Two African waves worth mentioning
There are two African tropical waves worth mentioning today, though neither looks particularly threatening. A tropical wave near 12N 45W, about 1200 miles east of the Lesser Antilles Islands (97 L), is moving west at 15 - 20 mph. This wave is now surrounded by an area of very dry air from the Sahara Desert. The dry air has disrupted most of the wave's heavy thunderstorm activity, and will continue to make it difficult for this system to develop over the next 2 - 3 days. Wind shear is a modest 10 knots over the disturbance, and should remain in the moderate 10 - 15 knot range over the next 2 - 3 days. Thereafter, shear is expected to rise to 20 - 30 knots. This morning's QuikSCAT pass showed no evidence of a surface circulation, and only a modest wind shift associated with 97L. The National Hurricane Center is giving this system a low (less than 30% chance) of developing into a tropical depression in the next 48 hours.
A second tropical wave now approaching the northern Lesser Antilles Islands is under 30 knots of wind shear, and has little prospect of development due to the high shear. However, the wave will bring heavy rain to the islands over the next two days.
None of the computer models are forecasting tropical storm development over the next seven days, and I don't expect either of the two African waves mentioned today to develop over at least the next three days.

I'll have an update Sunday afternoon.

But not until the NAVY or NHC calls it.
A floater is always on the Fray early.
97 is das kaput.
Its behind enough Dry air to make a New Sahara.
lmao!
i like mine browned

Tropical Disturbance Summary (1800z 18JUL)
=========================================
At 3:00 AM JST, Low Pressure Area (1008 hPa) located at 10.0N 135.0E has 10 minute sustained winds of 15-20 knots and is reported as almost stationary
97L is still an invest, somehow.

Das Kaput.
Hi Weather456 welcome back
welcome back 456
not sure what i think of all that Weather since i'm on southeast coast

Nothng to worry about now since there is nothing there. Just keep an eye out if anything develops.
On the chart, the time frame is between 72 hrs and 1 week. I think Dr. Masters posted his update before the 12Z runs, but some models, like the CMC wa showing it since yesterday. I don't really understand what he meant.
And thanks everyone.
Floater - Water Vapor Loop
Only East coast Genesis comes out the GOM here.
All it means we should monitor that wave. That wave has had model support from day one (when it was near 40W around last Monday), but it was inconsistent at first, not the models seem to think it will develop.
Thanks!
The only Circulation seen in the Whole Basin is here,west of the Islands..moving W to WNW around 24mph
Well what ur looking at is the 18Z run and only 1 model is out that fast, the NAM, which isn't popular when it comes to tropical cyclones. Also, the models were at the 12Z time frame.
here's the CMC for example.
12Z GFS
12Z UKMET
Thats kinda a water shed run Id say.
lol ok
What are your thoughts on Ex 97L as it enters the "sweet spot" near the Antilles?
Especially in that water
well Pat that looks like it could develop and affect Fla and it looks like it heads straight to where i live too. Im talkin about your cyclogenesis map of the GOM blob there. What would be the strength of that??
