According to the National Center for Hydro-Meteorological Forecasting, this morning (October 20), Storm No. 5 strengthened by 1 level, reaching nearly level 9, with gusts up to level 11.
However, by 7 AM this morning, the storm returned to its initial level, with strong winds at level 8 (62-74 km/h), gusting to level 10 and currently located over the northeastern sea area of the Gulf of Tonkin.
The storm is currently moving northeast at a speed of about 10 km/h, but due to the influence of cold air, in the next 24 hours, the storm will make a sudden turn of 180 degrees towards the southwest at a speed of about 5-10 km/h and gradually weaken into a tropical depression.
By 7 AM on October 21, the depression will be located over the eastern Gulf of Tonkin. Wind speeds will decrease to level 7, with gusts up to level 9.
In the next 48 hours, the tropical depression will move southwest at a speed of about 10 km/h and weaken into an area of low pressure over the southern Gulf of Tonkin.
Due to the impact of Storm No. 5, today the Gulf of Tonkin region (including Co To and Bach Long Vi islands) will experience strong winds at levels 6-7, with levels 8 near the center of the storm, gusting up to level 10, causing rough seas.
The seas in the Gulf of Tonkin (including Co To and Bach Long Vi islands) will have wave heights of 2.0-4.0m. All ships, anchorage areas, aquaculture zones, and coastal dikes in this area are affected by strong winds and large waves.
On land, the northeastern region of the Northern Delta will have rain, with moderate to heavy showers in some places.
Additionally, on October 20, a portion of cold air will affect the northeastern region, then spread to the North Central region and some areas in the Northwest. Northeasterly winds inland will be strong at levels 2-3, while near the coast, wind speeds will reach levels 4-5, gusting to levels 6-7, with some coastal areas in Quang Ninh-Hai Phong experiencing strong winds at level 6, gusting to levels 7-8.
From the night of October 20, the Northern Delta and North Central regions will turn cold, with some areas in the northern mountains experiencing chilly temperatures. During this cold air surge, the lowest temperatures in the Northern Delta and North Central regions will generally range from 19-22 degrees Celsius, while the mountainous areas in the north will see temperatures commonly between 16-19 degrees Celsius, with some high mountain areas dropping below 14 degrees Celsius.
