Typhoon Hagupit hit China's eastern coast on Tuesday before weakening and heading north toward the Korean Peninsula's western coast.

The typhoon made landfall in Yueqing, Zhejiang province, at about 3:30 am on Tuesday, moving north past Shanghai and downgrading to a tropical depression at 5 am on Wednesday, said the National Meteorological Center.

Zhejiang, Shanghai and Jiangsu have since Tuesday experienced heavy rainfall because of the typhoon, with precipitation in Yongjia and Yueqing in Zhejiang being the highest - between 400 to 552 millimeters.

The meteorological center said that the tropical depression was later upgraded to a tropical storm at 10 am after it moved to the Yellow Sea, with wind speeds of up to 18 meters per second.

Typhoon Hagupit is presently headed northeast at a pace of 30 kilometers per hour and will land at the North Korea in the evening.

The center has issued a typhoon "blue" warning, which requires ships working out at sea to return to port.
