Tropical TD 9

This is a very touchy setup with this storm. Do not be surprised if there are still more shifts to come.

Yep... NHC 5pm

"The NHC track forecast at days 4-5 maintains a
consensus approach and shows a slower eastward motion, but future track adjustments are likely as confidence increases."
 
Euro firing warning shots about that kickback west at the end. 2nd run in a row
It’s a definite possibility if Humberto leaves it behind. I know someone was mentioning Dennis in 1999 that got left behind by a trough after moving parallel to the coast, sat southeast of Cape Hatteras for a few days before swing back west and landfalling near Myrtle Beach as a strong tropical storm
 
Is it actually a thing that the Hurricane models do a poor job initializing near by storms? If anything, I’d assume they do better with that compared to globals.
 
If it gets left behind, the Euro shows some pretty stout ridging building in over top, which would force it back west for a while. It's a plausible solution.

Maybe it stays so weak and disorganized that it doesn't get pulled away as much by Humberto and stays closer to the coast. No model really shows that, though. And conditions don't really favor it.

I don't trust the Euro or the GFS, outside of 72 hours, tbh. Both got an absolute beat-down with this one.

Hurricane season is turning into winter. Go with the model that shows least snow. And go with the model that shows no landfall.
 
TD 9 had hardly been moving. This slower than expected movement has increased the chance it will stay away from US:

From the 11PM NHC discussion:

It is
notable to point out the system has been moving slower than
anticipated over the last 12-24 hours, and this could have
significant implications on its ultimate track. Even in the first
48 hours of the track, there is quite a bit of spread in the
north-south direction in both the deterministic and ensemble model
guidance. Faster tracks appear to interact more with the upper-level
trough to the west, resulting in a track closer to the Carolina
coastline, while slower tracks largely miss a direct interaction
with this feature, and turn sharply east faster as Hurricane
Humberto approaches from the east, eroding the mid-level ridging
steering TD9 northward. Because it has been moving slower than
expected, its becoming more likely its ultimate track will fall in
the slower and sharper east camp. In response, the overall track
guidance this cycle shifted slower and further east, and the NHC
track forecast was shifted in that direction.
 
If this were a winter storm, it’d be time for one of the models to throw the weenies a bone and suck everyone back into paying attention. We will see
 
I was getting a bit confident until the end of NHC discussion....two important "ifs"....

"Even if this further offshore track pans out, the wind field is
expected to expand quite a bit, and given the expected storm
structure, a risk of significant heavy rainfall, storm surge, and
wind impacts is still possible for the southeast U.S. coast even if
the storm center remains offshore."

Sounds like they are saying regardless of whether or not this ever gets to landfall heavy rain and gusty wind is possible if not likely for central and eastern portions of both North and South Carolina. Along with Eastern Florida and Georgia

Would make sense you'd pack the gradient with that big high over NE and the storm to the south.
