The National Center for Hydro-Meteorological Forecasting said that at 4 p.m., the storm's center was about 370 km east-southeast of Guangdong (China), moving west at a speed of 10 km/h.

By 4 p.m. tomorrow, the storm's center will be about 140 km from Guangdong, down to level 10. The storm will then head west at a speed of 5-10 km/h and continue to weaken into a tropical depression on the afternoon of October 8 in the northern East Sea.

The Japan Meteorological Agency said the storm was now at 126 km/h and had weakened to a tropical depression by October 8. Hong Kong's Meteorological Agency gave a similar assessment.

Due to the influence of the storm, the northern East Sea has strong winds of level 7-10, then increasing to level 11-12, waves 2-4 m high, especially in the northeast area waves 4-6 m, near the storm center waves 6-8 m high.

Koinu is the fourth storm to enter the East Sea this year. Compared to the same period many years ago, after entering the East Sea, the storm tended to move north, not west, passing the Philippines and affecting Vietnam. Before Koinu, storm Sao La in late August and early September also followed a similar path.

The meteorological agency predicts that in October there will be 1-2 storms and tropical depressions affecting mainland Vietnam.
