Although it is only May - not yet the peak of flood season - the North has continuously recorded widespread heavy rains. According to information from the meteorological agency, the North is likely to face a new round of rain. The reporter had a quick exchange with Mr. Vu Tuan Anh - Forecaster of the National Center for Hydro-Meteorological Forecasting on the upcoming rainfall.
Sir, please tell us the time for the North to shift to rain and how to forecast the rainfall in this period?
- The North is about to face a new round of rain. From the evening of May 28 to May 29, the Northern region will have moderate rain, heavy rain and thunderstorms, locally very heavy rain with common rainfall from 30 - 90mm, locally over 180mm.
The cause of this rain is due to weak cold air compressing the low pressure trough combined with an additional wind convergence area above 1,500 meters.
From early morning on May 29, the North Central region will have moderate rain, heavy rain and thunderstorms, locally very heavy rain with common rainfall of 30 - 50mm, locally over 100mm. The rain in this area will be concentrated from the morning to the night of May 29.
Can you warn about any dangerous natural disasters that may appear in the upcoming rain?
- Recently, the North and North Central regions have experienced consecutive heavy and extreme rain. Many places have saturated, causing the risk of flash floods on small rivers and streams and landslides to increase.
Mountainous localities are prone to landslides and flash floods, especially in steep terrain areas where people live near mountain slopes or along streams.
This rain may also experience localized rain with high intensity (over 100mm in 3 hours), which increases the risk of flash floods and landslides.
In the plains, it is also necessary to pay attention to the risk of localized flooding on some roads and streets.
Sir, what is the further forecast for the rainfall trend in the coming time across the country?
- Currently, the Northern, Central Highlands and Southern regions have entered the rainy season. Therefore, the frequency of rains will be higher. In the Southern region, the southwest monsoon is more active, so there is also a possibility of rain in the coming days.
Sincerely thank you!
Forecast of rainfall from now until June 20
The National Center for Hydro-Meteorological Forecasting predicts that the total rainfall in the next month in the mountainous areas of the North, Central Highlands and the South is likely to be 10 - 25% higher than the average of many years.
The Central Central and South Central regions have total rainfall generally 5 - 20% lower than the average of many years. Other regions are approximately the same as the average of many years in the same period.
During the forecast period, the Northern region is likely to experience some moderate rain, heavy rain and thunderstorms. The southwest monsoon in the South continues to cause showers and thunderstorms in the Central Highlands and the South.
There is a possibility of dangerous weather phenomena such as thunderstorms, tornadoes, lightning, hail and strong gusts of wind across the country. In particular, it is necessary to be on guard against heavy rains that can cause floods, inundation in low-lying areas and landslides in mountainous areas.
