It's way to early to make any predictions about this baby. There is a good deal of uncertainty surrounding this storm. It has a 20% chance of development in the next two days. However, having no center of circulation, position estimates are problematic. If you can't get an accurate center position, then you can't get an accurate track estimate.
With this storm developing so close, it could surprise us. However, the good thing is with it developing so close, it should not be able to experience excessive growth.
Every time I say something about a small storm, I think of 1985 Hurricane Juan that took everything I had.
