The Seoul metropolitan government announced that approximately 5,300 workers, and 1,116 snow-clearing vehicles and equipment have been mobilized in preparation for the anticipated snowfall of 1 to 5 centimetres, which is expected to continue through early Saturday.

Security cameras installed along the country's western coastal region are being used to monitor snow movement in advance, the city government said.

Lat month, the heaviest snowfall for November in 117 years blanketed Seoul and the surrounding regions, causing injuries, disrupting traffic and cutting off power supplies.

In Seoul's Songpa district, three people were injured and taken to nearby hospitals after a snow fence installed near a construction site collapsed due to snow.

More than 170 households had also experienced a blackout in Seoul's Seongbuk district, as trees likely fell on telegraph poles and electric wires under the weight of heavy snow, according to the Korea Electric Power Corp.

Dozens of other households in Eunpyeong-gu also experienced interruptions to power supplies, reported Yonhap news agency.
