Morning All.

Could someone explain the difference
between the


and the official

NHC track?


OFCINHC official forecast (Interpolated 06 hours)

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


I suspect the difference is a result of the times corresponding to the NHC forecast plots. The Evans OFCI plot is marked 0600 UTC, the NHC track you reference was 3 hours later at 0900 UTC or Z. The 0900 UTC plot probably reflects and update from the previous one shown in the Evans image.
