The Thai Meteorological Department has issued a new weather warning for Thursday, alerting people across the country about heavy rain, flash floods, and rough seas. The department explained that the monsoon trough is stretching from Myanmar and northern Thailand into a low-pressure area over northern Laos and northern Vietnam. At the same time, a moderate southwest monsoon is covering the Andaman Sea, Thailand, and the Gulf of Thailand, bringing unstable weather to many regions.

Risk of Flooding and Overflow

According to the forecast, heavy rain is likely in many parts of Thailand. People living near rivers, canals, foothills, and low-lying areas are being urged to stay watchful, as the continuous downpour could cause flash floods, sudden water overflows, and mudslides. Authorities have asked local residents to keep an eye on weather updates and prepare for possible emergency situations.

High Waves in the Sea

The department also warned about strong winds and high waves. In the upper part of the Andaman Sea, waves could reach around 2 metres, while in the lower Andaman Sea and the upper Gulf of Thailand, waves may rise between 1 and 2 metres. If thunderstorms occur, waves could grow even higher, crossing 2 metres. All fishing boats and small vessels are advised to be very careful and avoid sailing during thundershowers, while larger ships are asked to move with caution.

Ongoing Storm Threats

The weather warning follows the weakening of Tropical Depression Kajiki earlier this week, which turned into a low-pressure system but still brought heavy rain to northern provinces. Even though Kajiki has faded, the department has cautioned that more rain is expected and a new storm may form soon, increasing the risk of flooding in several regions.

Authorities are closely monitoring the situation and have asked people in all affected areas to stay alert, avoid risky areas near rivers or stormy seas, and follow safety instructions from local officials.
