Statistics from the National Center for Hydro-Meteorological Forecasting indicate that in the past 10 years, there has never been a year when all three regions of North, Central, and South Vietnam experienced heatwaves simultaneously during the period from April 30 to May 1.
On the evening of April 25, Mr. Nguyen Van Huong, Head of the Weather Forecasting Department at the National Center for Hydro-Meteorological Forecasting, stated that this year’s April 30 to May 1 holiday will feature particularly extreme weather. In the last decade, there has never been a year when all three regions of the North, Central, and South experienced heatwaves during this holiday period.
The most noteworthy condition in the coming days will be the heatwave. During the holiday on April 30, the Northern region and Central provinces will be affected by the hot low-pressure system from the West.
Due to the influence of this hot low-pressure system, from April 26 to around April 30, the Northern region will experience severe heat, with the highest temperatures in the Northwest ranging from 36 to 39 degrees Celsius, and some areas exceeding 40 degrees Celsius; in the Northeast and the capital Hanoi, temperatures will range from 36 to 38 degrees Celsius, with some areas exceeding 38 degrees Celsius.
The Central provinces from Thanh Hoa to Phu Yen will experience extreme heat and particularly severe heat, with temperatures ranging from 37 to 40 degrees Celsius, and some areas exceeding 40 degrees Celsius.
The Central Highlands and Southern regions will also experience widespread heat from April 26 to 30, with temperatures ranging from 35 to 37 degrees Celsius, and some areas exceeding 38 degrees Celsius.
During the April 30 to May 1 holiday, the whole country will experience intense heat. (Illustrative image).
It is forecasted that after the April 30 holiday, in the first 1-2 days of May 2024, a weak cold air mass from the Chinese mainland will move down, and in the Northern region, there is a possibility of rain showers and thunderstorms returning on May 1-2. In the Southern region, the Southwest wind will also tend to appear, causing rain and thunderstorms.
During the initial days of May 2024 in both the Northern and Southern regions, caution is advised regarding thunderstorms, tornadoes, lightning, hail, and strong winds.
Looking further ahead, from now until June (with a focus on May), there will be a transition in weather from the cold season to the hot season, and from the dry season to the rainy season in the Northern region. Thus, severe thunderstorms accompanied by tornadoes, lightning, hail, and strong winds are expected to occur frequently during this time. In mountainous areas, the influence of the terrain may create strong convective cloud formations, resulting in thunderstorms, tornadoes, lightning, hail, and strong winds.
