On the afternoon of April 25, Mr. Nguyen Van Huong, Head of Weather Forecasting Department, National Center for Hydrometeorological Forecasting, said that this year’s April 30 – May 1 holiday lasts 5 days and the weather is similar. for special.

“Our statistics over the past 10 years have shown that there has never been a year when all three regions had hot weather during this period,” Mr. Huong assessed.

According to Mr. Huong, from about April 26-30, the North will experience a widespread heat wave with the highest temperature in the Northeast, including the capital Hanoi at 37-38 degrees, in some places above 38 degrees. degree; In the Northwest, the intensity is stronger, from 36-39 degrees, with some places over 40 degrees.

In particular, the Central provinces, from Thanh Hoa to Phu Yen, will experience intense and especially intense heat with high temperatures of 37-40 degrees, in some places over 40 degrees. Particularly in the western mountainous region from Thanh Hoa to Quang Ngai, the temperature in some places exceeds 41 degrees.

In the Central Highlands and Southern regions, in the period from April 26-30, there was also widespread heat with high temperatures of 35-37 degrees, in some places above 38 degrees.

In addition, Mr. Huong said that it is forecast that after April 30, in the first 1-2 days of May, there is a possibility of an interaction similar to the situation on April 24. That is high heat and weak cold air moving down from the North, causing thunderstorms in the North, with the focus being on the Northern midland mountains, around the night of May 30 and May 1. The impact of these weather patterns does not exclude the possibility of thunderstorms, lightning storms and strong winds.

With the above hot weather situation, Mr. Huong explained that the reason is that the weather is being affected by the El Nino phenomenon, causing the temperature throughout the country to be higher than the average for many years. In addition, this period is being affected by the hot low pressure area in the West, causing a widespread heat wave during the holiday period.

Forecasting further, Mr. Huong commented that from now until June (with a focus on May) is the period of weather change from cold season to hot season, dry season to rainy season in the North. Therefore, strong thunderstorms accompanied by tornadoes, lightning, and hail are most likely to appear during the year, especially in mountainous areas due to the impact of terrain, which can create strongly developed convective clouds. The time of thunderstorms, tornadoes and lightning, especially hail and strong winds in the North, Thanh Hoa, Nghe An and Ha Tinh areas often appear in the afternoon, evening and night.

The meteorological agency noted that to limit the impact, people need to regularly monitor hydrometeorological warning information through television channels, newspapers, and the meteorological agency’s online warning portal. hydrological statue.
