On the morning of August 27, many roads in Hanoi were still flooded. Some areas were still deeply flooded such as Thang Long Avenue, Hoai Duc urban area, Xa La intersection (Pham Tu), National Highway 32 through Tan Tay Do...

An Khanh urban area is still submerged in water on the morning of August 27, vehicles cannot pass through.

Vehicles cannot pass through these locations. The Dam Quang Trung - Co Linh intersection is also flooded, causing traffic congestion.

To Lich River (Hanoi) is "full of water"

The reason many places are still flooded is because the current system of regulating lakes in Hanoi is "full of water". At the same time, drainage rivers such as To Lich River, Nhue River... are at high levels due to rainwater flowing from Hanoi's inner city and from upstream.

Water on rivers drains slowly because the water level of Day River and Tich River in the West and Southwest of Hanoi is rising rapidly.

When the water level in the Nhue River or the Day River is higher than the inner city, the sluices must be closed to prevent water from overflowing, so the inner city can only be drained by forced pumping at large stations such as Yen So, Dong Bong, and Co Nhue.

Hoang Cau Lake and other rainwater reservoirs in Hanoi are full of water and draining slowly due to flooding in suburban rivers.

Currently, Hanoi Drainage Company has mobilized all its capabilities to drain water in Hanoi's inner city. Yen So pumping station (in the South of Hanoi) is operating at full capacity of ^90m3 /second. At the same time, more than 2,000 drainage workers are on duty, opening the discharge gates of a series of regulating lakes such as Bay Mau, Thien Quang, Truc Bach, Giang Vo...

A residential bridge in the West of Hanoi was flooded on the night of August 26.

According to SGGP reporters, since yesterday afternoon and evening, floodwaters on the Day River and the Tich River in Hanoi have begun to rise rapidly, causing flooding on some bridges across the Day River in the An Khanh and Hung Dao communes of Hanoi. The rising water level of the Day River has reduced the drainage capacity of the Nhue and To Lich Rivers.

Day River water flooded Dai Thanh bridge (Hanoi) from the evening of August 26.

At the same time, the risk of flooding is also high along the rivers. The Department of Dyke Management and Natural Disaster Prevention has sent a dispatch to the Hanoi Department of Agriculture and Environment requesting urgent review and protection of dykes at vulnerable locations, increased patrolling and guarding, and timely reporting of incidents for coordination in handling.

The Northern Hydrometeorological Station said that on August 27, rain continued in many areas of the North. Hanoi still had moderate rain, heavy rain with thunderstorms, locally very heavy rain. From this afternoon, the rain gradually decreased. The meteorological agency warned that the risk of tornadoes, lightning, strong gusts of wind in thunderstorms, the risk of flooding, flash floods, and landslides remained high, requiring continued monitoring and response.
