On the morning of October 22, although storm No. 12 had not yet made landfall, many coastal low-lying areas of Da Nang city such as Hoi An had begun to be partially flooded due to heavy rain and high tides.
Many neighborhoods in the old urban area have been flooded since last night - October 21, especially Bach Dang Street. This is the area at the end of the downstream of the Vu Gia and Thu Bon river systems, so it is often flooded during heavy rains in the upstream, especially when combined with high tides.

According to the Center for Hydro-Meteorological Forecasting, at 7:00 a.m. on October 22, the center of storm No. 12 was at about 17.1 degrees North latitude; 110.7 degrees East longitude, in the northwest sea of Hoang Sa special zone, about 280 km East Northeast of Da Nang. The strongest wind near the storm center is level 10 (89-102 km/h), gusting to level 12, moving in the West Southwest direction at a speed of 10 km/h.
It is forecasted that in the next 24 to 36 hours, the storm will move in the West Southwest direction, gradually weakening into a tropical depression when entering the area from Hue to Quang Ngai, then continue to weaken when entering the mainland of Southern Laos.
Due to the influence of the storm's circulation combined with the strengthening of cold air, from the afternoon of October 22, coastal areas of Da Nang such as Hai Chau, Son Tra, Ngu Hanh Son, Hoa Khanh, Hoi An, Dien Ban... will have strong winds of level 6, sometimes level 7, gusting to level 8-9.
The meteorological agency warns that storm surge will be from 0.4-0.8m, combined with high tides causing flooding in low-lying areas, coastal roads and low-lying residential areas. Heavy rain lasted from October 22 to 27, total rainfall was generally 500700mm, some places over 900mm.
Localities need to prepare evacuation plans, proactively drain water and respond to the risk of flash floods and landslides, especially in mountainous areas and urban areas along rivers. The risk level of natural disasters due to floods and inundation is determined at level 23.
