Heavy rains forecast for over 60 provinces, including Bangkok

More than 60 provinces, including Bangkok, are expected to experience increased rainfall, with isolated heavy to very heavy showers, between May 23 and 27

According to the Thai Meteorological Department (TMD)'s Weather Advisory No 6, released on Friday, the southwest monsoon prevailing over the Andaman Sea, Thailand, and the Gulf of Thailand will strengthen, while the monsoon trough will lie across upper Thailand and the upper southern region.

The TMD advises residents to be cautious of heavy to very heavy rainfall and potential accumulations that could lead to flash floods and river overflows, particularly in areas near foothills and lowlands. The public is also urged to maintain good health amid the fluctuating weather conditions.

Farmers are encouraged to safeguard their crops by enhancing drainage systems in agricultural areas to minimise damage to both crops and livestock.The strengthening winds will cause waves in the upper Andaman Sea to reach around two metres in height, with waves ranging from one to two metres in the lower Andaman Sea, and exceeding two metres during thundershowers.

All vessels operating in the Andaman Sea and the Gulf of Thailand are advised to navigate with caution and avoid thundershowers, the department warned.Affected areas are as follow:
