Cape Verde wave may develop...2:05 TWD info

[abajan]

That CV wave has good potential (IMHO).

I think everyone is getting a little edgy cause its a slow starting season...I want to start tracking as much as the next person... nit picking is so petty... come on guys.. When a storm forms, everyone will be buddies again...

The SAL is there. Dont be surprised if there is yet another surge behind the wave

FROM THE 2:05 TWD

TROPICAL WAVE REPOSITIONED ALONG 23W...BETWEEN THE COAST OF
AFRICA AND CAPE VERDE ISLANDS...S OF 17N MOVING W 15-20 KT. THE
00Z SOUNDING LAST NIGHT FROM DAKAR SHOWED THAT A PERTURBATION
HAD PASSED THE STATION ABOVE 650 MB WITH LITTLE SURFACE
REFLECTION. DOWNSTREAM...THE SAL CAPE VERDE 12Z SOUNDING SHOWS A
MID-LEVEL WIND SHIFT ABOVE 650 MB SIMILAR TO THE DAKAR
SOUNDING...INDICATING THAT THE LOW-LEVEL SIGNATURE HAS YET TO
PASS. A SQUALL LINE HAS MOVED QUICKLY WWD PAST THE ISLANDS ALONG
THE ITCZ...WITH WIDELY SCATTERED MODERATE CONVECTION NOW FROM
7N-11N BETWEEN 27W-34W. DRY SAHARAN AIR AND DUST IS MOVING OFF
THE AFRICAN COAST BEHIND THE SQUALL LINE...AND RELATIVE HUMIDITY
IS FALLING TO UNDER 20% PRIMARILY BELOW 750 MB.

In other words another one bites the dust.

Yes, Stormsfury is right...

That is correct Luis.. I totally agree with you....

Update: It looks like the system did not develop as I had thought, at least for now, and dry air is still taking its toll across the majority of the tropical Atlantic. I wouldn't worry, though, as I know this is the prime time of year for these SAL outbreaks. I would say in about 2 weeks, we can start seeing less of the SAL and more of the stronger waves off Africa.

By then, there will be practically nothing to stop these powerful waves....

[Steve H.]

Our wave at 40W is trying to re-fire convection again, as well as the one at east of the Windwards. Then there is the mess with the trough in the SE states....yuck. Think something may still come out of all this, atmosphere is moistening up over the Atlantic. Rumor has it that JB is hypothesizing something coming out of the mess in the GOM/SW Atlantic during the next week. Chin up all. Things will start happening

Actually, most every system is affected by the SAL. The SAL is always there. That appears to be what saved the Carib from Georges, a nice SAL intrusion (have the SSMI pass in the ppt presentation that I gave at the AMS conference, on the home page of nwhhc). Only very few CV systems completely escape the grasp of the sal

Thanks Derek for that info. Great Post!!
