One tropical wave to watch in the mid-Atlantic

A tropical wave that emerged from the coast of Africa late last week is now near 8N 35W, way out in the middle of the Atlantic. This wave has heavy thunderstorm activity and some counterclockwise spin to it, as seen on both visible satellite loops and QuikSCAT. Wind shear is 10-20 knots, and is forecast to fluctuate between 10 and 30 knots in the region over the next two days. Sea surface temperatures are 27-28 C, which is warm enough to support some tropical development. Dry air does not seem to be a hindrance, as the Saharan Air Layer is about 150 miles to the north of the wave. The GFS model does indicate a tropical depression might form here, although our other three reliable models, the NOGAPS, UKMET, and ECMWF, do not. Climatologically, formation of a tropical depression in this region of the Atlantic this time of year is quite rare. Due to this fact, plus the somewhat marginal wind shear and the position of the wave so close to the Equator, I'm not expecting it to develop. However, we should keep an eye on it this week as it moves very slowly to the west at less than 5 mph.



I'll be back this afternoon with my bi-monthly hurricane outlook, for the first half of July.

Drakoen maybe you can answer my question is there a year like this where there were waves off of Africa becuase last year I dont remember this or 2004 and 2005 but I dont know

Most of 2005 hurricanes didn't develop until the Caribbean. 2004 was mainly a Cape Verde year.

Drak the CMC looks like it makes it to the Carib, but much weaker


in terms of strength you can't look that far out.i would trust the run up to about 60 hours or so.

Wave looks like it has good structure to me...I'll wishcast it right over 30N 65W going north-no harm to anyone except ridable surf-heck, the disturbance off of Florida pulsed some fun 4' waves on Saturday-I'm still sore from the session.

Yeah Drakoen. My previous comment took all of that into account. And some nice images subsequent to that, kind of confirmed my thinking. Well, we watch and wait........

Probably to far south to start the real Cape Verde machine. Once the ITCZ get to 10N than it will really get cooking.

SAL & Shear dont give any indication of affecting it. This has a shot.

Isn't it a little early to start the wave train........

lol pottery read Jeff post at the top, read the NHC, look at the SFC analysis. there is cyclonic turning which is very evident on the animated Satellite loop. I feel this system only need more organization in the way of convection to become a TD. I don't want to jump the gun but thats what i seems to me.
here the LOW cloud Sat
