The number of Americans seeking unemployment benefits fell 23,000 to a seasonally adjusted 393,000 last week. It was the second straight drop after Superstorm Sandy had driven applications much higher earlier this month.

A Labor Department analyst said Thursday that the storm had little effect on last week’s data. Applications had spiked to 451,000 three weeks ago after Sandy battered the East Coast, closing businesses in the Northeast and cutting off power to 8 million homes in 10 states.
