Jan. 23, 2007 -- Despite fierce winter storms, weekly sales at the nation's chain stores rose by 0.1 percent last week, the International Council of Shopping Centers said Tuesday.

Compared to the same period last year, sales rose by 4.8 percent, the trade group said.

"Sales inched up over the latest week, but were hurt by soft customer traffic due to some regional weakness as more than half of the U.S. was snow covered," Michael Niemira, the group's chief economist, said in a statement.
