Re: Hurricane Bertha in Western Atlantic
Bertha appears to be taking on more annular characteristics. Anybody else think so?

Yeah that may well be the case, I've see recon before show these double eyewalls where the inner eyewall just won't collapse!
Hurakan, I'm not sure though I bet this may have a shot at the longest lasting July tropical cyclone in the north Atlantic. Emily tracked a long way as have a few others but this has the advantage of forming a good deal east of most of those.

I thought that earlier, but didn't post it, partly because people tend to get angsty about anyone mentioning annular hurricanes.

The following is the opinion of Cryomaniac, and is not backed by any evidence, meteorological, economic or otherwise. As such it should not be used for any purpose.
I seriously doubt it. I refuse to say it's impossible, because it isn't.

Re: Hurricane Bertha in Western Atlantic
The divergence from the upper low is providing excellent ascent and outflow along the western semicircle.
On another note, the outer (secondary) eyewall is steadily contracting, while a larger eye develops simultaneously and shrinks as well.

Re: Hurricane Bertha in Western Atlantic
looks ok but last image shows holes in convection
you gotta think about upwelling over the next couple days (should model speed verify) this would inhibit her abit...ya
also appears northward motion may have taken a breather (but would need a few more images to confirm)

That's, again, wrong. Operationally it's 13.5475; best-track is 13.4125. Not 13.915.
