You’re right about a lot needing to go right for 20+. I think the trend the last few years and the extraordinary base state of the basin this season would have me shocked if it didn’t happen. Of course, we know a fair number of NS end up debatable anyway.
It’s the H and MH numbers for me. The key question IMO is whether an active WAM causes a feedback of strong SAL bursts that reduce instability in the tropical Atlantic. If not, I think we threaten records. Even if it does, I’d be surprised if this isn’t a top 10 season for activity.
