Snow and rain are expected nationwide on the 2nd, the last day of the March 1 Independence Movement Day holiday.
According to the Korea Meteorological Administration on the 1st, a low pressure system will pass over the sea south of Jeju, and a trough will approach from the northwest and move across Korea.
At present, due to the easterly wind blowing along the edge of a high pressure system situated over the northern East Sea, snow and rain are falling on the East Coast, and heavy snow is expected in Gangwon.
Specifically, on the 2nd, snow and rain will continue in the Gangwon East Coast, Gangwon mountains, northeastern Gyeongbuk mountains, northern Gyeongbuk East Coast, and Jeju, while the precipitation area will expand to Honam before dawn and to the rest of the country in the morning.
After that, eastern North Jeolla will see precipitation through dawn on the 3rd, Jeju in the morning of the same day, and Gangwon and Yeongnam through the afternoon.
This round of snow and rain will be concentrated in the Gangwon mountains, the East Coast, and Jeju. Expected snowfall is 10–30 cm in the Gangwon mountains (more than 40 cm at maximum), 5–10 cm in the northeastern Gyeongbuk mountains, 3–10 cm on the northern Gangwon East Coast (more than 15 cm at maximum), and 3–8 cm in inland Gangwon and the central Gangwon East Coast.
In addition, 1–5 cm is expected in eastern Gyeonggi, the southern Gangwon East Coast, northern North Chungcheong, northeastern North Jeolla, southwestern Gyeongbuk inland, northern Gyeongbuk (excluding the northeastern mountains), and western Gyeongnam inland; 1–3 cm in central and southern North Chungcheong; and less than 1 cm in Seoul and northwestern Gyeonggi.
Precipitation amounts are expected to be 20–60 mm in Jeju (from the 1st; up to more than 80 mm in the mountains), 10–40 mm on the Gangwon East Coast and in the Gangwon mountains, 5–20 mm in Honam, Busan, Ulsan, Gyeongnam, and the Gyeongbuk East Coast, around 5–10 mm in inland Gangwon, Chungcheong, Daegu, southern Gyeongbuk inland, the northeastern Gyeongbuk mountains, Ulleungdo, and Dokdo, and around 5 mm in the Seoul metropolitan area, the five West Sea islands, central Gyeongbuk inland, and northern Gyeongbuk inland.
The snow this time will be heavy, moisture-laden "wet snow." Damage may occur if structures such as vinyl greenhouses cannot withstand the weight of snow piling up on top, so precautions are necessary.
Also, from the 2nd to the 4th, rough seas strong enough to trigger high seas advisories are expected, mainly in the waters off Jeju, the South Sea, and the East Sea. If you plan to travel by plane or ship, it would be advisable to check in advance whether services are operating.
