The Meteorological Administration announced this by holding an online forecast briefing on the snow that will continue until the 18th of the 17th. Forecast analyst Woo Jin-gyu, the forecasting department of the Meteorological Administration, explained the snow forecast.
The snowfall forecast from 3 pm on the 17th to 6 pm on the 18th, the next day, is about 5-10cm in eastern Gyeonggi Province, Gangwon (excluding the east coast), and northern Chungcheong. The Meteorological Administration predicted that there will be places where it falls more than 15 cm. Forecast analyst Woo said, “It is an area that needs preparation because there is a possibility of warning among heavy snowfall warnings.”
The heavy snow warning goes into effect when the amount of snow accumulated for 24 hours is expected to exceed 20cm. In the case of mountain areas, it takes effect when the amount of snow accumulated over 24 hours is expected to exceed 30cm, and the prospect of ’15cm or more’ suggests the possibility of snow that exceeds the mere 15cm. Snow can accumulate around 2~7cm in the metropolitan areas such as Seoul (excluding eastern Gyeonggi), Chungnam, southern Chungbuk, inland Jeonbuk, and northern Gyeongbuk. Forecast analyst Woo added, “There is a possibility that a heavy snow special report will take effect in this region, too.” It will expand to Yeongseo, northern Chungcheong and inland Gyeongbuk.”
In addition, he analyzed that “in the morning of the 18th, cold air from the northwest will quickly become southward, and the snow cloud belt will develop further, so it will snow in southern Chungcheong and northern Jeollabuk-do.”
The snow that falls between the afternoon and night of this day (17th) is in the central region of Korea, which is between the high pressure in the south and the low pressure in the north, and the warm, high-humidity western wind affects the strengthening of snow clouds on the west coast, resulting in strong and heavy snow.
The meteorological agency predicted that between the early morning of the 18th and the morning, the low pressure in the north would descend to the Ongjin Peninsula in North Korea, further developing the cloud zone and strengthening the warm air in the whole, strengthening the snow cloud zone.
The Meteorological Administration also explained that depending on the situation, there may be a snow pattern such as a’guerilla-like torrential rain’, such as heavy snowfall in a small area.
The Meteorological Administration explained that this strong and many snowy pattern is unusual in terms of climate. Forecast analyst Woo said, “There has been periodic snowing in the past, but this strong and much is unusual.”
Unlike the snow on the 12th, the Meteorological Administration also emphasized that, unlike snow on the 12th, it does not melt immediately and freezes as soon as it accumulates during heavy snowfall in subzero temperatures, so it is also emphasized to prepare for traffic conditions and safety.
Snow was forecast again next weekend, 23-24. Forecast analyst Woo said, “(Even in the news of next week’s snow), there will be a lot of water vapor.
The Meteorological Agency said, “The Arctic Ocean ice area is narrowing due to the high temperature of the Arctic. The flow of air coming down between the continental high pressure on the left side of Korea and the eastern cyclone is becoming very strong,” he added. “There is a characteristic that snow can come strongly as the instability increases in the process of deterioration as the incoming air collides.”
The Meteorological Administration announced a heavy snow preliminary warning at 11 am with a briefing.
As of the early morning of the 18th, Seoul and Gyeongnam (Geochang, Hamyang), Chungbuk (Jecheon, Jeungpyeong, Danyang, Eumseong, Jincheon, Chungju, Goesan, Cheongju), Chungnam (Asan, Cheonan), Gangwon (Gangwon central and southern mountains, Jeongseon-Pyeongchang) Hongcheon Pyeongji, Hoengseong, Wonju, Yeongwol, Taebaek), Gyeonggi (Yeoju, Seongnam, Yangpyeong, Gwangju, Anseong, Icheon, Yongin, Hanam, Uiwang, Namyangju, Guri, Suwon, Uijeongbu, Gwacheon), Jeonbuk (Muju, Jinan, It was announced that it would snow on longevity).
