Heavy rain and Cyclone Mocha warning for north and northeast Thailand

The meteorological department warns that heavy rain is expected in north and northeast Thailand, with Cyclone Mocha contributing to the wet weather conditions today, May 14, and tomorrow, May 15. Continuous rain and heavy downpours in some areas of the northern and upper northeastern regions have prompted the public to be cautious of flooding, flash floods, and forest runoffs. Farmers have been advised to prepare and watch out for potential damage to crops.

This is due to southerly and southeasterly winds covering the upper part of Thailand, along with a low-pressure area covering the Gulf of Tongkin.

For the Andaman Sea, southern regions, and the Gulf of Thailand, southerly and southwesterly winds dominate, resulting in thunderstorms and occasional heavy rainfall. At the upper Andaman Sea, waves could reach 2 to 3 metres in height and more than 3 metres in offshore areas. Meanwhile, the lower Andaman Sea has waves reaching 1 to 2 metres high, with taller waves in stormy areas.

For those sailing in the Andaman Sea, it is advised to be cautious and avoid stormy areas. Small boats in the upper Andaman Sea should refrain from leaving the shore until May 15. Cyclone Mocha in the upper Bay of Bengal is expected to make its way to the Myanmar coast today, affecting the northern, northeastern, and central parts of Thailand with continuous rain and heavy downpours in some areas.

Meanwhile, air quality remains good in Thailand as the density of dust particles and smog remains low due to increased rainfall and better airflow.
