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 (85 kilometers) per hour. According to the U.S. military's Joint Typhoon Warning Center, it is centered over the Yellow Sea about 185 miles (297 kilometer) southwest of Seoul 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.
