A tropical low-pressure system that is moving west-northwest in the East Vietnam Sea will make landfall between Khanh Hoa and Binh Thuan Provinces on Wednesday morning, the national weather agency forecast.
The depression was located around 280km from Khanh Hoa Province and 258km from Ninh Thuan Province at 9:00 am on Tuesday, with winds of up to 60km per hour and squalls reaching 88km per hour, the National Center for Hydro-meteorological Forecasting said on Tuesday morning.
Over the next 24 hours, it will move west-northwest at a speed of 10km per hour toward the south-central region and be downgraded to a low-pressure system.
It will be located in the inland area between Khanh Hoa and the northern part of Binh Thuan at around 4:00 am on Wednesday, with winds blowing less than 40km per hour.
Affected by the system, the northern and middle parts of the East Vietnam Sea will have rough seas, with waves rising up to four meters as well as winds of up to 61km per hour and gusts topping 88km per hour.
The waters off Binh Dinh and Ninh Thuan Provinces will also experience sea turbulence and the same strong winds.
The northern part of the East Vietnam Sea, including the waters off Vietnam's Hoang Sa (Paracel) archipelago, and the waters off Quang Tri and Quang Ngai will have northeast winds of 49km per hour.
The coastal area from Binh Dinh to Ninh Thuan will have winds of 49km per hour and gusts of 74km per hour from Tuesday afternoon.
Showers and thunderstorms, possibly together with whirlwinds, will cover the waters of Hoang Sa and Truong Sa (Spratly) archipelagoes and the sea area off the coast from Quang Tri to Ca Mau Provinces.
During Tuesday and Wednesday, heavy rains will hit many regions from Thua Thien-Hue through the Central Highlands and to the southeastern area, with rainfall of 100 to over 350 millimeters.
Due to the cold front combined with west wind turbulence, heavy rains and downpours will strike the northern and middle parts of the central region from Wednesday to Saturday.
During the last quarter of this year, the East Vietnam Sea will see five to seven storms or tropical depressions, of which two to four will directly affect the mainland of Vietnam, the center previously forecast.
