ATL: IGOR - Ex Hurricane - Discussion

[ozonepete]

Igor circulation and overall size remains much larger than the weakening Julia. While there might be some effects from the interaction, I don't expect Igor to do anything too erratic. I expect Julia to get sheared further and weaken, Igor will probably maintain his intensity and continue to expand. For a classic Fujiwhara effect to take place, the storms have to be nearly identical in their size and strength, otherwise the stronger, larger circulation disrupts the smaller, weaker circulation.

There are many significant interactions with BIG differences in strength:

Igor showing his new eye!

I plan to watch this weather buoy: http://www.ndbc.noaa.gov/station_page.php?station=41044

The closest point of approach should be within 10 miles in about 26 hours. If that is near peak intensity it could provide the hard data that the NHC likes to have befor a Cat 5 classification.

Wave height is already 24 feet.

If the buoy survives, it ought to get some great data.

Looks to be moving west again. Wonder how much the weakening from the EWRC has to do with this step moreso to the west?

use this site to estimate the distance of them:

they seem to have distance of 1400 miles right now

Try it again. I get 1100. Anyway, the important point is they could get close enough toi interact, and it would be fascinating to see.

Igor is a really massive storm now and looks like Bermuda is pretty much going to get a good bit out of this. Nice structure and continues expanding.

Both are now located at 20.2ºN, so 56.5ºW - 34.6ºW is 21.9 * 60 = 1314 nm * 1.152 = 1514 miles

I notice Igor's hurricane force winds extent has not changed that much, while tropical storm force winds have expanded a great deal.

HURRICANE FORCE WINDS EXTEND OUTWARD UP TO 45 MILES...75 KM...FROM
THE CENTER...AND TROPICAL STORM FORCE WINDS EXTEND OUTWARD UP TO 240
MILES...390 KM.

Thanks, Hurakan! I'm still thinking that they will get close enough for interaction if they continue at their present speeds.

Huge eye about to form.

WOW.

[emeraldislencguy]

they have just posted rip current and heavy surf warnings for the coast of nc
how high fo yall think the waves will get
also our local tv met sais the cape verde season is over due to the upwelling from all the hurricanes says they ahve caused the water to cool off
what do the pro mets think of this

[emeraldislencguy]

please excuse my bad spelling I should have turned the lights on

I don't want to startle anyone.

To help with showing how big Igor is, here's what it would look like in the Gulf of Mexico.

[South Texas Storms]

wow what a big bad boy.

WOW.

It'll should go annular at that point.

yes its going to be very large..

Shear and the warm SST's over Igor should preclude that.

But it will get pretty big. Somewhat concerned about wave/surge potential in Bermuda, even though this will likely be down a couple categories by the time it gets there.

The results given by the calculator at http://jan.ucc.nau.edu/~cvm/latlongdist.html for the 11 p.m. coordinates are 1234.4790 nautical miles and 1420.5882 statute miles.

The formerly-present feeder-bands and arcs are already dying as the new, huge eye firms up, and radial outflow aloft is now smothering everything in sight. I.e., annular. The storm is at the same longitude (55W) as Isabel when she evolved into a giant donutcane cat-5.

Unofficially, today will officially be "freak-out" day when the sats are splashed across the morning news.

[abajan]

IMHO there’s no hint of annularity. As a matter of fact, a vigorous feeder band seems to be developing on the southwestern side of Igor and the Leeward Islands may well experience squally weather at some point.
