This morning’s Eyewall post by @Matt has a bit more detail:
We continue to see some “noise” from the usual suspects (cough, the GFS model) far out in time in the Gulf or western Caribbean. This is a normal model bias for late September and October, so get used to seeing spurious tropical systems on that specific model guidance.
That said, there is some very, very modest support for some potential “noise” in that area on other guidance. We can’t latch onto a specific disturbance right now, nor can we say something will come of this with any confidence whatsoever. But the reality is that it’s the time of year we watch there, and the models are producing noise there to a small extent. In other words, we’ll be looking there to see if anything can emerge to close September or start October. For now, no one need be worried at all.
