Ex Invest 90L

[KWT]

Honeyko, it may look like that but looking at the vis.imagery all I see is the clouds your seeing dieing off possibly making the illusion of getting sucked in...besides to make the idea of them being' sucked in' by that blob they would have to probably move at 20-30mph eastwards against the mean airflow which I have a very hard time accepting would be the case.

[Honeyko]

(That blob is very, very low, too; right about where Ivan started.)

Are you sure, Ivan was not much lower? At 9,5 north 25,4 west?

The blob is currently at 8N, 20W.

What "mean airflow" are you talking about?

Look at about 9N, 33W (about halfway between 90L and the blob); surface flow is toward the blob, not 90L. Without southeast surface inflow, 90L will be strangled.

-- And, in all the years I've been watching central Atlantic systems, I have never, ever seen a weak middle system in a NW/SE oriented line of storms along a west-advancing SAL boundary develop into a hurricane. It is always crushed while one or the other or both of the others develop further. Given that 90L has a lousier satellite representation than the other two already, and the SAL boundary is now a damn near straight line from 99L to the blob, 90L's hours are numbered.

[KWT]

The easterlies that are present in the Atlantic at that latitude, the same easterlies that is driving the SAL westwards and has probably been shearing 90L from the east. IMO this is the major problem for 90L as its forcing the SAL into the system and also displacing the convection somewhat further west of the wave axis.

I think that blob to the SE is simply a ITCZ flare-up right now, no more or no less though its August and they do sometimes pull surprises at this time of year so may need watching just in case.

As it happens I do recall a similar thing happening with pre-Dolly with that huge ITCZ blow up that was to the south of the system stealing its inflow as well.

Loop with 90L and ITCZ blobs



Why there is no SSD floater on 90L ?

[Chacor]

Probably because development isn't expected.

DISTURBED WEATHER ASSOCIATED WITH A TROPICAL WAVE LOCATED ABOUT 800
MILES WEST-SOUTHWEST OF THE CAPE VERDE ISLANDS IS VERY POORLY
ORGANIZED. DEVELOPMENT OF THIS SYSTEM IS UNLIKELY AS IT MOVES
WESTWARD NEAR 20 MPH.

If things continue as they are now,I can see them deactivating the invest later today.

[Matt-hurricanewatcher]

I agree cycloneye, the SAL has destroyed this. I don't think it has any chance in the next 48-60 hours. The MDR appears to be shutting down, possibly because of a strengthing East Atlantic subtropical high forcing SAL over the ocean.

[cycloneye]

90L has been eliminated from our automatic graphic at the top of forum.

[KWT]

Indeed Matt probably still 15 days too early for any major developments in this region.

Still I think much further west closer to the Caribbean this may need to be watched again just in case...

[cycloneye]

And here is the dagger,deactivated.Now this thread will return to Talking Tropics forum for the members to continue to post comments about the system there.If it is tagged again,it will return to active storms forum.

see, just as expected... it will be poof.... none of these 3 invests will form

[KWT]

Well 90L is gone but 91L is in a very good set-up which has got the pro mets expecting development, 99L also has had a fair convective blow up just recently as well.

[Mecklenburg]

i really was counting on this one at first to be an impressive long-tracked major hurricane like Dean but i was dismayed.

[Sanibel]

I have never, ever seen a weak middle system in a NW/SE oriented line of storms along a west-advancing SAL boundary develop into a hurricane. It is always crushed while one or the other or both of the others develop further.

I was trying to say that it was too close to 99L. This one really collapsed. Didn't expect that.

[Mecklenburg]

i was really disappointed with 90L, i think i'm going to cry....

I don't think you're making friends with our posters in the Caribbean.

Tkanks a lot i'm glad to see a pertinent post like yours Ed Mahmoud i congratulate you... Whereas i have post recently a reply about the fact thatwe should try to think first before answering, something to meditate....

[lonelymike]

Why would you be disappointed a tropical wave doesn't develop? If you lived on gulf or atlantic coasts I don't think you would have those sentiments.

[HURAKAN]

On average, out of 100 waves, only 10 develop, 1 in every 10. You get a lot of disappointments. You just get used to live with them or you get use to expect them!
