1 thing to remember.
The accurate tracking of how many storms happen per year was not really possible until weather satellites became available.
Prior to that many of the storms we now watch on the news that spin in the open ocean, never touching land, would have never been counted. In the past the best you could do is count on harbor reports tracking high surf conditions or ships at sea reporting storm conditions to track a storm at sea.
Hurricane numbers from just 50 years ago, prior to hurricane tracking by planes, fall into that group so making comparisons to todays numbers is not really honest.
Just watching the evening news you can see that in some years fully a third of all storms named and counted never see land. Their existence would not have been known except for planes and satellites.
