I wonder how much these sorts of accounts are attributable to the beat of the Climate Doom drum combined with human recollection which is notoriously unreliable, malleable, and open to suggestion.
The US has just exited a period of a record setting "hurricane drought," so maybe the hurricane remnant weather seems unusual because no such storms have made landfall in the US for the past decade plus.
That this year had a cluster of large storms isn't really indicative of anything in and of itself. Most things appear to happen in clusters. Things aren't perfectly evenly distributed.
