Recently, the National Center for Hydro-Meteorological Forecasting released the seasonal hydro-meteorological forecast bulletin nationwide (from August 2024 to January 2025).
The reporter had a discussion with Dr. Hoang Phuc Lam - Deputy Director of the National Center for Hydro-Meteorological Forecasting - about the most notable weather features during this period.
Sir, from mid-July until now, these two regions have experienced many heavy rain days; sunshine only appeared intermittently. In the coming time, is there a possibility that the hot weather pattern will return, sir?
- Since June, the Northern, Central, Central Highlands, and Southern regions have recorded several heat waves. In the Northern region, hot weather is forecasted to occur until August 2024. In the North Central and Central Central regions, hot weather will occur until September with decreasing intensity compared to July and August.
From August to October, the average temperature is generally 0.5 - 1 degree Celsius higher than the multi-year average for the same period. After that, from November 2024 to January 2025, the temperature nationwide will be approximately the same as the multi-year average for the same period.
So, when is the forecasted onset of cold air that will gradually lower the temperature, sir?
- Cold air is forecasted to start from September or October and increase in intensity and frequency in December 2024 and January 2025. Severe cold and damaging cold are likely to appear at the end of December 2024 and January 2025.
During the cold air season, as every year, it is necessary to be cautious of the possibility of frost and ice in the high mountainous areas of the Northern region.
During the forecast period, the rainy season's developments are also of interest to the public. Do you have any notes on this year's rainfall trend?
- Regarding the rainfall trend, the total rainfall from now until the end of the year in the Northern and Central regions is generally higher than the multi-year average for the same period.
The rainy season in the Central region is likely to appear similar to the multi-year average, which is around the end of August and the first half of September.
Heavy rains are forecasted to be concentrated towards the end of the year, especially in the Central region, increasing the risk of prolonged flooding, widespread floods, flash floods, and landslides in this area.
The rainy season in the Central Highlands and Southern regions is likely to end approximately or later than the multi-year average.
Thank you very much!
