The typhoon is expected to come closest to the Korean Peninsula between early Monday morning and afternoon, bringing up to 60 millimeters of heavy downpour per hour to the southeastern coastal areas.

Up to or more than 150 millimeters of rainfall is forecast for the southern coastal areas in Gyeongsang Province until Monday, with 50 to 100 millimeters for the eastern parts of Gangwon Province.

The weather agency also forecast strong winds of up to 35 meters per second for Jeju Island and the southeastern coastal areas between Sunday night and Monday morning.
