Heavy air pollution is expected to linger in the city for the next few days. Expect the AQI to be between 150 and 200 through the weekend.
In addition to the smog, heavy fog will settle over the city, most likely during the morning hours, until Thursday. A yellow alert was issued for heavy fog on Tuesday. A handful of flights were canceled at Shanghai's airports on Tuesday due to poor visibility, China Daily reports. So you might want to check your flight's status before you head to the airport tomorrow.
