Thank you Sandy for the graphic that shows all of what is moat.Very interesting stuff there for all to learn.

[Derek Ortt]

I dont see a moat on the 2145 or the visible

that is very hard to see though on conventional imagery. We need microwave to see that clearly

57,what is a moat?

I'm not wxman57 but i remember seeing this on a page i found

The term "moat" usually refers to the region between the eyewall and an outer rainband, such as a secondary eyewall rainband (see the image above). The moat is the relatively light rain region between the rainband and the eyewall.

57,what is a moat?

I posted a link to this MIMIC imagery a few days ago and thought it worthwhile to post again given the ERC conversation here.. It shows Ivan going through an ERC for those who wnat to know more. You'll see a secondary eyewall form, along with a moat (a ring caused by subsidence that forms between the inner and outer eyewalls). Then you'll see the inner eyewall collapse and the outer eyewall contract to take its place.

Right now, it looks like it's back at peak strength IMO. The eye is really good now (like 50 hours ago). The convection isn't weak enough to sound the EWRC bell yet in that region.

WOW - What an amazing storm to track!!!!!

Also - what an amazing board to learn about TCs - I'm as impressed by the 160+ pages of discussion (to date) on this storm as I am by the storm itself - THANK YOU TO ALL!

A good indication of direction is to watch the direction of the clouds blowing off. Notice that the clouds being vented are being pulled north. She's (forgot the terminology--what Isabel was) on the south side and 'top heavy' on the northside.

Constant for the last hour and a half.

[weatherguru18]

Can somebody help me out with terminology? I can't think of what a hurricane is called when there isn't very many clouds being vented off. Very clean cut so to speak. The only hurricane I can think of is Isabel...it was Isabel right? It's going to drive me crazy!

[HURAKAN]

You mean, annular?

[weatherguru18]

You mean, annular?

YES!!! THANK YOU!!!!

[KWT]

I think NHC will probably upgrade to category-3, its close enough now to warrant it being upgraded IMO. Also still looks pretty good though I'd imagine it must be getting close to her peak right now given the heat content in the region.

gotoman38, yep for all these long trackers you tend to find these threads get close to if not above 100 pages long, esp when there is a threat to the USA.

[srainhoutx]

Great job folks. Sure looks good from a distance, doesn't it.
