Globally, 12-month running averages indicate nothing out of the ordinary, either for all hurricanes or major ones
The Atlantic hurricane season has now officially ended, so let’s check the numbers.
There have been six hurricanes in total, including three major ones, Dorian, Humberto and Lorenzo. Coincidentally both numbers are the same as the average since 1950.

There has only been one US landfalling hurricane this year, Dorian which clipped Cape Hatteras as a weak Cat 1.
