It is recurving at 300+ hours, where model accuracy is not good.

This. I believe many models showed Irma recurving way before FL this far out

12 EC has a low cutting off to its north and pulling it OTS. Still way too soon to determine if it's a random feature or not.

92L sneaks into very interesting position around the area of Puerto Rico. Then things get wonky with Florence sucking up everything in the basin with her as she exits the NE. Not so sure about all that.

I agree toad Iam not buying 92L being yanked NE on a dime. Lots of time to watch

Initially, it looked like the 00z GFS was going to be less ominous than the 18z, and that 92L would miss the islands, but I'm not so sure now. We'll see shortly.

At 174 it scrapes the Virgin Islands with 1007 pressure.

I finally see why it misses Florence's weakness. For about 30 hours (between hour 42-72), the GFS has it meandering around before moving west. Strange. Stranger even, the wave right behind it finds a way to gain latitude.

Looking at it in motion, I think that's 92L that then regenerates and heads toward Florida.
