The Korea Meteorological Administration forecast heavy rain to fall in South Korea from Friday, with precipitation especially heavy on Jeju Island and in areas along the southern coast.
According to the KMA, as cold air from the northwest clashes with warm air from the south, heavy rain will begin to fall from the early hours of Friday, focused on the southern region, including North and South Jeolla provinces, South Chungcheong Province, South Gyeongsang Province and Jeju Island.
Later Friday morning, rain clouds will expand into the rest of Korea.
Due to warm and humid southerly winds, which will directly impact the southern parts of Korea, including Jeju Island, heavy and intense rainfall will be focused on that part of the country.
Jeju Island can expect hourly rainfall between 30 and 50 millimeters, while other parts of the southern region can expect hourly rainfall of up to 20 mm. The rain will stop in the southern region late Friday night.
Accumulated rainfall on Friday is expected to range from 50 to 100 mm on Jeju Island, while other parts of the southern region may see totals ranging from 10 to 40 mm.
Although the rain is expected to stop in the southern region on Friday, the KMA said clouds will linger in the Greater Seoul region, Gangwon Province and North Chungcheong Province on Saturday, bringing intermittent rain showers. Inland parts of North Jeolla Province and some regions in South Chungcheong Province may also see occasional rain on Saturday.
Rain is expected to continue in these three regions but not in the southern region on Saturday due to northwesterly cold winds that are expected to intensify a low-pressure system hovering above the area, according to the state weather agency.
Between Friday and Saturday, accumulated rainfall is expected to range between 10 and 40 mm in the Greater Seoul region, while Gangwon Province can expect to see a total of between 10 and 50 mm.
In addition to heavy rainfall, the KMA forecast strong winds from Friday morning until early Saturday. Eastern parts of Gangwon may see strong winds until Saturday night. A strong wind advisory is expected to be issued for Jeju Island and eastern parts of Gangwon Province from Friday morning until Saturday.
Due to the rain and strong winds, the KMA added that average nationwide temperatures will also drop below the historical average from Friday until Sunday.
In Seoul, the low temperatures on Friday and Saturday are expected to reach 15 degrees Celsius and 12 C, respectively, while the highs are expected to reach 16 C and 15 C.
Higher temperatures are expected Sunday, with an average for the day of 20 C. Warmer-than-average temperatures can be expected from Monday.
