ATL: IGOR - Ex Hurricane - Discussion

[Just Joshing You]

The last image shows a pentagram inside Igors eye. Where can I find a 1km sat view?

12z euro ....major shift W

144 hr position 34.5/ 69.5.....then out to sea hour 168

noses north central atlantic high SW late thur nite out ahead of igor....and keeps it there for a couple days

[brunota2003]

You still need 7.0...the Dvorak charts don't break down into anything less than .5, and 6.5 is 146 mph...or Cat 4.

If Igor continues at this pace he may get trapped by Friday.
Needs to pickup speed to catch the weakness.

From IR views the trough doesn't look all that strong.

I am talking about UW-CIMSS ADT which goes to every single point.

I thought that I had seen real-time high-res images from GOES-15, but I can't find the link...

[brunota2003]

In that case, yes it would be 6.8 or 6.9, but they wouldn't upgrade most likely unless there were 7.0s across the board...or one read above 7.0.

There's NASA GHCC: http://www.ghcc.msfc.nasa.gov/GOES/

This is the best that I could grab from that site:


edit: Playing with the custom animation feature you can see a lot of detail in the eye and the eyewall.

hmm....Usually vorticies are seen in intensifying systems and in Cat 5's.

Not necessarily, at least not that I've heard. Sure, you usually see them in more intense hurricanes, but I'm not aware of any dynamical dependence on strengthening or on reaching Cat 5 status for them to appear; they have more to do with the internal dynamics of vortices (the ratio of inflow wind to rotational wind -- something known as the swirl ratio) than on the strength of the vortex. It just so happens with hurricanes that they tend to be most obvious in strong hurricanes, but I wouldn't be surprised if they showed up to some extent in lesser storms as well.

Interesting. I try to watch for warning signs (ERC, intensification, decreases in intensification), and just about every time there has been a quickly intensifying system Cat 2 or 3+, it has these vorts. As we have seen in the last few hours, intensification has occured.

[hurricaneCW]

I wonder if his very slow movement could have a huge implication in the track. The latest gfs has also shifted a bit further to the west. If the track ends up being 100 miles to the west of Bermuda, then that's pretty good because it would be right in between the east coast and Bermuda.

Igor has really ramped up once again, he could make another run at Cat 5 today. Also, the size has really expanded as well, I'll bet tropical storm force winds are well over 200 miles out now.

[aerology]

Every 25 hours these tropical storms have a surge of growth as the moon passes overhead, with a more general increase in size 12.5 hours either side when the secondary bulge in the atmosphere passes through their area, this and the angle the moon and sun are off from directly overhead gives us all of the wobbles to watch.

Any wallpaper sized pictures of Igor from space?

Great view. Thoughts anyone?

Igor's eye from this 8MB image

[Aric Dunn]

Look at that eye contract... either there it is intensifying more or the inner eyewall is contracting while and outer eyewall might be forming.. need some new microwave images.. and its wobbling back more westerly..

thru 415pm.......i bet that the next move is NW....looks like stair stepping?

[Weatherfreak000]

It feels like Igor wants to trek as far west as possible.
