As regions of China battled to recover from severe floods earlier this week, China shut down ports and trains on Saturday as it prepared for Typhoon In-Fa.

According to the official Xinhua news agency, In-Fa is expected to make landfall late Sunday in the eastern coastal province of Zhejiang near Shanghai.

According to China Railway, the typhoon has been given a level III alert, the third highest, and more than 100 trains travelling through the region have been cancelled.

On Saturday, Shanghai officials shuttered certain public parks and museums and advised people to “stop large-scale outdoor gatherings” and stay indoors.

Meanwhile, all container ship docks at Yangshan Port, south of Shanghai, have been shut down, and 150 vessels, including passenger and cargo ships, have been evacuated from the region.

Authorities in central China’s Henan province are gradually cleaning and reopening highways blocked by automobiles and debris after record floods this week killed at least 58 people.

The floods have impacted millions of people, with some being stuck for days without food or water and others being carried to safety in excavator buckets.

According to the Henan administration, more than 495,000 people have been evacuated, and the flooding has resulted in billions of yuan in losses.

Li Changxun, a Henan emergency response official, warned on Saturday that the province will need to clean and disinfect on a huge scale to “ensure the disaster is not followed by an epidemic.”

State media and official social media sites have released photos. Rescue workers continued to shovel mud and remove toppled trees around the province on Saturday.

Torrential rains poured a year’s worth of rain on the hardest-hit city of Zhengzhou in only three days this week, killing at least a dozen people aboard a subway train during rush hour on Tuesday when floods trapped commuters in their compartments.

In-Fa is expected to bring further severe rains to portions of the province in the coming days, according to state media.

For millennias, China has experienced an annual flood season, but the record rainfall in Henan has sparked concerns about how China’s towns might better prepare for unexpected weather events, which scientists believe are occurring with more regularity and intensity as a result of climate change.

Rivers, dams, and reservoirs transverse Henan province, many of which were built decades ago to control floodwater and irrigate the agricultural region, but growing urbanisation has put a pressure on existing drainage systems.
