AFTER the low-pressure area is forecast to weaken on 25 December, night temperatures across the country may continue to drop and become colder, said meteorologist U Win Naing.

The low-pressure area INVEST-91B over the southwest Bay of Bengal is forecast to weaken near the Tamil Nadu coast on 25 December after moving eastward and southward on 21 and 22 December respectively, he said, quoting the ICON Model update at 2:00 am on 21 December.

The possibility of rain in Myanmar may decrease, he added.

“Due to the continuous low-pressure areas below, cold currents from the north cannot enter well, leading to less coldness in areas such as Ayeyawady and Yangon regions. With no low-pressure area, both northern and Himalayan currents can enter, making it colder,” he said.

Due to El Niño, temperatures in Myanmar rose to become the 15th hottest country in the world in early 2024. Unusual disasters include heavy rains in the upper reaches of the Ayeyawady and Chindwin rivers, which caused flooding along the banks, and another unusual flooding in eastern and southern Shan State and central Myanmar due to remnants of a typhoon in the South China Sea.

“Accordingly, we observed the La Niña phenomenon. The initial forecast showed 70 per cent likely, and now it is 59 per cent likely for the strongest La Niña event to happen in January, February, and March next year. If it is, it will be a weak La Niña, so it will not be colder, and there will not be cold waves,” he said.

Therefore, he forecasts that Myanmar’s weather in 2025 may be like normal and unusual events may decrease.
