Morning All.

Could someone explain the difference
between the
OFCI
here:

and the official

NHC track?

OFCINHC official forecast (Interpolated 06 hours)

Because NHC has Gulf Shores Landfall and OFCI has Pearl River.

Thanx.

Looks to me from the last pass that the FL center and the 850 center are now stacked and at about 15.4 / 70.1. That apparent NW motion in the vortex fixes will also stop. That was the FL center catching up to the sfc center. They should now start moving 285 or so. Now that they are stacked...hold on to your seatbeats. OK...going fishing.

Shurikan: In any event, the mean vector of the convective blob has been moving steadily almost due west since east of the islands; and, given Isaac's behavior so far, I'm inclined to doubt any asserted movement otherwise until I actually see the convection trend in that direction as well.
