The system is expected to bring heavy rain, flash floods and landslides across provinces in central and northern Vietnam.
The National Center for Hydro-Meteorological Forecasting (NCHMF) said at 7 p.m. Saturday the storm lay centered roughly 120 km south of the Hoang Sa (Paracels) area. Moving at nearly twice the average forward speed for storms, Bualoi has a broad impact zone and could trigger strong winds, torrential rain, river flooding, flash floods, landslides and coastal inundation.
By 7 a.m. on Sunday, the storm is forecast to be offshore from Quang Tri–Hue with winds of 112-149 kph, advancing at about 30 kph. By afternoon, it is expected to make landfall from Nghe An to northern Quang Tri with similar intensity, before tracking west-northwest into Laos and weaken to a low-pressure area.
Earlier the typhoon had been forecast to hit central Vietnam on Monday morning.

Regional agencies offered similar projections. Japan Meteorological Agency put current winds near 126 kph and forecast a peak of 144 kph along the central coast toward northern Quang Tri, while Hong Kong Obsevatory expects the storm center to cross Ha Tinh–Nghe An with winds around 155 kph.
Although the eye remains offshore, heavy rain has already hit many localities. From 9 p.m. Friday to 6 p.m. Saturday, rainfall reached 356 mm in one station of Thanh Hoa Province, 346 mm in Nghe An, 218 mm in Quang Tri, 330 mm in Hue and 235 mm in Da Nang.
Hoang Phuc Lam, NCHMF deputy director, said the current downpours are from the storm’s outer bands and will be intermittent until Saturday night, when rain becomes continuous with varying intensity. He warned of high risks of urban flooding, flash floods and landslides even before landfall.
