At 23:04 on December 1, the Polish Institute of Meteorology and Water Management issued a warning that dense fog will limit visibility to about 150 metres in Warsaw, raising road‑safety concerns.
Visibility Reduction
Fog in the capital is expected to reduce visibility to roughly 150 metres, creating potentially hazardous driving conditions.
Regional Variability
Some areas may experience even lower visibility—200–300 metres—and the fog can persist for much of the night, with local intensity varying across the city and outskirts.
Road Safety Advice
Drivers are urged to exercise particular caution, especially outside the central district where roads are longer, poorly lit, and sudden local fog concentration can occur.
Air Traffic Status
Air traffic at Chopin Airport remains largely unaffected, with no significant delays reported, though the situation is under close monitoring in line with the IMGW warning.
