As the 2016 Atlantic hurricane season officially draws to a close just days after Hurricane Otto became the latest calendar year Atlantic hurricane on record to make landfall, the question on everyone’s lips is: are the seasons growing longer?
For if Otto, which struck southern Nicaragua as a Category 2 over Thanksgiving, is the last hurricane of the 2016 season, it will mark the end to the longest hurricane season on record the Atlantic Ocean has seen, according to NOAA.
The 2016 season had an early beginning—well ahead of its June 1 official start—when Hurricane Alex became the first Atlantic hurricane in January since Hurricane Alice in 1955.
At 75 knots, Alex was also the second strongest Atlantic hurricane on record in January, after 1955’s Alice at 80 knots, according to the 2016 season summary by Phil Klotzbach, head of Colorado State University’s Tropical Meteorology Project.
Regardless of whether this points to any long-term trend, it does appear that residents in hurricane-prone areas should keep an eye on the tropics year-round, not just in the June 1-November 30 window.
In the end, the 2016 Atlantic hurricane season was somewhat above average. As CSU’s summary outlines:
“The season was characterized by somewhat above-average named storms and major hurricanes, with slightly above-average hurricane numbers.”
The final tally was 15 named storms, including seven hurricanes, of which three were major hurricanes.
Three tropical storms (Bonnie, Colin and Julia) and two hurricanes (Hermine and Matthew) made U.S. landfall this year, according to NOAA.
There were a number of key takeaways, according to CSU, not least that a total of 78.25 named storm days and 26.25 hurricane days occurred in 2016—the most in an individual Atlantic hurricane season since 2012.
The 9.75 major hurricane days that occurred in 2016 are also the most in a single Atlantic hurricane season since 2010.
Florida’s record-long hurricane drought at 3,966 days ended when Hermine made landfall in the Big Bend of Florida on September 2.
Meanwhile, Matthew became the first Category 5 hurricane in the Atlantic basin since Felix (2007).
No major hurricanes made United States landfall in 2016, although Hurricane Matthew came within about 50 miles of breaking this streak, CSU notes:
“The last major hurricane to make U.S. landfall was Wilma (2005), so the U.S. has now gone 11 years without a major hurricane landfall. The U.S. has never had another 11-year period without a major hurricane landfall since records began in 1851.”
