Lane will likely be in the history book of hurricane names; looks almost certain to be retired.

Re: 2018 EPAC Season
18z GFS finally turns the 10/50 into a potent system after being so so for days. Develops more behind it, another outburst is in the works. NHC may need to bring out the colors again. As has been the past month, anything that wants to spin up seemingly has been doing so.

Re: 2018 EPAC Season
The EPAC squad on Storm2k has grown with Hector and Lane, and I think we set a record for an EPAC/CPAC storm with 100+ pages.
Looks like we're in for a busy September with more long trackers.

Re: 2018 EPAC Season
The current season is the season of intense long-tracking hurricanes. Best season I've tracked so far, surpassing 2015. Correct me if I'm wrong, but 2018 is the first season in the 21st century to have at least two hurricanes with ACE above 40 each. Miriam (and other storms) could follow Hector and Lane. I also expect and hope for a system similar to Ioke crossing the West Pacific and racking up heaps of ACE, except for the Johnston Atoll impact. High ACE long trackers that avoid land are my favorite.
2018 is on its way to becoming a hyperactive season. Perhaps it could be the first >200 season since 2015, and the second in the century. The streak would have continued if it weren't for 2017.

Getting to 200 isn't difficult given where things are. A long tracker, and a few typical eastern basin systems Sept/Oct/Nov can easily do it. So if we just follow climo it's there. Now to get within striking distance of 1992/2015 we'll need two long trackers similar to that of Lane/Hector and a bunch of shorter ACE systems. Or we can pull it off like 2015 and a whole bunch of Cat 4s in the eastern basin the rest of the way.

Re: 2018 EPAC Season
Something to note. I know Yellow Evan touched based with this but the longer range guidance has had northerly bias with west tracking systems. Miriam to be, like Lane and Hector, what looked like a safe east recurve is now progged further south on the guidance. Sitting near the same spots the predecessors were. Sprawling 500mb north Pacific ridge.
Hawaii could be staring at another system nearby
