The 2012 Atlantic hurricane season saw increased activity in its second half, with major storms including hurricanes Isaac, Leslie, and Michael. The season lagged behind previous years, facing a lull due to the reformation of El Niño, which potentially affected the development of tropical systems. Hurricane Sandy emerged as a significant storm, causing 66 deaths and economic losses totaling $2.577 billion.
