I think 91 is far from a tropical depression but defintely a tropical disturbance. It may have a center, it may have two... even the models don't seem to start it out at the same starting gate. As it gets closer the recon will go in and see what is what.. for now, it's on wave watch..

Gulf... 50/50 maybe... something is there.

But...at peak of the season, we have no coordinates being issued. Go figure on that one.
down the road we might have big trouble with 91 as most models show a high digging in and pushing it west towards land ...and yet.. have seen some forecasted plots that keep it low

Going to be an interesting one to track for NHC if it develops. And, it's big so size makes a difference in storms and what they are capable of doing, etc..
