It’s official. The 2016 Atlantic hurricane season wraps up Wednesday with 15 named storms, 7 hurricanes and 3 major hurricanes. It is the busiest Atlantic season since 2012. On average there are 12 named storms, 6 hurricanes and 3 major hurricanes, so there was an above average number of named storms and hurricanes in 2016. The slightly above average season is in line with predictions from NOAA and Colorado State University. In their late summer update NOAA upped their forecast to 12-17 named storms, 5-8 hurricanes and 2-4 major hurricanes. Colorado State anticipated 15 named storms, 6 hurricanes and 2 major hurricanes. Prior to the start of the 2016 season La Niña conditions were anticipated at the peak of season late in the summer. With possible lower wind shear and warmer waters tropical cyclone development would be enhanced. This never panned out and the La Niña Watch was dropped in early September. Even without the presence of a weak La Niña a slightly above average Atlantic season occurred.Several storms were strong and long-lived in 2016. When we analyze the total energy output of all tropical systems during the entire hurricane season, or ACE, the number is high is 2016. According to Dr. Klotzbach at Colorado State University the ACE this year is 134. This is more than double the ACE from 2015. Two hurricanes made landfall in the U.S.. Hermine is the first hurricane to hit Florida since Wilma in 2005. Hurricane Matthew paralleled Florida and Georgia and made landfall in South Carolina as a category 1 hurricane. Matthew was a category 5 hurricane in the Caribbean. It is the first category 5 hurricane in the Atlantic Basin since Felix in 2007. Tropical Storm Colin made landfall in Florida and Bonnie struck South Carolina as a tropical depression in South Carolina. Julia threw a curve ball.
