Snow and icy roads are once again complicating traffic around the country. Police along the D1 highway to Brno and the D8 highway to Germany are reporting traffic jams and pile ups. Drivers using the new by-pass around Prague have been warned to expect slow traffic. A number of smaller roads have had to be closed and road maintenance companies say they are manning all available vehicles at the present time. Another 20 to 30 centimeters of fresh snow is expected to fall overnight.
