Typhoon Dolphin lashed Japan's southern region with strong winds, causing injuries and blackouts, and was then headed toward China, where authorities have closed ports and stepped up preparations.
The storm is the fourth typhoon to reach China this summer, according to the National Meteorological Centre. By Friday morning, it was about 820 kilometers off China's east coast, with landfall expected between Zhejiang province and northern Fujian from Sunday afternoon through Monday morning.
Coastal provinces have suspended ferry routes, halted construction and evacuated fishermen. Drones and artificial intelligence have been deployed to patrol the sea and monitor the approaching storm.
In Japan, the typhoon has caused injuries and power outages across the south, though the full extent of the damage has not yet been reported.
