Thousands of people were forced to evacuate as Typhoon Hinnamnor made landfall in South Korea on Tuesday.
It comes weeks after the capital Seoul and nearby regions were hit by heavy rainfall and flashfloods that killed at least 14 people.
What effect has Typhoon Hinnamnor had?
The typhoon left the Korean peninsula off the southeastern city of Ulsan at about 7:10 am, after landing on the coastal city of Geoje, the Korea Meteorological Administration said.
President Yoon Suk-yeol held emergency response meetings, urging officials to take precautions until the typhoon is completely gone.
Where is Hinnamnor headed next?
North Korea also braced for damage from the typhoon as leader Kim Jong Un presided over a two-day meeting on disaster prevention work, ordering the release of water from a dam near its border with its southern neighbor.
Despite South Korea's repeated requests for notice before releasing water downstream, Pyongyang has remained unresponsive.
The typhoon is expected to head northeast and pass about 400 kilometers northwest of Sapporo in Japan at about midnight on Tuesday.
