A lot going on in the upper atmosphere around this

Seeing a lot of PV streamers around this.

They are high up at 360K potential temp.

When this happens, kinks and vorticites form that could work their way down to the surface.

This could aid in genesis.

In fact, this kind of structure happens often in late-season development.

In some cases, mild shear can actually help development.

Looks like spin up will be in about 48 to 60 hrs.
