More 12Z runs:

The models have switched in some cases. The GFS/CMC moved W to just SE of Bermuda whereas the Euro moved E to well E of Bermuda.

Icon: still well to the SW of others with it much weaker SSW of Bermuda then recurving NW

JMA: TS at Bermuda at 192

18z gfs is closer to bermuda, 18z icon shifted right and aligns pretty closely with the 18z GFS out to the end of the icon's run.

Check this out folks: 0Z GFS is much weaker with strongest at 1005 mb/barely a TS followed by it weakening and then dissipating over open water of the SW Atlantic into nothing! The prior 13 runs all had hurricanes, usually MH! What the?

Would be a bad look for the models if this also vastly underperforms. Great news for real life impacts though.
