For the North Atlantic...Caribbean Sea and the Gulf of Mexico:

One named storm, Otto, which became a hurricane, formed in the Atlantic basin in November. Based on a 30-year (1981-2010) climatology, a named storm forms in the basin in November in about 7 out of 10 years, with a hurricane forming about once every other year.

For the 2016 season, 15 named storms formed, of which 7 became hurricanes, and 3 became major hurricanes. One unnamed depression also formed in the basin. The number of named storms and hurricanes 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 lived.

Reports on individual cyclones, when completed, are available at the National Hurricane Center website at www.nhc.noaa.gov/data/tcr/index.php?season=2016&basin=atl .
