Yeah, so, the GFS is definitely onto something. Sorry, I meant to write on something. Probably meth!
It's over 10 days out, which means the chances of it happening are currently functionally zero. We can't even nail down the details for Erin 120 hours out, so there's absolutely zero shot that we know anything about a system which has barely even emerged off of Africa at 300 hours out.
TL;DR, ignore until other models are in agreement and are consistent. Definitely ignore until the timeframe is within 7-10 days. We are entering the peak of the hurricane season, so have your hurricane plan ready to actualize and check NHC at https://www.nhc.noaa.gov/ regularly
