New York ? Winter storms and worries about war gave consumers more reasons not to shop in February, and that left the nation’s retailers with another month of disappointing sales.

As storeowners reported their February results Thursday, Wal-Mart Stores Inc. announced sales at the low end of its expectations, and apparel retailers and department stores were again the hardest hit.

Consumers had no incentive to buy spring fashions like micro mini skirts in the frigid cold, analysts said.

But some retailers were exceptions, including Pacific Sunwear of California Inc. and Gap Inc., both of which reported that same-store sales — sales at stores open at least a year — beat Wall Street expectations. Same-store sales are considered the best gauge of a retailer’s health.

Overall, though, “this was a weak reading, and it is the same story line. But the only difference is that the weather complicated the issue,” said Michael Niemira, vice president of Bank of Tokyo-Mitsubishi Ltd. “Weather is a passing problem, but concern about war and the economy is a lingering issue and therein lies the problem.”

Bank of Tokyo-Mitsubishi’s same-store sales tally of 78 stores was up only 0.8 percent in February, compared with an increase of 6.2 percent a year ago, when unusually warm weather helped spur sales of spring clothes.

Niemira said it was the weakest performance since last November, when the index was unchanged.

The biggest blow in February came when a snowstorm blanketed the Northeast during Presidents Day weekend, forcing many stores to close and wiping out the much-anticipated sales bonanza needed to jump-start the spring season.

Niemira estimated the snow as well as cold weather and other storms in the Northeast and Midwest last month shaved about 1 to 1.5 percentage points on average from the monthly sales figures at national chains.

For example, Sears, Roebuck and Co., which announced disappointing sales, said it had to close 130 stores and key distribution centers during the long holiday weekend, wielding a “significant impact on sales.”
