Last night and today, July 10, the mountainous and midland areas of the North had moderate rain, heavy rain and thunderstorms, some places had very heavy rain. According to the meteorological agency, heavy rain in the North is tending to widen and increase.
Mr. Nguyen Van Huong, Head of Weather Forecasting Department, National Center for Hydro-Meteorological Forecasting (Department of Hydro-Meteorology, Ministry of Agriculture and Environment) has issued notable warnings regarding the impact of this rain.
Sir, during the heavy rain in the North, when is the peak rain forecast?
- The heavy rain in the North has started since the night of July 9 in the midlands and mountainous areas. It is forecasted that from now until around July 12, the northern region is likely to experience a period of moderate to heavy rain over a wide area. The rain will occur in two main stages: the first stage, from the night of July 9 to July 10 with total rainfall of 30mm - 70mm, some places over 150mm.
The second phase, from the night of July 10 to July 12, will have concentrated rainfall on July 11 and July 12, generally from 70mm - 150mm, in some places over 300mm.
In fact, in recent rains, dangerous natural disasters have appeared due to heavy rain. During this rain, what is the warning of the risk of extreme rain, sir?
- During this rain, we continue to warn of the risk of heavy rain. On July 10, the North is likely to experience extreme rain with up to 100mm of rainfall within 3 hours. From the night of July 10 to July 12, the intensity of rain can reach 150mm in 3 hours.
What is the most notable warning of the impact of this heavy rain, sir?
- In the past two months of May and June, the total rainfall in the Northern provinces, especially the mountainous and midland areas, was 20% to 60% higher than the average of many years. Therefore, this heavy rain occurred on a saturated rock and soil caused by heavy rain before, the risk of flash floods and landslides in the midland mountainous areas of the North is very high.
We consider the mountainous and midland areas of the North such as Lang Son, Cao Bang, Thai Nguyen, Lao Cai as areas at high risk of flash floods and landslides.
The Northern Delta such as Hanoi, Hung Yen, Hai Phong, Ninh Binh are areas at risk of local flooding due to heavy rain.
Sincerely thank you!
Regarding the rainfall trend in July, the total rainfall in the North and the provinces from Thanh Hoa to Quang Tri is generally 20 - 50% higher than the average of many years in the same period; the remaining areas are generally 5 - 15% lower than the average of many years in the same period.
In July, the Northern region, Thanh Hoa to Ha Tinh are likely to experience some widespread heavy rains. In the Central and Southern highlands, it is forecasted to continue to have many thunderstorms, with some days having heavy to very heavy rain, the rain will be concentrated in the late afternoon.
