The average rainfall in the next 3 days will range from 70-150 mm, some places will exceed 300 mm. In Tuyen Quang and Lang Son provinces, heavy rain combined with mountainous terrain increases the risk of flash floods and landslides.

Faced with complex weather developments, on the afternoon of July 9, the Ministry of Agriculture and Environment requested northern localities to closely monitor forecasts and natural disaster warnings, and promptly inform local authorities and people to proactively prevent them.

At the same time, deploy shock troops to inspect and review residential areas along rivers and low-lying areas, prepare evacuation plans when necessary; strictly control culverts, deep flooding points, and areas at risk of landslides to ensure safety for people and vehicles.

Localities are also required to inspect key works, industrial parks, urban areas, mines, and mineral exploitation areas; proactively drain water, protect production, and prepare rescue forces.

Notably, to ensure the safety of the reservoir and downstream areas, the Ministry of Agriculture and Environment directed the Hoa Binh Hydropower Company to open a bottom spillway at 4:00 p.m. on July 9. The provinces and cities of Hanoi, Phu Tho, Bac Ninh, Hai Phong, Hung Yen and Ninh Binh need to widely announce so that aquaculture facilities, water transport units, riverside works, etc. can proactively take measures to protect people and property.
