Re: andrea heading out

Well, yeah. Overnight and this morning Andrea has reconstituted herself such that IMHO just about any sceptic should now be not only accepting, but embracing of her status as a named storm, and yet, based on the most recent STDS, I can only conclude that NHC has decided to let this one ride out until the post-season, because Andrea overnight and early this morning is looking virtually 100% nameable material.

Lacking any reporting buoys or cman stations in her area at all, and only having a few ships that one could argue are probably trying to avoid her at this point, the apparent decision not to send in recon - again- while understandable, given that she is heading
away from the U.S., is most regrettable. Interests in and close to Bermuda would be wise to treat her as if she was actually a named storm.

Overnight and this morning deeper convection wrapped all the way around the cyclone. Certainly there have been a few breaks in the continuity, and still some more flareups and flaredowns, but overall the structure has been solid, with the llc nuzzled just about to the right of middle at all times. Even a dimple appeared a few times where a budding eye would eventually try to form in a system with greater chances to grow. Inflow from the south has been nothing but healthy, and there have even been a few outflow channels set up for her, in the SW, NE and SE quads.

The convection doesn't resemble that of a mid-August hurricane traveling through the Gulf of Mexico, because this is most certainly not mid-August and the water temps out where she has been are at least 5c lower than the comparable mid-season example down in the GOM. All the more reason some may want to argue that she is still more subtropical than tropical. I'm still OK with that, I guess. I guess I would say that the far more analogous recent examples at this point would be the late-season northern latitude systems of 2005, than of some early season subtropical disturbance.

It will be interesting to see how she interacts with or responds to the front laying very close to being on top of her now, going forward. That ULL to her west and the front to her north so far have served to create a bit of an outflow opportunity. Merging with the front seems entirely plausible. Would seem less likely but possible for her to be nudged south of it and stay a bit further south, never to merge.
