Heavy snowfall and strong winds snarled traffic across the Czech Republic over the weekend. Most roads are covered with a layer of wet snow and slush; drivers also have to face strong winds, snowdrifts and subzero temperatures. Several accidents happened along the major D1 motorway between Prague and Brno on Saturday, causing delays. The authorities strongly advise drivers to use tire chains in the country’s mountainous regions in northern and eastern Bohemia. Bad weather is expected to last well into the coming week.
