According to the meteorological agency, this afternoon (May 10), cold air has weakly affected the northern mountainous areas and the Northeast region. Mr. Vu Anh Tuan - Deputy Head of Weather Forecasting Department, National Center for Hydro-Meteorological Forecasting (Department of Hydro-Meteorology) has given noteworthy forecast information and warnings about the rainfall due to the impact of this cold air mass.
Sir, what is the notable impact of the upcoming cold air mass?
- Around the evening and night of May 10, the cold air will strengthen, affecting the North, North Central and some places in the Central Central region.
The notable impact is the influence of cold air compressing the low pressure trough, so around the evening and night of May 10, the Northern provinces will experience a widespread rainstorm.
The Northern region will have moderate rain, heavy rain, locally very heavy rain and thunderstorms with common sea rainfall from 30 - 70mm, locally over 100mm.
From the evening of May 10 to May 11, the area from Thanh Hoa to Quang Binh will have moderate rain, heavy rain, locally very heavy rain and thunderstorms; in the Central Central region, there will be scattered showers and thunderstorms, locally heavy rain.
After this rain, what is the forecast for rainfall in the northern region in May, sir?
- In May, total rainfall in the Northern provinces is forecast to be approximately the average of many years.
In the Northern region, from May 14 to May 16, there may also be local showers and thunderstorms. The time is mainly in the late afternoon and evening. After this period, the North may heat up and there is a possibility of rain again by the end of the month. We will monitor this form further.
What should be noted about the rain during this period, what recommendations do you have for the people?
- The North and North Central regions are in the transition period from the cold season to the hot season. Thus, the possibility of a relatively strong and chaotic change of weather is very high. Therefore, it is warned that thunderstorms may cause tornadoes, lightning, hail and strong gusts of wind.
And also during this period, the Northern and North Central provinces may experience local heavy rain.
In particular, on the night of May 10 and May 11, the three-hour rainfall may exceed 80 mm. With such rainfall, there is a risk of flooding in low-lying areas; flash floods on small rivers and streams, landslides on steep slopes, especially in mountainous provinces.
Heavy rain in a short period of time caused flooding in urban areas and industrial parks.
Sincerely thank you!
