Germany is experiencing significant winter weather with snow and rain moving in from the west, causing widespread traffic disruptions and a risk of black ice, particularly in the southwest where precipitation is falling on frozen ground. The German Weather Service (DWD) reported heavy snowfall in several states, including North Rhine-Westphalia, Hesse, Rhineland-Palatinate, and eastern Bavaria, with accumulations of up to 20 centimeters in six hours in mountainous regions. A severe accident occurred on the A2 in Brandenburg when an LKW skidded on snow, resulting in serious injuries and a highway closure. The Alps are expected to receive the most snow, with up to 40 centimeters possible by Friday morning. Temperatures are ranging from minus three to plus five degrees Celsius, with some areas reaching up to eleven degrees.
