The Thai Meteorological Department has forecast continued heavy rainfall in many areas of northern Thailand over the next 24 hours, with some areas experiencing very heavy rain. Flash floods and forest runoffs are possible, especially in mountainous and low-lying areas. Meanwhile, Bangkok and its surrounding regions will face thunderstorms across 60% of the area.
The department warns that the upper northern regions, along with upper Laos, will be affected by a monsoon trough and low-pressure system over northern Vietnam. Combined with strong southeasterly and southwesterly winds, these conditions will continue to bring heavy rainfall to the upper Northeast of Thailand. Additionally, the southwestern monsoon still affects the Andaman Sea, Thailand, and the Gulf of Thailand, contributing to rain and waves in coastal areas.
In the Andaman Sea and the Gulf of Thailand, waves are expected to reach around 1 meter, with higher waves in areas experiencing thunderstorms. Sailors are advised to avoid navigating during stormy conditions.
