The torrential downpours and gale-force winds has led China on Monday to cancel hundreds of flights in Beijing and shut schools and tourist sites.

As the Chinese capital faced its biggest storm this year, city authorities issued warnings to residents to stay home.

As much as 100 millimeters of rain is predicted through the day in some areas, and aviation tracker VariFlight recorded some 700 flights canceled at the city’s two airports.

Weather authorities cautioned of “extreme rainstorms” as well as thunder and lightning from late Sunday to Monday evening in Beijing and neighboring areas.

A landslide was recorded in one of the city’s northern districts, with state broadcaster CCTV showing pictures of a road blocked by fallen rocks. Heavy rain was holding up efforts to clear the road, according to state TV.

Children stayed home as the city’s kindergartens, primary and secondary schools closed Monday.

Popular attractions including a part of the Great Wall were also shut, with some districts suspending rural homestays.

Some of Beijing’s automatic driving trains will be operated manually instead, state media said.

Rainstorms also hit neighboring Tianjin city, where state TV showed electric scooters driving through flooded streets and black skies lit up by regular flashes of lightning.

Weather authorities have warned of floods in 14 rivers, including tributaries in Sichuan and Shaanxi.
