Weather reports predict more than a foot of snow from Virginia to the New York area, threatening travelers and retailers in what is normally a big shopping day. The storm first hit Alabama, Georgia, and Florida with heavy rainfall, but the big weather is supposed to hit the East Coast Saturday afternoon, with more than a foot of snow forecast for New York City. "A snowstorm like this is not good news," said weather researcher Scott Burnhardt. "This is 'Super Saturday,' we're talking about well over $1 billion traded on this day." Delta Airlines has also canceled all Saturday flights from Philadelphia, Richmond, Va., and Washington, and a government forecaster predicted the I-95 will "be a mess." The governor of Virginia has already declared a state of emergency.
