The strongest typhoon to hit Shanghai since at least 1949 flooded roads and uprooted trees, knocked out power to some homes and injured at least one person as it swept over the financial hub on Monday.

More than 414,000 people had been evacuated ahead of the powerful winds and torrential rain. Schools were closed and people were advised to stay indoors.

One elderly man was injured by a falling tree on Shanghai's Chongming Island, according to state media. He was taken to hospital for treatment.

Typhoon Bebinca made landfall around 7:30am in the Pudong business district with winds of 151 kilometres an hour near its centre.

Torrential rains flooded roads in the district, according to images broadcast by state media.

Elsewhere in Shanghai, uprooted trees and fallen branches blanketed some roads and sidewalks. As the typhoon eased, responders cleared branches and other objects blown around by the storm.

More than 60,000 emergency responders and firefighters were at hand to lend aid in Shanghai.

The State Flood Control and Drought Relief Headquarters on Sunday activated the Level IV emergency response for Anhui Province and raised the response in Shanghai and Zhejiang to Level III.

Bebinca led to flight cancellations in Shanghai and the suspension of passenger ferries.

Shanghai Railway Station also suspended passenger trains on several routes passing through the city from Sunday to Monday.

Shanghai Disneyland, Disneytown and Wishing Star Park remained closed on Monday, with the two resort hotels providing services to in-house guests, the Shanghai Disney Resort said in a statement, adding that normal operations were expected to resume from Tuesday.

Authorities said winds uprooted or damaged more than 10,000 trees and knocked out power for at least 380 households, damaging four houses.

At least 53 hectares of farmland were flooded.

The typhoon weakened as it moved inland, dousing parts of Jiangsu, Anhui and Zhejiang provinces. (AP/Xinhua)
