Very early but early signs certainly pointing to another recurve OTS

The 12z ECMWF has the same recurving scenario.

12z GFS not as bullish in 5 days, but later it has it stronger north of 30N.

Re: ATL: PHILIPPE - Models
What is the Euro doing no recurve dives under the ridge
Need to see confirmation on next run.

Not much left though and dives towards Hispaniola. Now if it's stronger and stays just offshore and heads west then it's an issue.
Ensembles are going to be interesting

Euro ens says the op is an outlier and has hardly any threatening members to the CONUS or any land for that matter through 360 from any TC. However, I still think a potential home brew via ridge over troubled waters setup part 2 (Ophelia was part 1) bears watching for the W Car, GOM, or SW Atlantic.

Uncertainty grows after that point, with the
track seemingly dependent on the intensity. A stronger system
would probably turn northward, like the GFS/HWRF/HMON models, while
a weaker one, like the UKMET/ECMWF solutions, would take a left
turn under the low-level subtropical ridge.

Re: ATL: PHILIPPE - Models
I would not call that "believing in Philippe", especially given that it does not take the storm to major hurricane status.

It does count when most intensity guidance and the NHC forecast don't even make this a hurricane.
