Kamphaeng Phet, Phitsanulok, Phichit, and Phetchabun.
