Thailand braces for heavy rainfall and strong winds tomorrow

The Thai Meteorological Department (TMD) forecasts heavy to very heavy rainfall for tomorrow, affecting 41 provinces, with Bangkok expected to experience severe conditions with 80% of the area impacted by strong winds.

Thailand is bracing for a significant weather event as TMD warns of thunderstorms and strong winds nationwide. Heavy rains are anticipated in the central region, including Bangkok and its vicinity, the eastern region, and the south.

Some areas in the lower northeastern region will also see heavy rainfall. Residents in these regions are urged to be cautious of the severe weather conditions, which could lead to flash floods and overflowing streams, particularly in foothill areas near watercourses and low-lying areas.

It is advised to avoid staying in open spaces, under large trees, and near unstable structures or billboards. Additionally, people should take care of their health due to the changing weather conditions.

TMD has issued the fifth warning for this weather disturbance, noting that 80% of Bangkok and the eastern region will experience heavy rain today. This adverse weather is attributed to the monsoon trough passing over the upper southern region, combined with a low-pressure area covering the upper southern region. At the same time, a high-pressure area or cold air mass from China is extending over upper Laos, upper Vietnam, and the upper South China Sea.

This high-pressure area is expected to spread over the upper northeastern region today, bringing easterly and southeasterly winds that will carry moisture from the South China Sea and the Gulf of Thailand over the upper part of the country. Moderate wind waves are expected in the Andaman Sea and the Gulf of Thailand, with waves reaching 1 to 2 metres in height and over 2  metres in areas with thunderstorms. Mariners in these areas should proceed with caution and avoid sailing in areas prone to thunderstorms.
