What is freezing rain?
When the strong cold air meets the warm and humid airflow from the south, the cold air is inserted under the warm air, which causes the temperature in the near-surface layer to drop below zero. Moist warm air rises to form clouds, which in turn produce precipitation. Freezing rain is a mixture of ice and water, which is a kind of precipitation that freezes immediately after colliding with an object with a temperature below 0℃.
Raindrops below 0℃ remain supercooled in air slightly below 0℃, and their appearance is similar to that of ordinary raindrops. However, when they come into contact with objects with a temperature below 0℃, they will immediately freeze into a smooth and transparent ice layer, forming a so-called glaze. Severe rainstorm will bring many problems and harms to society. It can break trees and telephone poles, causing communication and power interruption. Road and railway traffic will also be hindered and even threaten the flight safety of aircraft.

1. Travel safety: Freezing rain will freeze the ground and increase the danger of walking and driving. Residents should pay attention to check the road conditions before going out, choose a safe walking route or postpone their trip. If you must travel by car, slow down and keep a safe distance, and pay attention to avoid sudden braking.
2, indoor warmth: freezing rain weather is usually accompanied by low temperature, residents should pay attention to indoor warmth. Adjust the indoor temperature reasonably, wear warm clothes, use heating equipment or electric blankets, etc.
3. Prevention of power outage: Freezing rain can easily lead to wire icing and increase the risk of power outage. Residents should pay attention to safety when using electrical appliances to avoid excessive use of electrical equipment. If power failure or abnormal line is found, it should be repaired in time or contacted with the power supply department.
