On the evening of February 20th, in Xi'an, Shaanxi Province, freezing rain suddenly descended, causing slippery road conditions and leading to a multiple-vehicle collision on the southern section of the West Third Ring Road, involving as many as dozens of vehicles. After more than two hours of timely rescue efforts by traffic police and firefighters, all drivers and passengers were safely rescued, and the accident did not result in any casualties.

On the morning of the 21st, the Xi'an Meteorological Department responded, stating that this freezing rain hasn’t been spotted since 2001 in Xi'an.

"Freezing rain" is a mixture of ice and water. When this mixture descends to the ground and comes into contact with objects with temperatures below zero degrees Celsius, it immediately freezes into a smooth and transparent layer of ice, commonly referred to as freezing rain or ice glaze. Freezing rain typically occurs in winter or early spring, with more occurrences in the south than in the north. Freezing rain is a dangerous weather phenomenon that can cause extremely slippery road conditions. Additionally, freezing rain can have a significant impact on crops, resulting in reduced yields or even crop death.

2月20日晚，陕西西安，冻雨突然降临，路面湿滑难行。西三环南段发生多车连环相撞事故，涉及车辆多达数十辆。经过交警及消防2个多小时及时救援，司乘全部脱困，事故并未造成人员伤亡。
21日上午，西安气象部门回应称，本次冻雨过程为2001年以来西安首次冻雨过程。“冻雨”是冰与水的混合物，这种混合物在下降到地表后，与温度低于零度的物体碰撞，就会立即冻结成外表光滑而透明的冰层，人们通常把这种冰层称为雨凇或冰凌。冻雨通常出现在冬季或初春季节，南多北少。中国最常出现冻雨的地区有贵州省，湖南省、江西省、湖北省、四川省等地的高海拔山区和丘陵地带。
冻雨是一种危险的天气现象，它的出现会导致路面变得非常湿滑。它不仅给人们的出行和生活带来很多不便。还会对车辆和公共交通工具造成影响。如果冻雨持续不断，冰层不断增厚，对建筑、电力设施、通信设施等造成严重破坏。此外，冻雨还会对农作物造成很大的影响，导致农作物减产甚至死亡。
