ATL HANNA: Extratropical - Discussion

[cycloneye]

Here are both invests.

[pojo]

we were looking at this system today and wondering why NHC hadn't put the INVEST 95L tag on it......

painfully obvious of either an MLC or LLC...

If we don't go for 94L there is a good chance of flying 95L or both.

[Sanibel]

95L looks like it is curling up in those last frames. Longitude near 40W.

Should get a Floater on the next report.

[GeneratorPower]

I think it's pretty likely NHC had their hands full with Fay and didn't want to begin tracking 95L until they *had* to. Hence the delay.

Looks like you guys will stay busy for quite a while. Of course its not a surprise as its getting into late August.

[fasterdisaster]

I'm kinda beginning to wonder if 94L and 95L are going to eat each other apart.

[BigA]

I can't imagine that they would both cause the destruction of the other one, but it is certainly possible that the system that develops first (if either does) would absorb or destroy the laggard.

[Scorpion]

I would think that if 94L developed then 95L would wait until it was in the Western Caribbean or Gulf to develop.

I dont know. I think both 94 and 95 can develop. 94 has a pretty small circulation and they appear JUST far enough away from each other not to hinder each other too much. Although 94L could be the reason why theres more shear predicted for 95L than 94L

I think it's so cool to have an actual hurricane hunter on the board....You guys do a fantastic job by the way, especially considering the everchanging oceanic environments that you have to fly into.

[RL3AO]

I was waiting a long time for this to be tagged 95L. It looked awesome yesterday and still looks good today. Will the NHC mention it by 2:00 am?

They tagged it as an invest so there is no reason for them not to mention it.

Shows what I know. No mention in the 2am TWO.

[Cyclenall]

The NHC doesn't like this system. It has looked better than 94L for the past 38 hours and not a letter typed in the TWO.

[KWT]

Wow the Atlantic has come to life, this invest is also looking pretty likely I think to develop.

All these can develop, remember 1995 when we had 4 storms all develop pretty much in a row across the mid Atlantic.

I'm confused... 95L isn't mentioned on the NHC site nor or the Navy tropical weather site.
Who is naming invests?

[KWT]

This is looking increasingly impressive now and its held this presentation for a long time now with deep convection, think the chances are this one develops into a system sometime within the next 48hrs.

Maybe a computer malfunction at NRL? Anyway,from ATCF is where all invests are activated and deactivated,all by automated computers.Here is the site from that. By the way NRL still has Isselle there after days of last advisory.

This issue comes up almost every time there is a named storm and an invest.

I just don't subscribe to the belief that the attention span at the NHC does not allow for multiple systems to be observed and forecasted at once.

I respectfully disagree with that contention.

[KWT]

Yeah I think there is no reason to rush to upgrade this system for a while yet but it does look increasingly good right now and has gained a little bit of latitude. Would think this has a good chance of developing, prehaps sooner then 94L.

[wxman57]

Invest 95L is gone from the MRY web site as an invest. I think they're looking at the wrong area for possible development. 95L is part of a wave axis that extends northward to 20N. 95L is the base of the wave. But it's the top part of the wave that typically breaks off and develops. Yesterday, we could clearly see a large rotation at the "crest" of the wave. Look up near 18N/38W, there is convection firing over the broad LLC now. That's the area to watch for potential development.
