Tropical Wave Near the Coast of Africa (Is Invest 93L)

[bob rulz]

Does ASCAT analyze systems this far east?

[IsabelaWeather]

Not mentioned in the 2pm TWO which is a little surprising. The wave clearly has a good amount of mid-level rotation and decent conditions ahead of it for the next day or so. The GFS does develop this slightly but dissipates it after passing the islands.

Wouldn't even look at long range GFS forecasts

I believe he was talking about the Cabo verde islands and not the Antilles.

Whoops, yes I was! Probably should have specified which islands.

Does ASCAT analyze systems this far east?

Yes. ASCAT is a polar-orbiting environmental satellite (POES), and all POES circumnavigate the entire globe.

One issue is that its coverage swaths are have gaps due to the limitation of its field of view.

Good to know, all this time tracking hurricanes and I never really knew this.

Is that field of view limitation why ASCAT sometimes misses systems?

Regardless would be interesting to see what ASCAT would find in this system. Same as others, I'm surprised NHC didn't at least mention this in the TWO

[EquusStorm]

I think ASCAT missed it most recently, assuming it was even fully offshore then; hopefully it holds together until we can get a pass over it

[tiger_deF]

Where could I find a satellite loop of that location?

[EquusStorm]

Weathernerds.org has a great custom loop feature, that's where I usually go

[northjaxpro]

Not even a mention from the NHC? What??

Any model develops this?

I commented on this system yesterday..This is the best looking system to emerge off the Africa Coast so far.

It is no question in my skilled analysis that this is a full fledged TC right now ,and a very healthy one at that!

Check out the ASCAT web pages for METOP-A and METOP-B to get a good feel for what the global swath coverage looks like...

This was the last decent ASCAT pass I remember seeing (0947 UTC or 547 AM EDT)

[AnnularCane]

What is supposed to make this turn NW so soon? Seems like a waste of such a beautiful wave.

[abajan]

Where could I find a satellite loop of that location?

The Tropical Tidbits satellite page, and also Weathernerds (as EquusStorm mentioned)

[HurricaneEnzo]

Looks like it is pretty much stalled off the African coast. Is that odd? I don't really recall ever seeing it. Will will the wave about to come off the African coast push it away or will it eat the wave?

Why hasn’t the NHC given this development chances already!? I mean it looks more impressive than PTC-9!

Do you think it has a chance to be named or is there some doom in its future keeping the NHC from giving it a mention?

[MetroMike]

Wasn't this suppose to have a chance to develop but only to re-curve shortly thereafter?
Would not be naming that if I had the choice.

This is something you’d expect to see in late August into September, not late July. The NHC is sound asleep on this one.

This is quite unsettling when the average peak of the season is in September. Of course, it is possible that the peak could occur in August this year. The peak isn't always in September. Either way, we need to monitor closely these systems emerging off the African coast. If shear and dry air diminish soon, storms could start to organize much faster than Isaias.
