Could this be true? In 2007 IPCC predicted fewer but more powerful hurricanes but now the jet stream weakness allows more to start. I suppose the next few years will tell - or climate science a bit beyond me.
fwiw

2005-2016 126.58 17.33 9.50 4.67
If anything the numbers seem to be higher after 2005. Note that inclusion or exclusion of a single year (such as 2005) can have quite a large effect on the numbers.
