Sixteen days after the landfall of superstorm Sandy, much recovery work remains to be done. After Katrina in 2005, Sandy is the costliest hurricane to ever hit the United States, and New York and New Jersey have suffered most of the estimated $50 billion in damages. Most who lost power have had it restored by now, but many still remain without electricity or heat. Thousands of residents are still unable to return to their homes, and a lack of temporary shelter is making problems worse. More than two weeks after disaster struck, the long journey to full recovery has only just started. See also: Hurricane Sandy: After Landfall.
