Rain and strong winds swept across most parts of the country Saturday, a day ahead of the summer solstice, prompting authorities to urge caution over potential safety hazards and damage to facilities.

The Korea Meteorological Administration (KMA) said that the rain falling nationwide under the influence of a stationary front and a low-pressure system is expected to continue through Saturday evening, though precipitation is likely to ease in many areas in the afternoon.

Some areas in the Seoul metropolitan region, central Korea and northern North Gyeongsang are expected to see rain continue until late at night, while precipitation is forecast to persist through Sunday morning in mountainous areas and coastal regions of Gangwon.

From 6 p.m. Friday to 6 a.m. Saturday, accumulated rainfall reached 137.5 millimeters (5.4 inches) on Mount Halla on Jeju Island, 94 millimeters in Sangju in North Gyeongsang, 88 millimeters in Gongju, South Chungcheong, 81 millimeters in Samcheok, Gangwon, 64.5 millimeters in Boseong, South Jeolla, 60 millimeters in Seoul and 40.5 millimeters in Incheon.

Heavy rain advisories are in effect for mountainous areas of Gangwon, as well as Gongju and Cheongyang in South Chungcheong and Sangju, Yeongju, Yeongdeok and the lowland areas of Uljin County in North Gyeongsang.

Mountainous and coastal areas of Gangwon are expected to receive the heaviest rainfall, with 50 to 120 millimeters forecast. Northern mountainous areas could see more than 200 millimeters of rain, while central mountainous regions and the central and northern east coast may receive over 150 millimeters.

Rainfall of 30 to 80 millimeters is forecast for the Seoul metropolitan area, inland Gangwon, Daegu, North Gyeongsang and Ulleung Island and Dokdo. The Chungcheong region, North Jeolla, Busan, Ulsan and South Gyeongsang are expected to receive 20 to 60 millimeters, while Gwangju, South Jeolla and Jeju are forecast to see 5 to 40 millimeters.

Heavy downpours of 20 to 50 millimeters per hour are expected through Saturday morning in northern mountainous areas of Gangwon and parts of the Gyeongsang region. Mountainous and coastal areas of Gangwon are likely to continue experiencing heavy rain of 20 to 30 millimeters per hour after the morning.

The KMA warned that strong gusts, thunder and lightning may accompany the rainfall, urging residents to exercise caution.

Coastal areas of Jeolla and South Gyeongsang, as well as Jeju, are expected to experience strong winds with gusts exceeding 70 kilometers per hour (45 miles per hour) through Friday afternoon. Mountainous areas of Gangwon could see gusts of up to 90 kilometers per hour.

Cruise tourists holding umbrellas are seen exiting the Seogwipo Gangjeong Cruise Terminal on Jeju Island on June 19 as a heavy rain advisory was issued for the area.

As of Saturday morning, strong wind advisories were in effect across all of Jeju. High wave advisories have also been issued for waters off the island, and Jeju International Airport recorded a maximum instantaneous wind speed of 21.4 meters (70.2 feet) per second.
