On October 29, 2012, New York and New Jersey were inundated by Hurricane Sandy. Its 14-foot-high storm surge, a local record, caused massive street flooding in many parts of Lower Manhattan. Power to the area was knocked out by a transformer explosion at a Con Edison plant. With mass transit in New York City already suspended as a precaution even before the storm hit, the New York Stock Exchange and other financial exchanges were closed for two days, re-opening on October 31.
