Hurricane Gaston

Jo's written a blog about Gaston and some of the media stories over the weekend:

What's all this about Hurricane Gaston?

Is it just me or is Gaston taking on an annular form?

The large eye is hard to miss, but banding features still seem evident in the earlier stages of this loop. Near the end, though, they seem to dissipate.

Annular storms tend to persist more when crossing SSTs below 26*C but Gaston may well venture too close to the Atlantic troughs before that becomes much of a factor. It'd have to track further S and E for the annular nature to really make a difference - assuming, that is, that it's achieved that form in the first place.

Gaston has strengthened again to 120mph. NHC calling it's satellite presentation outstanding (big eye, symmetrical ring of convection).

I agree with Singularity that were this further south it would probably have gone annular.

Is it just my memory or is it very unusual to see such a big 'eye' in an Atlantic hurricane. The models did well as some of them were showing annular type on the simulated infra-red projection over a week ago.

Gaston lasted 12 days but is now dead.
