　　On the early morning of November 21, the news of the first snow in Beijing filled WeChat Moments. Affected by the strongest cold air since the beginning of autumn in our country, snowflakes visited the "imperial capital" at night (20th).

　　According to China Weather Network, around the evening of the 20th, the rain in Beijing gradually turned to snow, and the snow was the heaviest from the night of the 20th to the morning of the 21st.

　　During the precipitation process, there will be moderate to heavy snow in most areas of Beijing, with a cumulative precipitation of 8-10 mm; there will be local blizzards, with a cumulative precipitation of 12-20 mm. On the morning of the 21st, most areas of Beijing will see 3-5 cm of snow, accompanied by bad weather such as icy roads and low visibility.

　　Due to the large snowfall range and amount, it will become the first snowfall in Beijing this winter.

　　According to statistics, since the beginning of meteorological records, the average first snow date in Beijing has been November 29. In the past ten years, only 2004 has arrived as scheduled. This year's first snow is a week earlier than the average first snow day in Beijing.

　　The cold air will not only bring precipitation to Beijing, but also bring significant cooling.

　　According to the Beijing Meteorological Bureau, the snowfall gradually ended in the afternoon of the 21st, but the temperature dropped significantly after the snow. On the 21st-22nd, there will be a northerly wind of about 4 degrees, and gusts of 6 and 7 degrees in Beijing. The expected cooling range on the 21st-24th can reach 8~ 10 degrees Celsius. On the 22nd-24th, the highest temperature during the day is -3~ -1 degrees Celsius, and the lowest temperature at night is -9~ -10 degrees Celsius. According to China Weather Network news, the highest and lowest temperature in Beijing was 6.6 degrees Celsius before, and the temperature will hit new lows in the next few days.

　　According to the Beijing Municipal Transportation Commission, the snowfall and cooling weather will add congestion to the busiest Monday morning rush hour. Beijing will start a plan in advance to dispatch ground buses, taxis and subway operating units to allocate sufficient capacity and strengthen traffic diversion.

　　At present, the bus has prepared 250 motor vehicles, which can be put into operation at any time depending on the passenger flow. The traffic control department will strengthen the traffic guidance of key parts such as main roads and ring road exits, strengthen the linkage with civil aviation and railway departments, and keep abreast of the entry and exit of passengers.

　　Among them, Beijing-Tibet and other highways have become the key areas of concern when snowfall cools down, and the transportation department will open the on-site headquarters in time to take measures such as limited viewership, circuit breakage and diversion to avoid large-scale detention.

　　According to the Beijing Municipal Transportation Commission, 16 traffic headquarters have been established in Beijing, and 1,654 sets of equipment and 16,000 tons of snow melting agent have been issued in place. Curves and ramps in mountainous areas will be sprinkled with "antifreeze" in advance to avoid armor piercing.

　　At 23:10 on the 20th, the Beijing Meteorological Observatory issued a yellow warning for road icing. The Municipal Meteorological Bureau reminded: From November 20th to November 21st, there will be obvious rain and snow, and the roads will be slippery. Please minimize or choose public transportation and pay attention to traffic safety.

　　In addition, surging news (www.thepaper.cn) learned from the Beijing Municipal Transportation Commission that Beijing has launched the emergency mechanism in advance, deploying the city's snow and ice shoveling and strong wind cooling work.

　　At present, snow removal and ice shoveling work has been subcontracted in various places. Snow removal and fallen trees are the responsibility of the Municipal Landscaping Bureau; snow removal in rivers and lakes, cleaning debris on rain grates, etc. are the responsibility of the Municipal Water Affairs Bureau; social units and community property companies are also involved in snow removal work.

　　At the same time, Beijing will co-ordinate heating units to ensure that residents' room temperatures meet standards. Public security departments and district, street and township governments have stepped up home heating inspections to prevent carbon monoxide poisoning accidents. Development, reform and power departments have strengthened power supply, focusing on emergency repair of power facilities damaged by disasters.
