Typhoon Usagi was grinding westward and expected to make landfall close to Hong Kong late today or early tomorrow. Forecasters had warned earlier that the storm posed a "severe threat" to the southern Chinese city.
Usagi was downgraded from a super typhoon yesterday, when its sustained winds fell below 241 km per hour, after it passed through the Luzon Strait separating the Philippines and Taiwan, likely sparing residents in both places from the most destructive winds near its eye.
By this morning it was about 370 km east of Hong Kong and moving west at 20 kph, the Hong Kong Observatory said. It said the storm would retain maximum sustained winds of 140 kph at 5 am tomorrow after making landfall overnight. The observatory said it would consider raising the No. 8 storm warning signal later today, after issuing the No. 3 standby signal the day before.
Guangdong authorities asked more than 44,000 fishing boats to return to port while neighbouring Fujian Province evacuated more than 80,000 people from flood-prone areas and deployed 50,000 disaster-relief workers, the official Xinhua news agency reported.
Cathay Pacific Airways and Dragonair said flights to and from Hong Kong International Airport would be cancelled from 6 pm today and resume tomorrow if conditions permit. China Southern Airlines, based in nearby Guangzhou, also said it was cancelling flights to and from Hong Kong and other places in China, Xinhua said.
