Egon is blowing over Germany from the west and brought hurricane-force winds to Saarland and Rhineland-Palatinate.
By Friday morning, Egon had already covered parts of Germany in snow, uprooted trees and shut down streets.
The German Weather Service (DWD) says that certain areas may get up to 30cm of snow within hours.
Frankfurt, Leipzig, and Dresden airports have cancelled flights.
One driver died in an accident, likely due to slippery roads, in Schleswig-Holstein. Another driver was also reported as killed in a weather-related accident in Hesse.
End of live blog, 5.20pm: The Local followed the damage caused by the storm throughout Friday, but now it's time to wrap up the live blog as we head into the weekend.
Dozens have been injured in weather-related accidents - at least two of which were deadly - and neither weather nor rail services have yet given the all-clear about stormy conditions.
Thousands in Baden-Württemberg and Bavaria were left without power, while children in various parts of the country were unable to make it to school.
Frankfurt Airport cancelled 125 flights, while Dresden and Leipzig airports also had some cancellations.
Looking to the weekend, the DWD expects more snow in many areas, especially in mountainous regions like the Alps. And drivers are warned to be cautious of black ice on roadways.
Here's a look at the Saturday forecast below, and stay safe!
Another fatality reported, 3.20pm: Near Fulda in Hesse, a 21-year-old driver was killed when he tried to overtake another driver on a "glass-like" roadway, according to Hessenschau.de. His car started to swerve and he hit another oncoming vehicle. The 70-year-old woman in the other car was lightly injured.
No 'all-clear' for train travellers yet, 3.15pm: In various parts of the country, train travel has been delayed due trees falling onto tracks and other obstructions caused by the storm. A railway spokesperson told Bild newspaper at about 3.15pm that they could not yet give travellers the all-clear.
"Our colleagues are working at full speed to retrieve fallen trees from platforms, repair overhead wires, and make the routes drivable again," the spokesperson said.
"We cannot completely give the all-clear to passengers because the snow front is still underway."
2.15pm: The roofs of some houses have been damaged in the storm, including the one pictured below in Hanau, Hesse.
And the one below in Stuttgart.
Snowplow drivers battle Egon, 1.30pm: Snowplow driver Uwe Deppe in Lower Saxony tells DPA about his determination to make driving easier amid storm Egon.
"I get every street clear," Deppe said. "At the end, we always win the battle against snow and ice."
So far the 60-year-old has been working through the night, and by mid-day there appeared to be no end in sight. Deppe has already driven 400 kilometres on the 10-kilometre stretch he's been clearing between Bad Harzburg and Torfhaus.
"We will drive until the street is black again."

12.20pm: A driver along the Autobahn 7 in northern Schleswig-Holstein died in an accident, most likely due to slippery roads, police said.
Numerous streets in Bavaria and the Thuringian Forest area were blocked by fallen trees or trucks that were stuck. According to Thuringia officials, these obstacles also meant that schools buses could not bring children to school.
"The situation is chaotic," said a spokesman from the area of Schmalkalden-Meiningen.
In the Bavarian town of Kirchenthumbach, one school bus was blown by a gust of wind into a roadside ditch, but no one was injured.

11.30am: The DWD posted an image on Twitter showing where German residents can expect to experience the fiercest weather conditions. The more red area means "high risk of bad weather", while the orange area means "bad weather risk".
