By the 18th, more than 300mm of heavy rain is expected in the Chungcheong region, Jeonbuk, and northern inland Gyeongbuk.

From the 20th to 21st, except for Jeju, the rain will temporarily subside, but it will resume nationwide from the 22nd to 24th. Rain is expected mainly in the central region on the 25th and 26th.
