Mr. Nguyen Van Hung - Vice Chairman of the People's Committee of Cua Lo Ward, said that the entire ward has 615 households that need to be evacuated because their houses are in disrepair and at risk of losing their roofs when the storm makes landfall.

Of these, 53 households were taken to concentrated shelters such as schools and cultural houses. The remaining households were temporarily housed in solid houses in the area to ensure safety before the storm.

The evacuation is carried out on the principle of prioritizing the elderly, children and households in difficult circumstances.

Faced with that situation, local authorities have assigned forces to be on duty 24/7, ready to deploy additional evacuation plans if a bad situation occurs.

Restaurants, hotels, and houses along the coast have also proactively reinforced their doors and used sandbags in front of their basements to prevent seawater from flooding in and damaging property.

Colonel Dinh Viet Dung - Director of Nghe An Provincial Police, directed the entire force to deploy a storm prevention plan according to the motto "4 on-site, 3 ready" and the action slogan "When people need, when people are in trouble, there is the police."
