The non-stop rain in the last few days throughout Vietnam, especially in the Northern area has resulted in serious impacts on the daily life of thousands of people and the agricultural sector.
According to the National Center for Hydro-Meteorological Forecasting, on August 3rd, 2023, the North and the area from Thanh Hoa to Quang Binh, the Central Highlands and the Southeast region will have moderate rain to heavy rain, with the common rainfall from 20-50mm, at some places over 100mm (the time of rain is concentrated in the afternoon and at night). From August 4th, the heavy rain in the North, North Central, Central Highlands and Southeast regions tends to decrease gradually. Large-scale thunderstorms and local heavy rains in the Northern mountainous region are likely to last about 3-4 days. The level of natural disaster risk due to heavy rain, whirlwind, lightning, and hail is at level 1.
Regarding the reason for the prolonged heavy rain forecast in the North, the meteorological agency said that due to the appearance of a low pressure trench on the afternoon of August 2nd. This low pressure trough continues with the widespread rain taking place in the North, so the rain will last until August 8th. Thus, it can be understood that this is a new rain that follows the old rain, not a rain that lasts longer than forecast.
Serious impacts recorded
This summer-autumn rice crop, Bac Lieu province sowed more than 58,000 hectares, however, heavy rains for many days have caused more than 1,000 hectares of ripe rice to fall, and the damage rate is 30-50%. More than 31,000 hectares of late summer-autumn rice were flooded with water nearly to the neck of cotton, and this rice area is forecasted to continue to fall in the coming days when the water in the field lowers.
Heavy rains have continued for the past few days, causing many areas in Gia Nghia City (Dak Nong) to be heavily flooded. Some routes are divided locally, making it very difficult for transportation. From the night of 30 to the morning of July 31st, heavy rain continuously occurred in Dak Nong (especially in Gia Nghia city area), causing many houses and properties of people to be heavily flooded. According to the forecast of the hydrometeorological agency, heavy rain in Dak Nong will continue to occur on July 31 and the following days.
