Snow continues piling up on the streets Saturday, March 8, 2008, in Columbus, Ohio. A foot of snow buried parts of the Ohio and Tennessee valleys early Saturday, shutting down travel and many public events. Blizzard warnings remained in effect in Ohio, with winter storm warnings from Tennessee to upstate New York and northern Maine. Wind up to 35 mph whipped the snow and cut visibility to less than a quarter mile in places, the weather service said. [Agencies]
