Mr. Khiem warned that heavy rain in the Central region is likely to last until the end of October 2025. There is a high risk of flash floods and landslides in mountainous areas, flooding in low-lying areas and urban areas. Localities need to pay attention to safe operation of hydroelectric reservoirs and irrigation before, during and after the storm; prepare response plans for flood scenarios on rivers from Quang Tri to Quang Ngai that may reach alert level 3 and exceed alert level 3. Forecast level of natural disaster risk due to floods and inundation is level 3.
Beware of the risk of thunderstorms, whirlwinds and strong gusts of wind in the area affected by the storm's circulation, both before and during the storm's landfall.
At sea, the sea area west of the northern East Sea (including Hoang Sa special zone) has strong winds of level 7-8, near the center of the storm level 9, gusts of level 11, waves 4-6 m high, very rough seas. The sea area from Quang Tri to Quang Ngai (including Con Co special area, Cu Lao Cham island and Ly Son special area) will have strong winds of level 6-7, the area near the storm's eye will have strong winds of level 8-9, gusts of level 11, waves 3-5 m high, very rough seas. The coastal areas of the provinces from Quang Tri to Da Nang city will have storm surge of 0.4-0.8 m high.
The coast and river mouths from Quang Tri to Da Nang city need to be on guard against big waves combined with high tides and storm surges causing flooding in low-lying areas, waves overflowing coastal roads, and the risk of coastal erosion. All ships and aquaculture areas in the danger zone are likely to be affected by thunderstorms, whirlwinds, strong winds, large waves and high tides.
