"The weather at sea and in coastal areas during the storm is extremely dangerous and unsafe for any vehicles or structures operating in the danger zone such as: cruise ships, passenger ships, transport ships, cages, rafts, aquaculture areas, dykes, embankments, and coastal routes. Vehicles are highly likely to capsize or be destroyed; flooded due to strong winds, big waves, and rising sea levels," Mr. Khiem emphasized.
Storm No. 5 is very dangerous, it combines three high-risk factors: strong winds, high waves and very heavy rain. There is a high risk of flooding of dikes, coastal roads, river mouths, especially in the coastal areas of Nghe An and Thanh Hoa in the afternoon and evening of August 25; flash floods, landslides in mountainous areas, and severe flooding in low-lying areas are very high.
"People must absolutely not be subjective, comply with the government's evacuation orders, and limit going out when the storm hits. Localities must closely monitor developments and proactively deploy response measures to minimize damage," Mr. Mai Van Khiem advised./.
