Skies began to clear in most parts of the city early on Sunday afternoon, and cicadas resumed chirping in the humid heat.

City traffic, which was affected due to closure of some tunnels and expressways and temporary speed limits on certain expressways and bridges over the Huangpu River on Sunday morning, has since returned to normal, the municipal government said on its WeChat account.

All bus operations between the city's downtown and Chongming Island were restored at 2:10 pm, but all ferry lines remained closed at press time.

Operations at the city's two airports, at which more than 500 flights had been canceled and dozens more delayed on Sunday morning, also gradually picked up, according to the airports.
