Central and southern Korea could see more than 200 mm of torrential rains between Wednesday afternoon and Thursday morning, as this year's seventh typhoon Khanun moves north toward the peninsula, the Korea Meteorological Administration forecast Monday.
The typhoon is not strong but a great deal of rain is expected.
Khanun arose about 870 km southeast of Okinawa, Japan around 3 p.m. Monday. It is moving north in the direction of Jeju at a speed of 50 km per hour with sustained winds of 18 m per second.
The typhoon will reach waters near Jeju on Wednesday afternoon and then turn toward the West Sea, the KMA predicted. It will be the first typhoon to affect Korea this year.
Meanwhile, seasonal rain will fall in some parts of Jeju and the south until Tuesday. The central part, including Seoul and Gyeonggi Province, will also be wet on Tuesday night, when hot and humid air flows in from the typhoon, and stay that way till Thursday.
