The weather turned cloudy on 13 November when a broad cloud band associated with Tropical Storm Chebi covered the south China coastal areas. It remained mainly cloudy with a few rain patches in the following seven days.
A broad band of rain and thunderstorms affected southern China on 21 November. Locally, the weather was overcast with heavy rain and squally thunderstorms. More than 100 millimetres of rainfall was recorded at Wu Kau Tang and Ma On Shan on that day.
The passage of a weak cold front on 22 November brought slightly cooler weather to Hong Kong. Another cold front moved across the coastal areas of Guangdong on 27 November.
