Affected by the "Front Meiyu" phenomenon, the North has floods and rains.

On June 27, heavy rain continued to occur in the Northwest and Viet Bac regions of our country due to bad weather. According to the National Center for Hydro-Meteorological Forecasting and meteorological experts, the focus of the flood is from the evening of June 28 to July 3 (rain is forecast to be over 500mm in some places). The cause is a low pressure trough operating in southern China has moved south, combined with high-altitude wind convergence (3,000-5,000m) and a low vortex in Northwest Vietnam, which has caused and will cause widespread heavy rain in the North.

Weather experts confirmed that this is the “Front Meiyu” phenomenon - originating from the meeting of cold air masses from the North and hot, humid air masses from the South, extending from the Tibetan Plateau through Southern China to Northern Vietnam, often appearing in the rainy season (peaking in June and July). Under the impact of the “Front Meiyu” phenomenon and the low pressure trough, Southern China is currently also experiencing prolonged heavy rain, causing serious flooding.

* Due to heavy rain in the upper Viet Bac region, the Ministry of Agriculture and Environment has ordered the opening of a bottom spillway gate of Tuyen Quang Hydropower Reservoir at 2:00 p.m. on June 27 to reduce the pressure on the reservoir and create capacity to receive early-season floods. The Ministry of Agriculture and Environment requested localities such as Tuyen Quang, Phu Tho, Vinh Phuc and Hanoi to ensure the safety of people and organizations and businesses operating on and along the river in the downstream, especially cage fish farms, water transport vehicles, ferry terminals, construction works, sand and gravel mining, etc. In the face of unusual natural disasters in 2025, the Minister of Industry and Trade has just issued Directive 11 requiring the safety of the hydropower system and the national power grid during the 2025 storm season.
