Torrential rain and thunderstorms set to impact 36 provinces, particularly affecting Bangkok significantly
Thunderstorm Warning Affects 36 Provinces in Thailand
A thunderstorm warning has been issued by the Thai Meteorological Department, affecting 36 provinces across the country. This severe weather system is expected to bring heavy rain, strong winds, and elevated sea waves to various regions, including Bangkok and its surrounding areas.
Mariners Advised to Navigate with Caution
Mariners in the Andaman Sea and the Gulf of Thailand are urged to exercise caution due to waves reaching 1 to over 2 metres high, especially in areas experiencing thunderstorms. Moderate to high waves, generally around 1 to 2 metres, can rise above 2 metres during thunderstorms. Strong southwesterly winds (15–30 km/h) can increase sea roughness, while storms and heavy rain lead to reduced visibility and hazardous navigation conditions. Specific areas such as the upper Andaman Sea and upper Gulf are more prone to 2-metre or higher waves during such weather.
To ensure safety, mariners are advised to avoid sailing or operating vessels in areas with ongoing thunderstorms and heavy storms. Navigation should be carried out with extreme caution where travel is necessary, monitoring for sudden weather changes. Preparations for strong winds and rough seas should be made, and risky maneuvers avoided. Official weather updates from the Thai Meteorological Department should be monitored for timely warnings and guidance. If operating near coastal river mouths, potential flash floods or increased river discharges should be considered.
Impacts on Residents
Residents in the affected provinces are also advised to be cautious of potential hazards from thunderstorms. South-westerly winds of 10-30 km/h are expected in various regions, and waves in storm-affected areas are expected to rise over 2 metres.
