The meteorological station of Nyingchi City, Xizang, issued a yellow snow warning signal at 18:00 on February 7: It is expected that there will be snow showers in most cloudy days in Nyingchi from 20:00 on February 7 to 20:00 on August 8, light to moderate snow (rain) in most of Motuo and some towns in Bomi, moderate to heavy snow in Sejila, Demla and Mila Mountains, and heavy snow (10-20mm) in Duoxiong La and Galongla, accompanied by Level 4 to 7 instantaneous gusts. Defense measures: Significant snowfall accompanied by cooling and strong winds. Pay attention to preventing the adverse effects of blizzard weather on major projects, energy supply, and power communication facilities. In high-altitude pastoral areas, please strengthen cold prevention and insulation; Snowfall is more obvious in high-altitude mountainous areas, with a temperature drop of 3-6 ℃ after snowfall. The snow and ice formation on the road surface are prone to worsen. Please ask the traffic and transportation management departments to do a good job in traffic safety control; Duo Xiong La and Ga Long La are experiencing heavy snowfall, with the landing area overlapping with the previous snowfall height. The snow depth will further increase, and there is a higher risk of secondary disasters such as avalanches and collapses. Therefore, it is necessary to strengthen the inspection and elimination of hidden disaster points.
