Highest ACE seasons 3-6 are so absurdly close (separated by <5 ACE!) that another relatively long lived major or two longer lived moderate hurricanes after Ophelia would quickly vault 2017 from 7th to 3rd all-time. Maybe a little bit of a stretch at this point, but with storms like Mitch, Lenny, Michelle, Sandy, Paloma, etc. on the books in this active era, it's not implausible that we could add enough after Ophelia to reach 3rd all-time.
...but still, though, a lot more interesting than the 2013 season.
Not a meteorologist, in fact more of an idiot than anything. You should probably check with the NHC or a local NWS office for official information.
