Rain check! Bangkok braces for a drenching deluge

webfact · October 9, 2024

The Thai Meteorological Department (TMD) issued a stark warning: heavy rain and cooler temperatures are on the horizon for tomorrow. A staggering 33 provinces will be affected by the weather with Bangkok expected to see a soggy 60% of its area drenched. Get ready for potential flooding and flash floods as the storm rolls in.

In their latest forecast, the TMD reveals that a weakening high-pressure system is currently hovering over northern Thailand. While it may be losing strength, the upper northern and northeastern regions will still feel the chill in the morning. Meanwhile, an easterly wind is sweeping in moisture from the South China Sea and the Gulf of Thailand, priming the lower northeastern, central, and eastern regions—including Bangkok—for a drenching.

This situation will lead to increased rainfall in these areas, with some places experiencing heavy rainfall, particularly in the lower central region, including Bangkok and surrounding provinces, and the eastern region. Residents in the upper part of Thailand are advised to take care of their health due to rapidly changing weather conditions.

TMD also issued a warning for seven provinces from October 13 to October 24 to be on the lookout for high sea levels. The monsoon will affect 70% of the eastern and southern regions, with warnings of flash floods and forest runoffs.

The monsoon trough passing through the central part of the southern region will cause heavy rainfall in some areas. Residents in these regions should be cautious of heavy rain and accumulated rainfall, which may lead to sudden flooding and forest runoff, especially in foothill areas near waterways and low-lying areas.

Additionally, the sea waves in the Andaman Sea and the Gulf of Thailand are expected to be weak, with waves less than 1 metre high, and over 1 to 2 metres high in thunderstorm areas. Mariners are advised to avoid sailing in areas with thunderstorms.
