A low pressure zone is building up over southern parts of the East Sea, set to aggravate the already turbulent waters of the East Sea coastline.
According to the National Hydro Meteorological Forecasting Center, at 1am on Friday, the zone was centered at 4-6 degrees north latitude and 110-112 degrees east longitude. It is forecast to remain stationary or move gradually west southwestwards within the next 24 hours.
The low pressure zone is also generating northeasterly winds of level six moving at about 39 kilometers an hour from the central and southern coasts of Vietnam.
Mid and northern parts of the East Sea are also being affected by the zone, facing the onslaught of bitter northeasterly winds.
