The maximum wind speed near the center of the tropical depression is currently at level 6, with gusts reaching level 8.

The tropical depression is moving primarily in a northwest direction at a speed of about 5 km/h. It is forecasted that within the next 24 hours, it will continue to move northwest at the same speed and enter the Gulf of Tonkin. By 7 PM on August 21, the center of the tropical depression is expected to be at around 20.0 degrees North latitude and 108.4 degrees East longitude, approximately 200 km southeast of Hai Phong.

At this time, the tropical depression is likely to strengthen into a storm, with wind speeds reaching level 8 and gusts up to level 10. The Gulf of Tonkin has been warned to be at risk level 3 for natural disasters.

In the following 24 hours, the storm is expected to continue moving northwest at a speed of 3-5 km/h. By 7 PM on August 22, the storm's center is predicted to be at around 20.3 degrees North latitude and 107.6 degrees East longitude, approximately 110 km southeast of Hai Phong.
