The Danish Meteorological Institute issued a Category 1 weather warning for dense fog overnight. This alert covers most of Zealand including Copenhagen. Visibility dropped below 100 meters in many areas.
The warning remained active from Sunday evening through Monday morning. Police in Central and West Zealand expect fog-related issues during morning commute hours.
Authorities urge morning commuters to exercise extra caution. An additional risk notice applies to eastern and northeastern Jutland, though this doesn't carry official warning status.
Weather officials describe Category 1 warnings as covering 'violent' weather conditions. The fog represents a typical autumn weather pattern for Denmark, though its intensity warrants special attention for drivers. Morning commuters should prepare for longer travel times and reduced visibility on major routes.
