I hate to throw a snag in the forecast. But the new 00Z GFDL and BAM Suite take the storm back west toward MS/ LA.

Granted the SHIP and DSHIP are at Tropical Depression wind speeds. It would still take Debby 120 hours or 5 days to reach those forecast points.

I'm still looking at the new guidance. Will update as necessary.

Looking at the 18Z GFDL and HWRF they are now considered old.

GFDL makes an initial landfall at the Mouth of the Mississippi River and then bounces over to a second landfall near Gulfport,MS at 992mb.

HWRF makes a single landfall near Orange Beach,AL or the eastern side of Mobile Bay.
