:6z GFS does not develop 99L. No euro ensembles get into the Gulf, the Icon is weaker, and a the few GFS ensembles that get into the gulf stall it out somewhere in the Gulf. Just not a lot of support for 99L. Conditions are pretty hostile for it at the moment, recon goes out there tonight, so hopefully it'll help with 99L. It's tenacious, but there is still no low level circulation to speak of. But right now I'd say this isn't going to do much more than rain a lot in the Yucatan Peninsula when it gets over there. Setup just isn't right for much more than that. Still late August so it's something to watch, but odds are enough to say there's nothing overly concerning at the moment. That doesn't mean quit watching it, just that the odds are stacked against it right now.

It's moving too fast this morning to really get the LLC going, so I don't expect much. Something to watch down the road, but this pattern typically puts the waves into Central America, hurricane Michael was a notable exception to that idea, another was Dolly in 2008, so there is precedent, but it's still very unlikely. Barbados and the islands will get gusy wind and rain today/tomorrow though.

Since 99L is starting to enter radar range I added two radar records of it https://flhurricane.com/cyclone/animationlist.php
