[brunota2003]

8:05 P.M. Discussion: I believe this is the correct wave...
A WELL-DEFINED TROPICAL WAVE IS ALONG 26W/27W SOUTH OF 16N
MOVING WEST 15 KT. LOW-MID LEVEL CYCLONIC TURNING IS CLEARLY
EVIDENT ON SATELLITE IMAGERY. SCATTERED SHOWERS AND ISOLATED
TSTMS ARE WITHIN 180 NM EITHER SIDE OF THE WAVE AXIS.

Today's Discussion
A Slow Go in the Tropical Atlantic
Posted: 13-JUL-2006 5:59pm EDT

By AccuWeather.com Meteorologist Frank Strait



Another tropical wave is out over the open Atlantic to the southwest of the Cape Verde Islands along 27 west south of 14 north. There appears to be an area of low pressure along this wave centered near 27 west, 13 north. There is not much wind shear in this area, and the water temperatures, while not very warm, are warm enough to support a tropical cyclone. The limiting factor for this area is that Saharan dust and very dry air is present just to the north. Nevertheless, this area bears close watch over the next few days as it tracks westward at about 12 knots, and especially once it reaches warmer waters around 40 west.

if this isnt in the 1030 TWO i would be extrememly surprised...whether its a land threat or not, this deserves to be watched and needs to be recognized by the NHC

[AJC3]

Will the NHC put the floater on it soon?

I think it's still too far east for images every 30 mins.

That's right. The only reason I could get a full shot of it last hour was that it was 18Z. Once it moves west of about 31W it'll be in the regular northern hemisphere view.

It's a shame that the euro folks aren't a little more giving with their data. If you have a JAAWIN account , you can view MET-8 data every 15 minutes.

The "old" GOES satellite will be moved eastward over the central Atlantic in a few months. That'll provide imagery of the eastern Atlantic and western Africa either every 15 minutes or every 30 minutes. But I think that won't happen until September or October.

I'm on the SSD GOES-ops mailing list and I hadn't heard about this! In fact, after I read your reply, I surfed around the SSD site and still found nothing. Is there a site that has additional info on this?

In any event, I assume this would mean that GOES-13 is going to be brought out of storage and become the new GOES-E? Or is GOES-10 being moved and GOES-11 will remain GOES-E?

[P.K.]

You are correct. FREE images are available every 3 hours. Europe charges €€€€€€ for more frequent imagery, as they do for high-resolution ECMWF data. Maybe we can sell them the GFS? Perhaps give it to them?

I should be allowed it, I pay for it with taxes! The only time I got to see high resolution ECMWF data was at university. I do like this free GFS I can access though.

PS - EUMETSAT won't charge US$.

That would be really good but hopefully I'll have a job in meteorology by then anyway and access to MSG images.

check out this TC formation probability map...probably the best chance so far thsi year in the atlantic

here is a good loop of the area

They better be on the lookout in Nova Scotia

[cheezyWXguy]

ya I noticed that...kinda weird...thats the 1st time ive seen that blue on there in the atlantic, and definately the 1st time in the CV area

I wonder if NHC gets the more frequent images from Meteosat 8

[SouthFloridawx]

I'm sure they will if the convection persists around the low level swirl. It doesn't mean they aren't interested... it just means they don't have much to say about it yet. Clearly they mentioned it in the 805 TWD.

[cheezyWXguy]

does anyone have a sat loop that updates frequently of the africa coast and the cape verdes?

[SouthFloridawx]

A cut and paste from the above image posted by Luis.

It's still got an impressive spin but the convection is ragged and hardly noticable.


It's looking weak.

This is probably the best cyclonic turning with a wave we have had thus far this season.

Right now that's a good thing isn't it because it will more likely take a westerly track which will offer more favorable conidtions for the future?

Thers another monster wave getting ready to exit Africa

[Grease Monkey]

I'm not going to get excited until it proves itself over water.

[SouthFloridawx]

Mark my words... if convection continues to flare up we'll have 97L and not too long after that we'll have TD #2. We'll have 97L by tomorrow afternoon/evening but, I'm not going to venture out to say we'll have TD. 2.



This is probably the start of the Season IMO.

Also to note is that wave that canegirl mentioned above that is currently over africa about to exit and Probably the one that GFS was picking up on.
