Re: ATL: INVEST 99L - Models
Hope we can finally get some run to run consistency with 99l. Everytime it starts to pop up it gets squashed in the 00z run. Let's see what happens tonight.

Re: ATL: INVEST 99L - Discussion
I'd say there may finally be a fair chance of development come this weekend as it approaches the Bahamas. Ensembles strongly indicate a northward turn as it nears the U.S. They also indicate possible hurricane strength. May be a close call, or perhaps a hurricane impact in 7-8 days. Need to keep an eye on 99L.

I'll be in Baltimore over the weekend... if proto-possible-Gert were moving faster, that trip might be a bit more interesting.

Not a meteorologist, in fact more of an idiot than anything. You should probably check with the NHC or a local NWS office for official information.

My sister just moved to Mt Pleasant SC this week (from the west coast)...I sure hope I'm not going to have to drive down there and put up hurricane shutters this season

Re: ATL: INVEST 99L - Discussion
I think the collapse of the 500mb mid level circulation may finally help this consolidate at the lower levels and lead to something down the road. This thing has really struggled with an elongated circulation throughout most it's run with competing vorticity on the NE and SW sides pulling it apart.

Re: ATL: INVEST 99L - Discussion
8 PM TWO:

A trough of low pressure located about 1000 miles east of the Lesser
Antilles continues to produce disorganized cloudiness and showers.
Development of this system is not expected during the next few
days due to unfavorable environmental conditions. However, some
development of this system is possible by the weekend while the
system moves west-northwestward at about 15 mph over the western
Atlantic.
* Formation chance through 48 hours...low...near 0 percent.
* Formation chance through 5 days...low...20 percent

Anyone have the Euro spaghetti ensembles? I’m curious to see the tracks and intensities! Thanks.

@MJVentrice
12Z Calibrated ECMWF EPS up to 70% chance for development with regards to invest #99L, with a track towards the eastern U.S.

We know the GFS is not as good as the euro but check the facts with the track and timing. I am beginning to really tire of the model war crap that goes on around here.

Yeap, the GFS failed on developing the storm just 3 days ago but it has done better with the ridging holding strong to the north of it.

Completely agree. Literally finished rebuilding from Sandy this past June so I don't write anything off until it's long gone. Sadly, many people here (Jersey barriers) have dug in their heels on another devastating storm like Sandy, ever hitting here again.

I now solely use ensembles for hints of future TC development and when there is a storm to track, I split the solutions from the GFS and Euro.

Re: ATL: INVEST 99L - Discussion
Looking to sell what happens when the wave passes 55 west, sea surface temperatures really increase from then on.
We have seen many waves explode at that point if conditions are at least marginal.

The models often time have differing solutions and that is worthy of discussion.

Im thinking anywhere south of copans is in the clear, north of that watch out..
