Heavy rainfall warning issued for 46 provinces including Bangkok

The Meteorological Department has issued a severe weather warning, forecasting heavy rainfall in 46 provinces, including Bangkok, with 70% of the area expected to be affected. Residents are advised to take precautions against potential flash floods and forest runoff.

Moderate southwesterly monsoon winds are covering the Andaman Sea, Thailand, and the Gulf of Thailand, coupled with a low-pressure area over the upper northern region. This weather pattern will bring heavy to very heavy rain in certain areas, particularly in the eastern region.

Residents in these areas are urged to be cautious of the accumulated rainfall, which could lead to sudden flooding and forest runoff, especially in low-lying areas and near mountainous terrain. Caution is also advised when travelling through areas experiencing thunderstorms.

In the Andaman Sea and the Gulf of Thailand, moderate sea conditions are expected. The upper Andaman Sea will see waves of one to two metres high, while the lower Andaman Sea and the Gulf of Thailand will have waves of about 1 metre. In areas with thunderstorms, waves could exceed 2 metres. Mariners in these regions should navigate with caution and avoid sailing in stormy conditions.

“Please be aware of the potential for heavy rainfall and sudden flooding. Those in affected areas, particularly near mountains and waterways, should exercise caution.”

Tropical Storm Maliksi made landfall near Yangjiang, Guangdong Province, China today at 1am. The storm is moving north-northeast at approximately 15 kilometres per hour and is expected to weaken into a tropical depression and then into a low-pressure area.
