2011 Tropical Waves

[NDG]

Latest GFS is painting the same picture as it happened with 94L.
As this tropical wave that is entering the eastern Caribbean reaches the central and western Caribbean it will be interacting with yet another UL trough in the eastern GOM/western Carib and as another system gets going in the eastern Pacific. This tropical wave looks like it will get the Caribbean disturbed once again but it may not get a chance for best development until it reaches extreme western Caribbean or BOC, if at all.

Wave # 13 Introduced at 6/21/11 on 18z around 17W

This wave is the most northward in latitud that has been introduced so far this year.IMO,in part, the cooling of the Gulf of Guinea factor is starting to have effects in that part of the world with the moonson trough way up in latitud.

So far some of them have been pretty impressive, and though I mentioned a slow start to things (until Arlene), my thoughts over the past couple of months is that this season might be more of a problem than the past 3 or 4...

I didnt know where to post it so I'm going to try it here. I see in the Central and Eastern Atlantic loop what looks like a large wave @ 20 N 39 W. I don't see introduced as a wave but sure looks like 1 to me.
Looks like it will travel SW or WSW for a day or 2 taking it into a moister atmosphere with warmer waters and father away from that UUL. It's in the desert of the Central Atlantic right now but in a couple of day if it holds together could be something to watch. We'll see I'm just a little bored.

Dust Storm Shrouds Algeria And Mali


A dust storm blew through parts of Algeria and Mali on Sunday and Monday. The storm was so large that parts the north African nations were hidden when the Moderate Resolution Imaging Spectroradiometer (MODIS) on NASA’s Terra satellite captured the below natural-colour image on July 10, 2011.




In places, the airborne dust forms a camel-coloured cloud thick enough to completely hide the land surface below, especially near the Algeria-Mali border. The dark land surface northeast of the storm is the relatively high, rocky ground of Tassili n’Ajjer National Park where stone forests.

Source points for the dust storm are not obvious in this image, but a massive sand sea known as Erg Chech covers parts of northeastern Mali and western Algeria. The shifting dunes of this region provide plentiful material for dust storms.

WOW! you must be bored. That thing looks weak but I see your point of view. Time will tell, IF it can get past the liquid Sahara it's going through.

Is this part of the wave that is just east of the Cape Verde Islands?

Its been a long time that I've seen this many ducks in a row.
