Do I hear 20?

There it is, looming off the eastern coast of the Yucutan penninsula. TD 20 came while I was busy learning more PET stuff. So which one becomes Stan first, 19 or 20. 19 is still heading into the mid-Atlantic, and 20 looks to be heading across the Gulf into central Mexico. NHC forecasts call for TD 19 not developing into much, but TD 20 might get stronger once it gets into the Gulf. Which one becomes Stan, and which one becomes Wilma? Anybody want to put a pool together?
