Storm Krovanh formed from a tropical depression in the East Vietnam Sea on Sunday and is now heading toward the maritime area off southern provinces, according to the National Center for Hydro-meteorological Forecasting.
The storm, the 14th to hit Vietnam in 2020, was located at 270 kilometers northeast of the Huyen Tran (Alexandra) Bank within Vietnam's Truong Sa (Spratly) archipelago as of 7:00 am on Monday, packing wind speed of 60-75km per hour.
It is expected to travel southwest in the next 24 hours and weaken into a tropical depression.
By 7:00 am on Tuesday, the low-pressure system will have been located at 100 kilometers northwest of Huyen Tran Bank.
Average wind speed will decrease to between 40km and 60km per hour.
By Wednesday morning, the tropical depression will have been at 80 kilometers southeast of Con Dao Islands off the southern province of Ba Ria-Vung Tau, with winds at 40-50km an hour.
It will travel west in the next 48 to 72 hours and continue to weaken.
Due to the storm circulation, rough seas, high waves, and rain will occur in the central and southern sections of the East Vietnam Sea in the coming days.
As the storm will weaken at sea, it will not have big impacts on the weather in the mainland, Mai Van Khiem, director of the National Center for Hydro-meteorological Forecasting, said at a meeting with the national steering committee for natural disaster prevention on Monday morning.
From Tuesday, rainfall of 30-70 millimeters will dampen southern localities, Khiem added.
About 2,000 fishing boats operating in the affected areas have been advised to take shelter during this period.
