According to the National Center for Hydro-Meteorological Forecasting, the 4/30-5/1 holiday this year lasts 5 days, coinciding with the transitional season in the North and Central regions, so the weather across the country will have many notable fluctuations, especially a widespread heat wave right before the holiday.

It is forecasted that from April 17, mountainous areas from Nghe An to Quang Ngai provinces will begin to experience widespread heat waves, with the highest temperatures ranging from 35-37 degrees Celsius, with some places above 37 degrees Celsius.

Mr. Mai Van Khiem, Director of the National Center for Hydro-Meteorological Forecasting, said that this heat wave in the North and Central regions is likely to last until April 23, while the South is likely to continue to be hot for many more days.

From around April 23-28, due to the influence of weak cold air, the North is likely to experience showers and thunderstorms, with temperatures dropping slightly. In the Central region, the heat will narrow down, only occurring locally.

During the holiday, from April 30 to May 4, it is forecasted that there will be little rain in the North and temperatures will increase again; from May 3 to 4, there may be heat waves; in the Central region, heat waves will continue, but not as severe as in mid-April; the South will continue to experience widespread heat waves with temperatures ranging from 34 to 37 degrees Celsius.

The Hydrometeorological Agency warns that during the transitional season, extreme weather events such as thunderstorms, tornadoes, lightning, hail, and strong gusts of wind may occur, especially in the evening. At the same time, widespread heat in the coming days may have adverse effects on people's health, increase the risk of explosions, forest fires, and affect production and daily life. People need to regularly monitor weather forecasts to proactively prevent and ensure safety for production, daily life, and tourism activities during the holidays.

To ensure that weather information is provided promptly, accurately, and fully, serving people's tourism and travel activities, as well as organizing events during the April 30 - May 1 holiday, the Department of Hydrometeorology has directed the National Center for Hydrometeorological Forecasting to coordinate with relevant units to develop a detailed plan for weather forecasting and warning during the period from April 15 to May 5.

According to the plan, from April 20, the Center will increase the frequency of issuing forecast bulletins, closely monitor and provide early warnings of dangerous weather phenomena such as: heavy rain, thunderstorms, tornadoes, strong winds at sea, hail, etc. to help people, local authorities and related units proactively prevent and minimize damage.

In particular, forecasting work will focus on major event areas across the country, ensuring information is continuously updated, close to reality, effectively serving the organization and ensuring safety for outdoor activities during the holidays.
