New weather news from the Southern Hydrometeorological Station said that in the coming days, the weather in the South will be affected by two consecutive cold air waves. These conditions interact with the equatorial low pressure trough and the circulation of storm No. 15, causing complex weather forecasts in the area, the possibility of thunderstorms, strong winds at sea and fluctuations in the weather on land.
According to weather forecasts, around November 26-27 and December 2-3, cold air from the North will continue to be added. The Northeast wind maintains an average intensity over the southern seas. By November 28-29, the wind direction may change when the circulation of storm No. 15 and the low pressure trough have a stronger impact.
At the same time, the equatorial low pressure trough with an axis of 6-9 degrees North latitude will gradually strengthen and connect with storm No. 15 moving west. At the upper level, the subtropical high pressure with an axis through the Central region will gradually move to the west, increasing atmospheric disturbances, thereby clearly affecting the forecast of rain in many areas.
Under the impact of the above conditions, the weather in the South (including Ho Chi Minh City) will maintain a sunny state during the day, but in the evening and at night, there will be scattered showers and thunderstorms, with moderate rain in some places. During thunderstorms, there is a possibility of tornadoes, lightning, and strong gusts of wind.
The area also began to turn cold at night and early morning from late November to early December when the cold air intensified.
At sea, storm No. 15 Koto reached level 12 intensity (118-133 km/h), gusts of level 15, and the storm moved in a West-Northwest direction at a speed of 10-15 km/h.
It is forecasted that by 7:00 a.m. on November 28, the storm will move in a West-Southwest direction at a speed of 5-10 km/h, maintaining an intensity of level 12, gusting to level 15; located at about 12.5 degrees North latitude - 113.0 degrees East longitude, in the western sea area of the Central East Sea.
At 7:00 a.m. on November 29, storm No. 15 changed direction to the West Northwest and then the Northwest at about 5 km/h, weakening to level 11, gusting to level 14 and located at 13.0 degrees Kinh Dong - 112.3 degrees North latitude.
At 7:00 a.m. on November 30, the storm continued to move slowly in the Northwest direction at a speed of 3-5 km/h, decreasing to level 10, gusting to level2; center at about 13.9 degrees North latitude - 112.0 degrees East longitude, in the northwest sea area of the Central East Sea.
In the next 72-120 hours, the storm will tend to move slowly in the North-Northwest direction, then turn west and continue to weaken.
At sea, especially in the Central East Sea area (including the sea area north of Truong Sa), strong winds of level 7-9; near the storm center, strong winds of level 10-12, gusts of level 15. Waves 4-6 m high, especially near the center of the storm, reached 7-9 m, causing fierce sea roughness and threatening the safety of ships operating in the danger zone.
