Extreme weather events are increasing due to the change of seasons; Be careful of tornadoes, lightning and hailstorms.

Specifically, from the afternoon of May 7 to the morning of May 8, the northern area and the provinces of Thanh Hoa and Nghe An skilled scattered rain, average rain and thunderstorms with rainfall between 20 and 40 mm, and in some localized areas, heavy to very heavy rain exceeding 100 mm.

The space between Ha Tinh and Hue City will expertise scattered showers and thunderstorms with rainfall between 10 and 30 mm, and regionally heavy rainfall exceeding 70 mm.

During the afternoon and night of May 7, the southwestern area of Vietnam skilled scattered showers and thunderstorms with rainfall of between 10 and 20 mm, and in some localized areas, heavy rain exceeding 50 mm.

Additionally, from the night time of May 8 to 11, the northwest area will expertise scattered showers and thunderstorms, with some areas experiencing heavy rain.

In the northeastern area, throughout the night time of May 8 and the day of the ninth, scattered showers and thunderstorms are anticipated in some areas, particularly in the plains, the place scattered rains and showers will probably be recorded, with thunderstorms in some areas. From May 10 to 11, scattered showers and thunderstorms are anticipated, with heavy rain in some areas.

In the central area, scattered showers and thunderstorms are anticipated in the afternoon and night, particularly in Thanh Hoa and Nghe An provinces, from the night time of May 8 and all through the day on May 9.

The southern area will expertise scattered showers and thunderstorms in some areas, particularly between May 10 and 12.

According to Nguyen Van Huong, head of the Weather Forecast Department of the National Center for Hydrometeorological Forecasting, the aforementioned phenomenon is probably going to proceed in the coming days, as it’s a pretty typical weather sample throughout the transition interval between seasons (May), particularly in the northern area, the place the environment concurrently has many favorable components for the growth of robust convection.

Furthermore, in the northern area, due to the affect of the southern edge of the low-pressure trough, compressed by the northern continental high-pressure mass, along with the convergence of the wind up to 5000 m, chilly air continues to compress and push the low-pressure trough, whose axis is roughly between 24 and 27 levels north latitude, in the direction of the south. In the afternoon, due to the enhance in temperature, the mass of heat, humid air rises strongly, forming storm clouds that develop vertically in a short time. In this extremely unstable setting, the rising air present could be very robust, holding the ice lots in the storm clouds for longer and inflicting them to develop earlier than falling. If these ice particles soften utterly earlier than reaching the floor, they’ll kind regular rain; but when they don’t soften utterly in time, they’ll kind hail.

“While this is a dangerous phenomenon, it is not entirely unexpected as it has been warned about periodically in the bulletins of the National Center for Meteorological and Hydrological Forecasting at https://www.thoitietvietnam.gov.vn,” mentioned Mr. Nguyen Van Huong.

In this case, Mr. Nguyen Van Huong defined that hailstorms are small-scale phenomena that normally accompany intense thunderstorms throughout transition seasons. Hailstorms typically current fairly distinctive indicators that folks can simply acknowledge, comparable to the look of dense storm clouds, a sudden change from heat, humid air to chilly, robust gusts of wind, and heavy rain accompanied by thunder and lightning.

It is critical for individuals to be very attentive to weather alerts. During transitional seasons, when the sky is noticed to darken and intense storm clouds are forming, indicating the danger of thunderstorms, tornadoes and hail, it is suggested to restrict out of doors journeys, search protected shelter till the storm passes earlier than persevering with journey, and keep away from standing underneath massive timber, utility poles, billboards or momentary buildings.

When hailstorms happen, individuals ought to keep indoors, shut all doorways and home windows, and keep away from contact with glass to decrease the danger of harm from breaking.

During robust gusts of wind, it’s mandatory to reinforce roofs, safe objects that may be blown by the wind, and keep away from areas in danger of collapse. Additionally, it’s a good suggestion to flip off electrical home equipment throughout thunderstorms and restrict the use of cell phones outside to scale back the danger of being struck by lightning.

Regarding the growth of the chilly entrance, the National Center for Meteorological and Hydrological Forecasting predicts that, on the night time of May 7, the chilly entrance will first have an effect on the Northeast area, then the Central-North area and some areas of the Northwest area. On land, the winds will change route in the direction of the Northeast with pressure 2-3, and at pressure 3-4 in coastal areas.

In the Northeast area and Thanh Hoa province, the weather will develop into colder from the night time of May 7. Minimum temperatures throughout this chilly interval in the Northeast area and Thanh Hoa province will typically vary between 21 and 24 levels Celsius, though some northern mountainous areas will expertise temperatures under 21 levels Celsius.

In the Hanoi space, the weather turned colder beginning on the night time of May 7. The minimal temperature throughout this chilly interval was typically 22 to 24 levels Celsius.

On the excessive seas, from the early hours of May 8, in the northern Gulf of Tonkin, the winds will change to robust northeasterly winds of pressure 4-5, with gusts up to pressure 6, waves 1-2 meters excessive and tough seas. From the afternoon and night of May 8, the northeastern maritime space of ​​the Northeast Sea will expertise robust northeasterly winds of pressure 6, with gusts of up to pressure 7-8, waves 2-3 meters excessive and tough seas.
