in 2016 was above the long-term averages of 12 and 6, respectively.
The season total of major hurricanes matched the long-term average
of 3.

In terms of Accumulated Cyclone Energy (ACE), which measures the
combined strength and duration of tropical storms and hurricanes,
activity in the basin for 2016 was above normal. Overall, the ACE
for the season was about 40 percent above the 1981-2010 median
value. It is noteworthy that just three cyclones, Matthew, Gaston,
and Nicole, produced more than 70 percent of the seasonal ACE, while
many of this year's other cyclones were relatively weak and/or short
