From the next 72 to 120 hours, the storm will move mainly in the West Southwest direction, about 5km per hour, and its intensity will continue to weaken.

Due to the influence of storm Koinu, the weather in the northeastern sea of ​​the North East Sea has strong winds of level 7-10, from the afternoon of October 5, the area near the storm's eye will have winds of level 11-12, gusting to level 15; the sea is rough; the waves are 2-4m high; from tonight, they will be 4-6m high, from tomorrow afternoon (October 5), the area near the storm's eye will have waves of 6-8m high.

On land, this evening and tonight, the area from Quang Nam to Phu Yen, the Central Highlands and the South will have scattered showers and thunderstorms, locally with moderate to heavy rain with rainfall of 10-30mm, some places over 50mm (rain concentrated in the late afternoon and evening). During thunderstorms, there is a possibility of tornadoes, lightning, and strong gusts of wind.

Localized heavy rains are likely to cause flooding in low-lying areas, and the risk of flash floods and landslides in mountainous areas.

Previously, the meteorological agency assessed that in October, storms and tropical depressions are likely to appear in the East Sea about 1-2 times and may affect the mainland of our country.

Further, the agency said that from now until the end of 2023, there will likely be about 2-4 storms/tropical depressions in the East Sea, of which about 1-2 will directly affect our mainland. Be on guard against storms with complex developments in both trajectory and intensity.

The North is likely to have its first cold air mass soon.

The North is experiencing sunny days, sometimes quite hot. But the first cold air mass is likely to appear in the next week.
