CCTV News:The Central Meteorological Observatory issued a weather bulletin. During the day, there was snowfall in Yantai and Weihai, Shandong Province. In the next three days, the national temperature will continue to be low, paying attention to the impact of strong cold air on the central and eastern regions from the 18th to 20th. The high altitude areas in western Guizhou pay attention to the icing effect of freezing rain on transmission lines, wind farm fans and other facilities. China’s offshore waters are windy, and we are concerned about the harm of strong winds at sea.
