Normally I'd dismiss these intensity runs, but they forecast Danny to become a Cat 3 and nobody believed them, but it did, so they may warrant a closer look now if they continue for multiple runs.

The 12Z ECMWF really likes this system:

So does the 12Z UKMET (132 hours):

Out through 192 hours and 00z GFS looks ready to blow up 98l and recurve it into a weakness east of the Bahamas.

but its a close call on the 0zGFS of a ridge bridge which needs to be watched as this may have better conditions than Danny and could be a strong hurricane in the Bahamas

Looks like it could be left behind

on the 0zGFS it seems to leave 98L behind near the Bahamas which is something that needs to be watched in the SEUS past 8 days

True, and it's likely a strong Cat 3 by then. 950mb at 240 hours.

00z Euro still likes it and blows it up into a major in the vicinity of the Bahamas very similar to the 00z GFS. So there seems to be good consensus at the moment from these two global models at least.

Looks like a fish on this run, but it has trended west some of the 12z Euro so worth watching.

Interest in the Lesser Antilles and maybe Bermuda the East coast will have to keep an eye on this as we head to next week if the Euro is even close to right

For now the Euro is recurving a powerful system far enough east of the U.S. that it's not going to get a lot of discussion. But all it takes is a shift or two more to the west and this thread (media, JB tweets, etc) would be going crazy.

06z GFS backs off, let's see if the 12z runs of the GFS/Euro follow suite.
