Precautionary advice
1. There was still snow on the morning of the 7th, and the surface temperature was low, which could easily cause snow accumulation and road icing. It is necessary to prevent adverse effects on transportation, power transmission and communications.
2. At present, the branches and leaves of trees are still relatively luxuriant. Strong snowfall and strong winds can easily cause branches to break and trees to fall. It is necessary to remove snow in time and take protective measures for old trees and street trees.
3. Please do a good job in the reinforcement of agricultural sheds and other facilities, and snow cleaning to prevent the sheds from collapsing under the pressure of snow.
4. Reinforce temporary facilities such as simple houses, temporary structures, fences, etc., to ensure that they can withstand snow pressure and wind, and clear the snow on the top in time; timely transfer personnel to safe areas in dangerous places.
5. The temperature will drop sharply from the 7th to the 8th, which will bring certain pressure on the city’s heating, power supply, and gas supply. The relevant departments are requested to do a good job in energy dispatch and supply guarantee.
6. On the 7th, the northerly wind is strong, please do the reinforcement of outdoor structures and billboards, and safety of outdoor high-altitude operations by relevant departments.
