So Far no consistent west winds. I don't think the low can be considered closed off at the surface. Mind you, I think it's only a matter of time before it does, and they may find more west winds in there before they leave. but for now, I'd consider it a very very sharp wave.

Edit -

And just as I say this, they find a group of west winds of Tropical Storm force. However those winds still appear to be away from the center, so it's not a terribly organized at this point. But I think it's good enough to call and probably call as a Tropical Storm off the bat.
