Storm Lionrock in the East Vietnam Sea has downgraded into a tropical depression and is expected to land in Vietnam’s Hai Phong - Thanh Hoa region on Sunday, while another storm is on the way to the waters, the national weather agency reported.
Tropical Storm Lionrock, the seventh storm in the East Vietnam Sea so far this year, has weakened into a tropical low pressure system on Sunday morning, the National Center for Hydro-meteorological Forecasting said.
At 10:00 am on Sunday, the depression was centered on the waters south of Quang Ninh, around 100km off Hai Phong, 150 km off south-northern Nam Dinh Province and 260km off north-central Thanh Hoa Province.
The storm packed winds of 40 to 60km per hour and squalls of up to 88km per hour, with a wind radius of 100km.
Over the next 12 hours, the storm will travel west-southwestward at 15 to 20km per hour and land in the region between northern Hai Phong City and north-central Thanh Hoa Province, with winds decreasing to 40-50km per hour.
In the next 12 to 24 hours, the depression will move in the same direction towards Laos and further weaken into a low-pressure system.
The storm eyewall, in combination with a strengthened cold front, will cause extremely rough seas in the Gulf of Tonkin, including the waters of Bach Long Vi Island, along with winds of up to 61km per hour and waves reaching two to four meters in height.
During Sunday, the coastal area from northern Quang Ninh Province to north-central Nghe An Province will have winds of 49 km per hour and squalls of up to 74km per hour.
During Sunday and next Monday, torrential rains of 150 to 250 millimeters will slash the northeastern region, while less severe rains, of 50 to 150 millimeters, will dampen the northwestern part.
Over three days from Sunday, heavy rains of up to over 150 millimeters will cover the north-central region from Nghe An to Quang Binh.
Flash floods and landslides may occur in mountainous areas while inundation is likely to hit low-lying areas.
On Saturday, many northeastern localities, including Hai Phong, Quang Ninh, Thai Binh, Nghe An, Thanh Hoa and Ha Tinh issued urgent dispatches to request concerned agencies to promptly take measures to cope with Lionrock.
Thanh Hoa Province authorities have banned all operations at sea from 5:00 pm on Saturday for safety reasons.
Meanwhile, another storm, Kompasu, has been active in the eastern waters of Luzon Island of the Philippines from Sunday morning.
At 10:am on Sunday, the storm was seen to move northwest at 25km per hour, packing winds of 75 to 90km per hours and squalls of up to 117km per hour.
Over the next 24 hours, the storm is expected to move in the same direction and get stronger.
At 10:00 am Monday, Kompasu will have been spotted 210km east-northeast off Luzon Island, with winds of up to 100km per hour and wind gusts of over 118km per hour.
In the next 24 to 48 hours, the storm will travel west at 15km per hours, continue getting stronger and enter the East Vietnam Sea, the center forecast.
