TMD predicts Thunderstorms across the country with heavy rainfall in Bangkok

The Thailand Meteorological Department (TMD) issued a warning for today’s weather, predicting thunderstorms across 35 provinces, with Bangkok expected to experience heavy rainfall covering 60% of its area.

The southern region is anticipated to be hit hardest, with sudden flash floods posing a danger due to heavy rainfalls.

This weather pattern is due to a high-pressure system or cool air mass from China expanding to cover Vietnam and the South China Sea. It is expected to cover northeastern Thailand today. Meanwhile, an easterly wind is blowing across the eastern, lower central, and southern regions, coupled with a low-pressure trough covering Malaysia.

Such conditions trigger thunderstorms in the lower northeastern, eastern, lower central, and southern regions. Heavy rainfall is also expected in the south. The public in the southern region is urged to be cautious of dangers from heavy rainfall and be vigilant while travelling through areas with thunderstorms.

For the Gulf of Thailand and the Andaman Sea, sea waves are below 1 metre high. In areas with thunderstorms, waves can be more than 2 metres high. Boat operators are advised to navigate cautiously and avoid areas with thunderstorms.

Between today and November 14, the southern region will experience increased rainfall and heavy rain in some areas due to the strengthening easterly wind that covers the lower south coupled with a low-pressure trough covering the Malaysian coast. People in the southern region are advised to be cautious of dangers from heavy rainfall and accumulated rain that could lead to sudden flash floods and forest runoff, especially in areas near mountain slopes, waterways, and lowlands.

Today’s weather forecast for Thailand from 6am today until 6am tomorrow predicts fog in the northern region in the morning, with slight thunderstorms in some areas. The lowest temperature is 21 to 25 degrees Celsius and the highest is 32 to 35 degrees Celsius, with an easterly wind speed of 5 to 15 kilometres per hour.
