If you run the visible loop you'll see a massive outflow boundary to the NW.
That's always a terrible sign for tropical devlopment.
Agreed. This thing is not a TD ... yet. But new deep convection is firing near what you might call the "center" of the wave axis. And there is definitely potential over the next couple of days to see development.
I think what someone else posted earlier is appropriate -- this is very much like the storms of the past couple of years that came screaming into the E Carib., looked okay, but didn't really develop until they slowed down and got further W. We'll see.
