The latest forecasts suggest Bavi is likely to come ashore near the border between Zhejiang and Fujian provinces.

To reduce the risks and shore up maritime safety, Zhejiang's maritime authorities activated a Level IV emergency response for typhoon prevention at 10 a.m. Monday and have since rolled out a full set of flood- and typhoon-preparedness measures. 

These include guiding construction vessels and non-powered vessels to map out their evacuation routes ahead of time and move in an orderly way to safe anchorages and sheltered waters.

For key offshore projects such as the Tongsu-Jiayong Hangzhou Bay Cross-Sea Bridge, authorities have pressed contractors to take protective steps, including evacuating personnel and reinforcing equipment.

For passenger transport, 53 ferry routes and 117 passenger vessels in Zhejiang had been suspended because of strong winds as of 6 p.m. Tuesday. Schedules will be adjusted further as the typhoon develops and sea conditions change.
