The reliable EURO takes it into the Caribbean, an Ivan track, but yesterday it had it north of the islands, so until we get a consistent pattern, I'm not buying into anything yet. What's happening with 90L is simple. The disturbance was connected with a wave that was just identified by the NHC last night, though some already knew it was a wave. The split between the wave and the disturbance (90L), is causing the convection to elongate and dissipate, now the new wave off of Africa should merge with 90L and create a new feature, but still probably called 90L. The track is unknown, but I find it highly likely the ridge holds and steers whatever forms, if it forms westward. Can't give an idea of exactly where it will go, it's too early, but the trend on the models and steering favors a westward to northwestward motion for the next 5 days, a slow progress at that. People from Maine down to the GOM coastline should just eye this for now until or IF something forms out of this mess.
