Vessels operating within the storm-affected areas, especially near the Hoang Sa Archipelago and the coastal waters from Quang Binh to Quang Ngai, are at risk of thunderstorms, strong winds, and high waves.

The authorities have issued alerts for high risks of erosion and damage to dykes and coastal structures from Quang Tri to Quang Nam due to high waves and storm surges.

On land, strong winds will begin to impact the coastal areas from Quang Binh to Quang Ngai from October 27, with winds ranging from levels 6-7 and up to levels 8-9 near the storm's core, with gusts reaching level 11.
