The isobar spacing between the high pressure over the west of the Korean Peninsula and the low pressure to the east is tightening, causing strong winds along the coast and high waves in the sea. Currently, a strong wind advisory has been issued for the southwestern coast of Jeolla, the five islands of the West Sea, Ulleungdo, and Dokdo, while a rough sea advisory has been issued for the West Sea, the waters around Jeju, and the far east of the East Sea.
