Rain and fog enveloped Shanghai's main port area, blocking the entry and exit of dozens of ships. More than 50 ships were affected at Waigaoqiao Port.

At Wusong Port, the visibility at the wharf was less than 500 meters. At Yangshan Deepwater Port, a total of 13 international sailing ships have changed their entry or exit plans due to the heavy fog. In response to situations such as heavy fog causing ships to be stranded and port docking plans to be canceled, the border inspection department quickly launched a severe weather emergency plan.
