Heavy rain and landslides have also disrupted transport. Eleven landslide sites have blocked national and provincial roads, including four on National Highway 15C and three on National Highway 217. Another 30 locations have been inundated, causing traffic congestion.

The Hanoi-Ho Chi Minh City railway was submerged by about 1 meter between Bim Son and Do Len, forcing passengers to be transported by road through the flooded section.

The National Steering Committee for Civil Defense has asked ministries, sectors and localities to closely monitor developments and take proactive measures against heavy rain, floods, flash floods and landslides, particularly in Hanoi, Ninh Binh, Thanh Hoa and Phu Tho.

Affected localities have been instructed to urgently address the aftermath, monitor river levels, enhance warnings about rapidly rising floodwaters and deep inundation, and evacuate residents from areas at risk of flooding, flash floods and landslides.

Authorities have also been asked to maintain 24-hour duty to ensure timely information and coordination in disaster response.

The meteorological agency urged local authorities to review vulnerable locations and potential flow obstructions and take timely preventive measures.
