I think it’s legit. It’s showing up strongly on ensembles. Timing is something that’s going to need to be sorted out.
I think we’re still on the edge of the window to increase TWO odds, so I wouldn’t expect anything yet. Though I agree that there are meaningful odds in that region. The signal looks real to me.
I don’t have the time to pull an analysis, but I think the GEFS has done an very good job overall identifying areas of tropical genesis, and has excelled against the EPS the last several years.
While it has a well documented western Caribbean genesis bias, it has done exceptionally well this season imo once we can identify what the genesis source is—i.e. a well established CAG or tropical wave. One area of diminished performance has been timing. It has generally been a little fast in forecasting genesis in CAG situations.
It looks like early November is a period to watch, especially if the upper level steering pattern looks anything close to what’s being depicted currently.
I guess going into winter mode will have to wait a few weeks for me , but I expected that a few months ago.
