On 26 October, heavy fog enveloped the Yangtze lower reaches, with visibility reduced to just 100-200 metres in places. More than 2,500 vessels were stranded in the Nanjing and Zhenjiang areas.

The heavy fog also closed some of the busiest expressways in Nantong, Nanjing and other parts of Jiangsu province. By 11am, Nanjing airport had postponed or cancelled eight scheduled flights from Chengdu, Xiamen, Shenzhen, Kunming, Beijing and Guiyang.

Further inland, Chongqing airport was shut down on the same day due to heavy fog. More than 10,000 passengers were unable to travel to, or depart the city.
