Mr. Hoang Phuc Lam – Deputy Director of the National Center for Hydrometeorological Forecasting warns of rains in the Central region with high intensity and total rains, lasting many days, the risk of tube flooding, flash floods, landslides. mountains, widespread flooding in river basins and large urban areas.
The central region is considered a high risk area affected by the strong low pressure zone that turns into a tropical depression in the East Sea.
Mr. Hoang Phuc Lam – Deputy Director of the National Center for Hydrometeorological Forecasts has given detailed forecasts on the situation of prolonged heavy rains in central Vietnam.
Sir, could you tell us about the evolution of large-scale heavy rains in central Vietnam as of 6.10 today?
– As of June 6, due to the influence of the northeast monsoon combined with the activity of a low vortex capable of turning into a tropical depression in the Middle East Sea. At 7:00 am on October 6, the center of the low-pressure area was about 60 kilometers northwest of Song Tu Tay Island.
In the next 24 hours, the low pressure area is forecast to move mainly to the west, every hour about 10 km and is likely to develop into a tropical depression.
At 7:00 a.m. As of October 7, the location of the low pressure tropical center is about 12.1 degrees north latitude; 111.0 degrees East Kinh, about 180 km off the coast from Binh Dinh to Khanh Hoa provinces to the east. The strongest wind in the area near the center of the strong tropical depression is at level 6-7.
Due to the influence of the tropical convergent strip that passes through the center of Vietnam (in the tropical convergence, there are areas of low pressure with the ability to strengthen in tropical depression) and combined with the activity of cold air, so from 6.10 At 11.10 in the central provinces it is likely to rain a lot with a popular total rainfall of 300-500mm / hour, particularly Ha Tinh to Quang Ngai provinces have very heavy rains with popular rains of 500-700mm / lot.
North Central Highlands provinces have moderate rains, heavy rains, some places with very heavy rains with popular rains of 200-350mm / hour; The southern and southern central highland provinces have moderate rainfall, some places with heavy to very heavy rains with popular rains of 150-250 mm / hour. two.
Lord, when will the peak of this rain be?
– The combination of precipitation factors for the Central region will be strongest on the days of October 7 to 9, when the tropical low / low pressure zone will approach the central and south central coast.
At that time, the central central region, provinces / cities from Quang Binh to Quang Ngai will be affected by a combination of northeast monsoons, the northern edge of the tropical low / low pressure region and the extent of the terrain. Northwest – Southeast so it is very likely that this is the moment with the highest intensity and total precipitation of 24 hours of this rain.
So how long will the forecast heavy rains last, and what dangerous weather patterns may occur?
– The National Center for Hydrometeorological Prediction that after October 11, the heavy rains in the central provinces have had complicated and lasting developments. The reason is that the tropical convergence band still passes through the Central region, in this tropical convergence, another tropical cyclone may appear on October 12 and 13, then move towards the Central. Furthermore, the northeast wind is still active, so although the intensity of the rain may decrease compared to the peak (7-9.10), there will still be heavy rains on a large scale and there is no point signal. fully detained in the central provinces until October 15.
High intensity rainfall and total rainfall, lasting many days, risk of tube flooding, flash flooding, landslides in mountainous areas, widespread flooding in river basins and large urban areas. Rain, flooding, and flooding can affect small, critical irrigation reservoirs that can cause problems. Local authorities should review plans to respond to heavy rains and floods in advance in order to be more active in prevention.
Thank you sincerely!
