The Thai Meteorological Department (TMD) today issued a warning for heavy rainfall across seven provinces in Thailand. Residents are advised to be cautious due to the risk of accumulated rainfall leading to flash floods and forest runoff. The northern regions of Thailand are experiencing a rise in temperature, although the mountain peaks remain extremely cold.
The TMD’s 24-hour weather forecast indicates that the high-pressure system or cold air mass covering upper Thailand and the South China Sea is starting to weaken. This change will cause temperatures in the northern regions to rise by 1 to 2 degrees Celsius.
Despite this increase, mornings remain chilly, and the mountain peaks continue to experience cold to very cold weather. People in these areas are advised to take care of their health due to the changing weather conditions.
The northeast monsoon, which has been quite strong over the Gulf of Thailand and the southern region, is also showing signs of weakening. As a result, there will be a decrease in rainfall in the south, although heavy rain is still expected in some areas of the southern region.
Residents in these areas should remain vigilant as heavy rain may lead to flash floods and forest runoff, particularly in hilly regions near waterways and low-lying areas.
In the lower Gulf of Thailand, strong winds persist, with sea waves reaching heights of 2 to 3 metres. In areas experiencing thunderstorms, the waves can exceed 3 metres. Mariners in both the Gulf of Thailand and the Andaman Sea are advised to navigate with caution and avoid sailing in areas where thunderstorms occur. Small boats in the lower Gulf of Thailand should refrain from leaving the shore.
