Shanghai was brought to a standstill on Monday by what authorities say was the strongest typhoon to directly hit the Chinese financial hub in more than seven decades, with flights, trains and highways suspended during a national holiday.

Officials in China moved some 414,000 people out of the way in Shanghai before the strongest storm in decades flooded roads and cancelled flights.

Shanghai, China’s financial hub, was hit by the strongest tropical storm in 75 years Monday. The city had closed its seaports and canceled more than 600 flights in preparation for Typhoon Bebinca, which made landfall early Sept. 16 having ripped through the Philippines over the weekend.
