According to weather forecasts, the tropical storm will make landfall on Sunday afternoon, July 24, in the vicinity of Ningbo and Shanghai, two of the world's largest coastal cities.
In Shanghai, China's largest city, the wind was blowing hard on Sunday morning, but the rain was still limited.
All flights were suspended at the city's two international airports, dozens of trains were suspended and traffic was suspended in the ports of Shanghai and Ningbo.
Some theme parks, such as Shanghai Disneyland, have been closed, and Chinese authorities have called on residents to avoid outdoor activities.
And in Henan province, where unprecedented flooding this week has killed at least 58 people, authorities continue to work to remove car bodies and debris from roads to reopen them.
More than 495,000 people have been evacuated, according to the Henan government; The floods caused billions of dollars in damages.
The China Meteorological Agency expects the typhoon to ease over land, but it will bring heavy rains for days in eastern China, including in flooded areas.
The Bureau of Meteorology said: "Extreme care must be taken to prevent disasters that may result from extreme rains" accompanying Cyclone N-Fa.
China usually witnesses a rainy season, but record rains in Henan have raised doubts about the ability of Chinese cities to cope with these weather phenomena, which experts expect will increase in frequency and intensity due to climate change.
Henan Province, like much of China, has rivers, dams, and reservoirs, many of which were erected decades ago; In order to contain the flow of water and irrigate agricultural areas, but its construction dates back decades, while the continuous urbanization of the city puts pressure on the drainage systems.
