SEOUL » A typhoon that battered the Chinese coast has weakened into a tropical storm as it pushes toward the Korean Peninsula, where some South Korean flights were canceled due to strong winds and rain.

Tropical Storm Chan-hom is packing winds of up to 52 miles per hour. According to the U.S. military’s Joint Typhoon Warning Center, it was centered over the Yellow Sea about 185 miles southwest of Seoul Sunday morning and is forecast to move across the Demilitarized Zone separating North and South Korea late Sunday or early Monday. 

It is then expected to dissipate over North Korea. 

No casualties have been reported from heavy rains that pounded areas south of Shanghai in China on Saturday. Some 1.1 million were evacuated as a precaution and about 600 flights were canceled in eastern China.

Chan-hom made landfall in Zhoushan city, Zhejiang province, early Saturday evening, Xinhua reported. All passenger ships and 7,300 coaches suspended services, the news agency said.

In Shanghai, typhoon orange alert was lifted Sunday and subway-train service resumed.

Twenty-two people were reported injured on the southern Japanese island of Okinawa as Chan-hom swept through the area before heading for China, Kyodo reported.

Meanwhile, Typhoon Nangka, with top winds of 127 mph, is following a track that may menace Japan later this week. The Category 3 storm was about 1,000 miles east-southeast of Kadena Air Base on Okinawa on Saturday.

Nangka may slow on its track delaying its approach to Japan until late this week, forecasters said. It, like Chan-hom, will likely bring heavy rains.
