South Atlantic?

So they say there's a low potential for development down there. I suppose it's based off the storm moving east-northeastward offshore Uruguay. It's probably too far south, and unlike Catarina, Arani, and Anita, the storm is moving quickly (the others all stalled or moved westward at some point). Is there any model interest?

This is just my personal opinion, I don't think there is a chance at all of this becoming an organized system. I think since it is in the Southern Hemisphere and moving towards Africa, this would be a first in history if it did. I could actually seeing it forming a rotation but rotating the opposite direction than what we are used to, if somehow it does form and some how gets in a pattern where it could turn around and start heading West once near the Equator then who knows. But I really think the likely hood of anything come out of this system is from -100% to .000001%.

Too far south. Too much shear.

Yep, it's gone from the potential development map.

here is where i get to show off my ignorance :) If a storm is spinning in the southern hemisphere, does it really spin in the opposite direction?....and if it does, what would happen if a fully developed storm crossed the equator and into the northern hemisphere?

a storm in the southern hemisphere does spin the other direction.

It would be very hard for a system to cross the equator. There is only one system that crossed as a disturbance, that was Agni in 2004. The vorticity was nearly all caused by the monsoon circulation as the Coriolis is so small at the equator. It spun counter clockwise
