This year, at least 4-5 storms affect the mainland.

According to the preliminary assessment of the weather trend of this year's rainy and stormy season by the National Center for Hydro-Meteorological Forecasting, there will be about 4-5 storms directly affecting the mainland of Vietnam, and the heat wave will also appear earlier than in other years.

At the beginning of this year, storms and tropical depressions appeared early in the East Sea. Therefore, during the rainy, stormy and flood season, the weather and hydrological situation across the country will be complicated, so it is necessary to proactively guard against strong storms with complex movements, heavy rain in a short period of time causing flash floods and landslides in the areas, especially in the mountainous areas of the North, the Central Coast and the Central Highlands.

The drought and saltwater intrusion situation at river mouths in the coastal provinces of Central, South Central and Southern regions is likely to last until the end of August this year. The number of storms and tropical depressions operating in the East Sea is likely to be slightly lower than the average value of many years, at about 9-10 storms (average of many years is 10-12 storms).

Storms that directly affect the mainland of Vietnam are also at a lower level, about 4-5 storms (average of many years is 5-6 storms). However, we need to be on guard against strong storms that have complex movements and do not follow the climate or tropical depressions; storms will also have a concentrated impact in a short period of time.

On a national scale, the temperature this March and next April will be approximately the average of many years. In particular, the Northwest region will be slightly higher than the average of many years in the same period. Specifically, from May to October, the average temperature nationwide during the rainy and stormy months will generally be slightly higher than the average of many years in the same period. In particular, heat waves are likely to appear early, especially in the provinces of the Northwest, North Central and South. The number of severe heat waves in the North may be concentrated from May to July, in the Central region it may last from May to August.

Rainfall trends in the regions are as follows: The rainfall in the North this March and next April will be slightly lower than the average for the same period of many years. However, it is necessary to be on guard against strong thunderstorms accompanied by tornadoes, hail during this period. The rainy season may come later than usual, the total rainfall in the first half of the season (from May to July this year) is low; the second half of the season (from August to October) will be at a level approximately equal to the average for many years. Heavy rains in the North will be concentrated in the period from June to August next.

In the Central coastal provinces, rainfall this March and next April will be slightly lower than the average for the same period of many years. Rainfall from May to October this year will generally be low. In the provinces from Nghe An to Ninh Thuan, from May to August is the dry season, rainfall is forecast to be lower than the average for many years. Therefore, the water shortage and drought in this area will gradually improve by the end of August this year.

The Southern and Central Highlands regions this March and next April will have lower rainfall than the average of many years. The first half of the season (from May to July) will have generally low rainfall; the second half of the season (from August to October) will be at a level approximately equal to the average of many years for the same period.

It is likely that the rainy season in the Central Highlands, the South and Binh Thuan province will come later than usual (in the second half of May and early June). The lack of rain and local drought in the Central Highlands, the South and Binh Thuan province is likely to last until the end of May and will gradually improve by early June./.
