There is a tropical wave that is coming off the coast of Africa that is picked up by a couple of the latest models. Of course GFS is predicting development, I would expect that because of it's pre-mature nature. NGP is picking it up as well as ECMWF, these two aren't as fast on development at GFS.
Of course this is still way out there, but is worth keeping an eye on, as it could be the first long term development of the Atlantic season.
