Storm Than Gio is not strong but brings a terrible 'water bomb', equal to half a year's rain in the South.

When making landfall, the wind level of Typhoon Than Gio is not high, but the amount of rain it causes is terrible, with rainfall in some places exceeding 900mm, causing unpredictable dangers.

This afternoon, the National Center for Hydro-Meteorological Forecasting said that Typhoon Than Gio (Typhoon No. 12) is in the northern sea area of ​​Hoang Sa special zone, about 420km east-northeast of Da Nang city. The strongest wind near the center of the storm is level 9-10 (75-102km/h), gusting to level 12. The storm is moving west-southwest at a speed of 10-15km/h.

Due to the storm's influence, the western sea area of ​​the northern East Sea (including Hoang Sa special zone) has strong winds of level 7-8, the area near the storm's eye has strong winds of level 9-10, gusting to level 12. Waves are 3-5m high, the area near the storm's eye is 5-7m high, the sea is very rough.

The sea area from Quang Tri to Quang Ngai (including Con Co special zone, Cu Lao Cham island and Ly Son special zone) has strong winds of level 6. From the morning of October 22, it increased to level 7, the area near the storm center passed level 8, gusting to level 10, waves 3 - 5m high, rough seas.

Coastal areas from Quang Tri to Da Nang City have storm surges of 0.3 - 0.5m. All ships and boats operating in the above-mentioned dangerous areas are likely to be affected by storms, whirlwinds, strong winds and large waves.

Coastal areas from Quang Tri to Da Nang need to be on guard against big waves combined with high tides and rising water due to strong winds causing flooding in low-lying areas and coastal erosion.

Although storm No. 12 will have wind levels that are not too high when it makes landfall, due to the influence of the storm's circulation combined with the cold air that will intensify from tomorrow afternoon, October 22, on the mainland coastal provinces from Quang Tri to Da Nang, the wind will gradually increase to level 6, sometimes level 7, gusting to level 8-9.

From noon tomorrow, October 22 to October 27, the area from Ha Tinh to Quang Ngai is likely to have widespread heavy rain (heavy rain concentrated from the afternoon of October 22 to the end of October 23).

Total rainfall in Ha Tinh to northern Quang Tri and Quang Ngai is about 200-400mm, in some places over 500mm. In the area of ​​southern Quang Tri to Da Nang city, it is generally 500-700mm, in some places over 900mm. Warning of heavy rain (>200mm/3 hours).

Thus, the rain caused by storm No. 12 in the Central region is nearly equal to half a year's rain in some southern provinces.

Heavy rains in the Central region are likely to last until the end of October. There is a high risk of flash floods and landslides in mountainous areas, and flooding in low-lying and urban areas.

Localities need to pay attention to safely operating hydroelectric and irrigation reservoirs before, during and after the storm, and prepare response plans for flood scenarios on rivers from Quang Tri to Quang Ngai that could reach and exceed alert level 3.
