12z GFS is still struggling with the system, as the satellite shows a circulation forming, sheared north to south, which could push "formation" further south. It could disperse over the everglades too and nothing will form, so it's a bit of a mixed bag.

Global models like the GFS/Euro tend to do their worst with weak, sheared systems. The lack of GFS support makes it difficult to launch an invest, so it's still not a guarantee we'll get an invest for a while. (most of the hurricane models use the GFS as a base)
