China Forecasts Heavy Rain and Strong Winds Across Southern and Eastern Regions

What changed

China’s Central Meteorological Observatory forecasts heavy rain across parts of Guizhou, Yunnan, Hunan, Guangxi and Guangdong from October 3 to 5, with some areas receiving 100–130 millimetres between October 3 and 4. Cold air is also bringing northern winds and falling temperatures across central and eastern China, while the Bohai, Bohai Strait and northern Yellow Sea could see gusts reaching force 9 from October 4 to 5.

The observatory continued its blue wind warning on October 3. Rain in southern China is expected to ease after October 5.

Why it matters

This is a split-screen weather system: saturated ground and intense downpours in the south, sharper winds and a fast temperature drop farther north and east. The forecast specifically flags risks for travel, transport, autumn harvesting, coastal aquaculture and shipping.

In the heaviest-hit pockets, rain could arrive quickly enough to raise the risk of flash floods and geological hazards. At the same time, temperatures may fall by 4–6°C, and locally by 8–10°C, making the change more than a wet holiday forecast.

The practical outlook is straightforward: disruption is most likely where heavy rain overlaps with exposed roads or steep terrain, while maritime conditions become more difficult as the northern seas reach their strongest winds on October 4 and 5. No actual damage or cancellations have been confirmed.
