Jeju has weathered the worst of the season's 14th typhoon as Typhoon Chanthu moves away in a northeasterly direction.
According to the Korea Meteorological Administration, the typhoon came closest to the island at around 7 a.m., Korea time, on Friday, passing 60 kilometers south-southeast of the city of Seogwipo.
The indirect effects of the typhoon started on Jeju early this week.
More than 1,000 millimeters of rain led to some 60 reports of structural damage since Monday.
However, the direct effects hit overnight.
Trees and streetlights were uprooted, roads and farmland submerged, and firefighters were called to respond to 16 reports of flooded drainage systems.
But according to the Disaster and Safety Countermeasures Headquarters, no injuries or deaths were reported.
Twenty-three flights to and from Jeju have been canceled for Friday, as well as 48 ferries on 29 routes connecting the island and other parts of the country.
While the worst has passed, the weather agency is keeping warnings in place for Jeju and regions along the eastern south coast as torrential rain is expected to continue at a rate of 50 millimeters an hour throughout the day.
As Typhoon Chanthu continues on course north-eastward along the Strait of Korea, Busan and Gyeongsangnam-do Province are preparing for rougher conditions.
The typhoon is forecast to pass 160 kilometers southwest of Busan at around 4pm.
A typhoon alert remains in place for Busan and is being expanded to some parts of Jeollanam-do Province and the Gyeongsang provinces.
Typhoon Chanthu is expected to reach the Japanese city of Osaka overnight.
