Heavy rain warnings and flash flood risks in nine Thai provinces
Heavy rain warnings have been issued for nine provinces in Thailand, with risks of flash floods, forest runoff, and overflowing rivers. Coastal areas are also facing 2 metre high waves, while Bangkok experiences morning fog and cooler temperatures of 23 degrees Celsius.
A moderate northeast monsoon currently affects the Gulf of Thailand and the southern regions, combined with a low-pressure area over the Strait of Malacca expected to move towards Sumatra. This weather pattern is causing heavy rainfall in parts of the southern region.
Residents in these areas are advised to be cautious of potential hazards such as flash floods, forest runoff, and river overflows, particularly in mountainous terrains and low-lying areas.
In the lower Gulf of Thailand, moderate wind and wave conditions prevail, with waves reaching approximately 2 metres. Thunderstorm-affected areas may experience even higher waves. Mariners in these regions are advised to avoid sailing in stormy areas due to the increased risks.
The high-pressure system or cold air mass covering northern Thailand is weakening, resulting in morning fog but still cooler temperatures in the northern and northeastern regions. Mountainous and high-altitude areas will experience cold to very cold conditions, with temperatures dropping to between 10 and 16 degrees Celsius on mountaintops and between 12 and 17 degrees Celsius on high peaks.
Residents are urged to take health precautions due to changing weather conditions and to be mindful of fire hazards due to dry conditions. Additionally, caution is advised when travelling through foggy areas.
