...TROPICAL WAVES...

A tropical wave is in the eastern Atlantic from 09N-19N with axis
near 22W, forecast to move at 10-15 kt within the next 24 hours.
Scatterometer data show there is a low center associated with the
wave with pressure of 1010 mb. Meteosat composite imagery show
Saharan dry air and dust engulfing the northern wave environment.
A surge of moderate moist air from surface to 850 mb and divergent
flow in the middle to upper levels support an elongated cluster
of moderate to isolated strong convection from 10N-13N between
18W and 25W.

Here is our TW/Low in 72 hours...

Nice ball of convention and spin with it. time will tell

[RL3AO]

It's taking advantage of the fairly far north monsoon trough and favorable environment. However, convection will probably get suppressed as it moves west and detaches from ITCZ/trough.

[JaxGator]

Looks good on satellite with nice convection. Could the wave be able to have its own moisture envelope before it would detach from ITCZ/trough?

Isn't this the Tropical Wave the GFS was developing for several runs about 5-6 days ago?

I think so. Today or yesterday was the day it was supposed to make splashdown.

[JaxGator]

For now, it has some moisture to work with (far right).

SAL is an issue but I did find these graphics that show moisture and dry air in the mid and upper levels.
Mid level:

Upper level:

We'll see. Maybe it could develop down the road.

[Gustywind]

Thanks for reply guys . Again, let's wait and see if something could happen with this twave.

The 12Z GEM develops this in the long-range (off Southeast US. coast). Normally I would say forget it but the GEM has been way more conservative this year with the upgrade not showing the phantoms storms it has been known to show in previous years.

[RL3AO]

I think it's worth watching as it goes north of the islands for sure.

[chaser1]

Looks to me like the air ahead of it has moistened up a bit, at least up to about 40W. I'm guessing that this wave will likely sacrafice itself to further breakdown some of the mid-Atlantic MDR region SAL out there. Like others have pondered though, thats not to say that it wont suddently find "that sweet spot" and find itself newly developing convection as it approaches the islands or the S.E. Conus.

Tropical Weather Discussion...correction for satellite time
NWS National Hurricane Center Miami FL
205 PM EDT TUE JUL 26 2016



Tropical wave in the east Tropical Atlantic extends along 23N
from 9N-17N moving west moving west near 10 kt over the past 12
hours. The latest scatterometer pass indicates the low is no
longer on the surface. There is a mid level low observed on the
visible satellite imagery. Wave coincides with a 700 mb low as
depicted in the global models and within a high amplitude surge
of moisture as seen on the SSMI Total Precipitable Water
imagery. Scattered moderate convection is from 9N-13N between 20w-
26W.

Strongest signature I've seen on the ECMWF operational run so far for our wave:

What's the link to that NCEP ensembles probabilities page?

[RL3AO]

Is it this wave the Euro is developing? It's already nearing 25W and the Euro develops something near 30 in 4 days.
