Four people were killed after Typhoon Krosa slammed into Taiwan but the storm weakened as it moved toward mainland China on Sunday.
Two people were also missing in Taiwan, the Disaster Relief Center said in a statement.
As of 8:30 a.m. Sunday, Krosa was centered at sea about 130 kilometers northwest of Keelung on the northern tip of Taiwan. It weakened to a tropical storm with sustained winds of 108 kph, down from 184 kph, the Central Weather Bureau said.
Krosa was forecast to strike China's southern Zhejiang and northern Fujian provinces late Sunday, China's national flood control office said in a notice on its Web site.
