Since this covers several storms and possibilities, I'm dropping this post here.

The 06Z GFS run is rather interesting today. The biggest attention getter is how it handles Leslie and Michael showing a large and fairly strong Leslie moving northward and eventually absorbing the much smaller and weaker Michael and becoming a rather massive and strong North Atlantic storm centered between Greenland and Labrador at the end of the forecast run. It also shows another Cape Verde storm developing and moving westward, but it hasn't really latched on to 90L as yet, or it simply doesn't develop it. The 00Z NGP does seem to want to develop 90L into a rather weak system and, eventually move it toward the central Gulf coast of Florida.
