Strong Tropical Wave emerging from West Africa (Is INVEST 90L)

I think is time to have a thread for the wave that will emerge Africa in a few days as the models are bullish on it.

Animation updates every 3 hours.

Yep right there in Senegal. I also see a possibility that the yellow comes out for this at 2. The thing to watch is how this does around 7 to 8 days going through the tutt.

This wave at 25w looks impressive today. Nice spin and a lot of convection.

What kind of paths are they showing? Hopefully not FL because some areas of the Keys are just now cleaning up the canals, almost a year after Irma.

Coming into Western Caribbean view heading WNW in the long-range. Also looks to be organizing and not weakening like the GFS shows:

Well, it is a long ways out. Lots can change in that time frame. I remember a few days ago when the models started showing these as recurves asking that question because people were talking about the ridge in place then. It looked like the models showed the ridge retreating to the Northeast, allowing for the systems to recurve. Seems fishy (pun intended).

I think NHC is waiting for all models to agree that development is in the 5 day window. I'm expecting a mention tomorrow if models continue to show development.
