NEW YORK/DETROIT (Reuters) - Hurricane Irene hit the U.S. East Coast at the most inopportune time for many businesses, keeping millions of shoppers away from stores and auto dealerships during what should have been a busy weekend.
Irene struck a wide area from North Carolina to Vermont, inflicting damage on the August sales results that automakers and many big U.S. retailers are set to report later this week.
The weight of low consumer confidence, the stock market and low inventories of Toyota Motor Corp (7203.T) and Honda Motor Co (7267.T) vehicles are the key reasons auto analysts expect U.S. new vehicle sales to fall in August from July or be flat at best.
Still, analysts predict a 5.2 percent increase from August 2010, though that tally was made before the weekend's storm shut many East Coast auto dealerships.
"What's concerning to us is a huge percentage of sales come in the last weekend or the last week of the month so it hit at that really crucial time," said Edmunds.com analyst Michelle Krebs. "The good news is that sales are better than May and June."
The storm also forced stores including Macy's Inc (M.N) and TJ Maxx in New York to close over the weekend, a period when people are more likely to be shopping.
A tally issued by Thomson Reuters on Monday found that analysts expect the 25 retailers in its index -- including Costco Wholesale Corp (COST.O), Target Corp (TGT.N), J.C. Penney Co Inc (JCP.N) and Saks Inc SKS.N -- to report a 4.7 percent increase in August sales at stores open at least a year, a measure known as same-store sales.
The chains that report monthly sales represent only about 10 percent of retailers, and the storm affected roughly 15 percent of the U.S. population, said Craig Johnson, president of Customer Growth Partners, who lost power at his Connecticut home early on Sunday.
"There will be a few retailers that will use the hurricane as an excuse for poor performance, but these are some of the same people who have been performing poorly for months now," he said. "Gap's numbers are going to be lousy this month, Aeropostale's will not be good, but they were bad before the storm."
As much as a fifth of U.S. auto sales are often generated in the states that were affected by Irene, said Paul Taylor, chief economist with the National Automobile Dealers Association. In those states, August sales will likely be down about 10 percent.
A bigger problem related to Irene may affect September sales as well, Taylor said.
"The real issue is going to be flooding," he said.
The average forecast of 44 economists surveyed by Reuters was 12.1 million vehicles were sold on an annualized basis, up from 11.5 million a year ago, but off slightly from 12.2 million in July.
Honda appears to be struggling the most. Edmunds.com and TrueCar.com expect Honda's sales for August to drop by 22 to 25 percent from last August, and for Toyota's sales to fall 11 percent to 14 percent.
They show General Motors Co's (GM.N) August sales up 20 percent, Ford Motor Co (F.N) up 12 to 14 percent, Chrysler Group LLC up 21 to 22 percent and Nissan Motor Co (7201.T) up 16 to 22 percent. Chrysler is under the management of Italy's Fiat SpA. FIA.MI
Jim Ziegler, a dealer consultant who spoke with dozens of dealers on Monday, said August auto sales figures will "definitely take a hit" due to Irene.
Due to power outages and flooding, Ziegler said, customers are not expected to return in big numbers until the upcoming Labor Day weekend in early September.
Still, auto dealers are happy the storm was not as damaging as some had expected.
"Almost everybody has the feeling that they dodged a bullet," Ziegler said.
Retailers that sell back-to-school items likely felt Irene's pinch as the storm essentially shut down malls on a weekend when parents normally shop for clothes and notebooks, not bottled water and flashlights.
"This is a major weekend of sales that were planned, but that won't happen, in one of the most densely populated regions," said Joel Bines, a managing director of consulting firm AlixPartners.
The damage could take 1 percentage point off August same-store sales, said Bines, adding that leftover merchandise will likely be discounted, damaging gross margins.
Department stores including Penney and Macy's and such clothing chains as Gap Inc (GPS.N) and Aeropostale Inc ARO.N are seen as most exposed to a slowdown.
Most retailers' monthly reporting periods ended on Saturday, meaning the pain of Sunday's missed sales will carry over into September's tally. Chains that report monthly sales and are heavily exposed to the East Coast include BJ's Wholesale Club Inc BJ.N and TJX Cos Inc (TJX.N).
However, those chains as well as others such as Wal-Mart Stores Inc (WMT.N), do not report monthly sales.
A large portion of back-to-school sales, retailers' second-most important season after the winter holidays, could be lost for good, especially if it takes time for the transportation infrastructure to get back in place.
"There are millions of dollars in economic activity and productivity that were lost and simply will not and cannot be recouped," said weather tracking firm Planalytics.
