2017 Atlantic Discussion Thread #2

I use both monosap (great for screenshots) and imgur

12z GFS also turns ^^^ that into Don.

Please forgive my ignorance. In this snip of GFS, would a storm follow along the edge of the brown area or would the yellow area mean it's open to pretty much go where it wants? Thank-you!

Thank-you!

In that map ju posted above, the pink, red and brown area in the Atlantic would be ridging, but that's at the surface in that chart. Weaker storms would tend to follow that steering. Stronger storms would follow deeper layer steering which is not noted in that graphic.

People are focused on 94L, but the ECMWF has been sniffing out a different Cape Verde system threatening the Lesser Antilles in 8-10 days. Don't look now, but the 18z GFS is hopping on board.
