One of the big reasons for GFS caving to the ECMWF somewhat on the track of now #TD9 is showing this upper low to the NW of the storm. Will likely cause a sharper turn towards Cuba. How sharp though is still very much up in the air and will help determine the final track. https://t.co/GSV9wFG1ln pic.twitter.com/SD2BmoknrG
