The typhoon will bring heavy or torrential rain to five provinces, Shanghai and Taiwan over the next three days, the meteorological center said.
Some coastal areas may see rainfall of 250 millimeters (9.84 inches), it said.
Another typhoon was blowing east of the northernmost Philippine province of Batanes on Sunday with sustained winds of 130 kilometers (81 miles) per hour and gusts of 160 kph (100 mph), but was too far out in the ocean to affect any part of the country.
Typhoon Danas may blow toward southern Japan later this week if it does not change direction, according to the Philippine weather agency.
