A key expressway linking Warsaw with Gdańsk was temporarily blocked after heavy snowfall left trucks stranded on icy inclines, causing significant delays. Although the route has since been cleared, strong southerly gales pushed up water levels in northern regions, prompting heightened readiness among units of Poland’s Territorial Defense Forces. In the northern city of Elbląg, flood barriers were deployed along the Elbląg River, and authorities canceled the city’s New Year’s Eve celebrations as a precaution. Meteorologists warned of bitter cold and the possibility of blizzard conditions, though weather is expected to gradually improve later this week.
