What changed
Cold air is continuing to sweep across central and eastern China from 1 to 4 November, bringing sharp temperature drops, strong winds and widespread rain. Areas north of Nanling are expected to cool by 4–8°C, with some parts of Jiangnan falling by more than 10°C. The Central Meteorological Observatory has kept a blue strong-wind warning in place.
Some inland areas could see force 5–7 winds, with gusts reaching 8–9. Offshore, the Bohai, Yellow Sea and northern East China Sea may face force 7–8 winds and gusts of 9–10. Meanwhile, parts of the Sichuan Basin, Jianghuai and northern Jiangnan face moderate to heavy rain, with local totals of 25–45 millimetres from 1 to 2 November and 25–40 millimetres from 3 to 4 November.
Why it matters
This is a broad weather shift with two practical hazards arriving together: colder air on land and rougher conditions at sea. Outdoor workers and residents will feel the temperature change quickly, while transport operators must contend with strong winds across exposed roads, coastal waters and shipping routes.
Rain will keep moving through central and southern areas rather than clearing immediately. Chongqing, Guangxi, Jiangxi, Hunan, Anhui, Hubei and neighbouring regions are among the places facing further rain through 4 November, with snow or sleet also possible in parts of the north and high-elevation west.
The forecast points to heightened disruption risk, but actual cancellations, damage, injuries and agricultural losses will depend on local conditions. The key signal is persistence: wind, rain and falling temperatures are expected to overlap across several days, leaving transport and outdoor activity vulnerable wherever the heaviest weather develops.
