Meanwhile, discharges from three reservoirs into downstream of the Vu Gia River reach 1,613m3/s. In which, discharges from reservoir of the Song Tranh 2 hydropower plant are only 5.7 m3/s.

At 4:00 am on Sunday, water levels on the Vu Gia River at the part of the Ai Nghia Hydrological Station reached 6.75m, 0.25m above alarm level 1 as a result of heavy rains and water discharged by reservoirs.

The Mid-Central Region Centre for Hydro-meteorological Forecasting has predicted heavy to very heavy rainfall in the parts from Quang Binh to Quang Ngai, including Da Nang, from the early morning of October 17 into October 17  due to the combined influence of cold air and the intertropical convergence zone. By the coast they will see strong winds at level 3 to 4 and the gusts as high as level at 5 to 6, and farther inland you could find northeast winds at level 3.

The coastal areas from Quang Binh to Quang Ngai, including Da Nang, will see gradually increasing wind at level 6-7, and the gusts reaching level 8, and experience rough seas.
