Per the 0Z GFS, Grace slowly gets stronger through Tue while shear is under 10 knots, but then it weakens when shear rises to the 10-15 knots range (which doesn't really seem all that high) while approaching 50W.
Edit: This is headed toward the Leewards/VI/PR as a weak TC.
Look at the bright side. People like Luis on PR could benefit from a weak but wet Grace.
Edit: As it reaches the Leewards, shear increases to near 20-25 knots, which is consistent with earlier GFS runs. Thus Grace further weakens.
Beneficial rains into the VI's and PR. Yay if this were to end up verifying!
This run is a bit south of the last three GFS runs with the vorticity moving just S of PR.
