Cold wave in Bonn: Be careful, there is a risk of black ice and frost!

Cold wave in Bonn: Be careful, there is a risk of black ice and frost!

What's going on in Cologne and the surrounding area? Today, December 29, 2025, a strong winter brings a lot with it. Morning temperatures drop to minus six degrees, making the streets and sidewalks slippery. Fog near the Rhine also leads to dangerous freezing conditions. According to reports from ga.de So far, no relevant icy accidents have been reported by the police or fire brigade, but drivers, cyclists and pedestrians should still be particularly careful.

The warning voices from the German Weather Service (DWD) emphasize that freezing drizzle is the main danger today. The maximum temperatures only rise to minus one to plus three degrees, which means that the permanent frost continues. For Tuesday night it will initially remain overcast, with local freezing drizzle and snow grit in the mountain regions and in the east of North Rhine-Westphalia.

Black ice creates danger on the roads

How weatherhazards.de reported, the weather situation remains characterized by a relatively cold air current from the Atlantic. Severe frost temperatures are to be expected, especially in the higher altitudes and mountain regions. The DWD not only warns of slippery conditions due to freezing drizzle, but also mentions light to moderate frost conditions at night.

Across Germany, including the Cologne area, many roads remain uncomfortably slippery. The quiet but frosty night has already led to several ice-claw accidents. That's what she reports Time that in Mecklenburg-Western Pomerania the police recorded 15 slippery-related accidents the evening before, while motorway sections in Lower Saxony such as the A1 near Wildeshausen were affected by a serious traffic accident. Many a colleague from the fire brigade must have started sweating.

The weather could persist again on New Year's Eve: the clouds are thickening and rain or drizzle is to be expected. Even if the temperatures rise to two to five degrees on New Year's Eve, it remains exciting from a meteorological point of view. In the mountains we even have to expect snow or freezing drizzle, which could increase the risk of slippery conditions on New Year's Eve.

Protection from shivering

The reports confirm that good hands are required in such wintry conditions. Cyclists and pedestrians should pay particular attention to the conditions and, if possible, concentrate on the rules of the road. With the low temperatures and the increased risk of slippery conditions, winter is not without its challenges. A little caution never hurts – for everyone!
