NOAA’s updated hurricane season outlook in August called for 12 to 17 named storms, including 5 to 8 hurricanes, with 2 to 4 of those predicted to become major hurricanes.

Five named storms made landfall in the United States during 2016, the most since 2008 when six storms struck. Tropical Storm "Bonnie" and Hurricane "Matthew" struck South Carolina. Tropical Storms "Colin" and "Julia", as well as Hurricane "Hermine", made landfall in Florida. Hermine was the first hurricane to make landfall in Florida since Wilma in 2005.

Several Atlantic storms made landfall outside of the United States during 2016: Tropical Storm "Danielle" in Mexico, Hurricane "Earl" in Belize, Hurricane "Matthew" in Haiti, Cuba, and the Bahamas, and Hurricane "Otto" in Nicaragua.

The strongest and longest-lived storm of the season was Matthew, which reached maximum sustained surface winds of 257 km/h (160 mph) and lasted as a major hurricane for eight days from September 30 to October 7. Matthew was the first category 5 hurricane in the Atlantic basin since Felix in 2007.

Matthew intensified into a major hurricane on September 30 over the Caribbean Sea, making it the first major hurricane in that region since Poloma in 2008. It made landfall as a category 4 major hurricane in Haiti, Cuba and the Bahamas, causing extensive damage and loss of life. It then made landfall on October 8 as a category 1 hurricane in the U.S. near McClellanville, South Carolina.

Matthew caused storm surge and beach erosion from Florida through North Carolina, and produced more than 254 mm (10 inches) of rain resulting in extensive freshwater flooding over much of the eastern Carolinas. The storm was responsible for the greatest U.S. loss of life due to inland flooding from a tropical system since torrential rains from Hurricane Floyd caused widespread and historic flooding in eastern North Carolina in 1999.

“The strength of Hurricane Matthew, as well as the increased number of U.S. landfalling storms this season, were linked to large areas of exceptionally weak vertical wind shear that resulted from a persistent ridge of high pressure in the middle and upper atmosphere over Caribbean Sea and the western Atlantic Ocean,” said Gerry Bell, Ph.D., lead seasonal hurricane forecaster at NOAA’s Climate Prediction Center. “These conditions, along with very warm Caribbean waters, helped fuel Matthew’s rapid strengthening.”
