Strong winds from the indirect effects of Typhoon Krovanh delayed flights and halted some ferry services on Jeju Island.
High-wind advisories were in effect across all of Jeju as of 3 p.m. on the 4th, the Jeju Regional Office of Meteorology said. Gusts exceeding 20 meters per second were recorded in several areas.
As of 3:30 a.m., the strongest gusts of the day reached 26.9 meters per second at Saebyeol Peak, 26 meters per second at Marado, 25.4 meters per second at Jigwido, 24.8 meters per second at Udo, 24.6 meters per second at Sajebi on Hallasan and 24 meters per second at Gangjeong.
A high-wind warning and a wind-shear warning were also issued for Jeju International Airport, disrupting flight operations. A total of 84 flights — 40 departures and 44 arrivals — were delayed through 4 p.m., according to the Korea Airports Corporation's Jeju office. A total of 505 flights were scheduled for the day, including 253 departures and 252 arrivals.
The delays did not lead to widespread cancellations. "A high-wind warning has been issued, but the winds are easterly, so operations are not disrupted enough to force cancellations," an airport official said.
Sea routes were also affected. With swell advisories in force in waters off Jeju, some ferry services linking the island with Jindo and Samcheonpo were canceled. All ferries running between the main island and Gapado and Marado were canceled.
Wind damage was reported as well. The Jeju Fire Safety Headquarters received 13 reports related to the weather advisories through 1 p.m. In Jeju City, roadside trees and median barriers were toppled and traffic lights were damaged, prompting safety measures.
All seven hiking trails in Hallasan National Park were closed because of the winds, and swimming was banned at 12 designated beaches on the island. Jeju Province moved the venue for a gender equality week ceremony scheduled for the 5th from Buksugu Plaza in Jeju City to the Kim Man-deok Memorial Hall.
The weather agency forecast that gusts of 20 meters per second or more would continue in parts of Jeju for some time. Winds could strengthen to 26 meters per second or more in areas under high-wind warnings and to 30 meters per second or more in mountainous areas.
"The high-wind and swell advisories could remain in place for an extended period, through the 8th," a weather agency official said. "People should take care with facility management and safety, and vessels sailing or fishing need to be especially cautious."
