Dec. 06, 2013 -- "A major icing event is forecast through Friday across portions of the southern Great Plains toward the Lower Ohio Valley, where Winter and Ice Storm Warnings are in effect," reported the National Weather Service. Heavy snow and ice is expected to cut power for prolonged periods of time throughout the region.
In Europe, hurricane-force winds have left hundreds of thousands without power on Friday as high tides rise threatening the worst storm surge in decades.
Emergency services across the region battled overnight to sandbag sodden dykes, evacuate flooded harbour areas and repair damage from toppled trees that crashed onto houses, roads, train tracks and power lines.
Atlantic storm "Xaver", having barrelled across Britain, where two people died Thursday, packed winds of up to 158 kilometres (98 miles) per hour as it hit Germany, also battering the Netherlands, Poland and southern Scandinavia.
Blackouts hit 400,000 homes in Poland and affected 50,000 people in Sweden, while thousands of air passengers were stranded as flights were cancelled at Amsterdam, Berlin, Hamburg, Gdansk and other airports.
The highest tidal surges in decades -- due to the combined effect of strong winds and a large tidal surge -- smashed into dykes in northern Germany and the Netherlands, which however reported no major breaches.
