Olga is the name of the low in Europe today

[somethingfunny]

Although it's clearly not tropical anymore, if it actually was at one time, it looks like the circulation center can be tracked all the way to a landfall near Genoa, Italy.

[DanieleItalyRm]

Very like tropical storm in two fases and subtropical storm over Canary Is. and in final part to landfall. The depression dissipated in Mediterranean sea over Balearic Is.
I think it became into tropical caracteristic for the tropical transition, like Karl, Vince, Grace and many Mediterranean tropical cyclones (subtropical/high latitude and over 17-24°C sea surface).

Landfall:

I got this on my e-mail

ATLANTIC (ATL) - North Atlantic Ocean, Caribbean Sea, Gulf of Mexico


Canary Islands LOW
------------------

I do not have a track for this system, but I wanted to include a
few brief comments by way of documenting an interesting eastern
Atlantic low-pressure system in early February. A 1045 UTC visible
image made on the morning of 1 February depicts a LOW to the west-
southwest of the Canary Islands. The system was characterized by
convection which had wrapped around the low-level center, and some of
the models had analyzed the system as symmetric warm core on the
preceding day. According to Sheldon Kusselson of the Satellite
Analysis Branch, precipitable water values near the center were running
about 150 to 175% of normal--very unusual for that location at that
time of year. NHC considered opening an invest on the system, but the
convection soon became sheared so no invest was opened.

After the weakening LOW had become sheared and moved to the north of
the Canary Islands, Julian Heming of the UK Met. Office noted that its
appearance was similar to Hurricane Vince of 2005 after it had become
sheared and weakened. Julian reported on 2 February that on the
previous day he had noted a couple of 35-kt wind barbs in ASCAT data.

On 4 February, as the LOW was approaching the Straits of Gibraltar
area, convection made a comeback and an image at 04/1945 UTC depicts
a sort of "eye-like feature". A weather station at Gibraltar reported
64 mm of rain from 04/0000 to 04/0600 UTC.

According to Jack Beven of NHC, there are no formal plans to add
this system as an unnamed subtropical storm. Jack indicated that there
appeared to be a frontal structure connected with the system when it
looked at its convective best on 1 February.

Well... I would like to have seen this low close to the coast of EEUU. Then, I'm sure it would have had a different consideration from the NHC, before & after.

[Hurricaneman]

Theres a chance that this may be included in the TCRs at the end of the year

Are yo really sure?

It would be the first subtropical system in the history which make landfall in Spain...

Anyone knows more?

[Pedro Fernández]

Good evening all!

I have just posted something very interesting about this issue in Cazatormentas.Net. I'll leave you a link to our post there, and an explanation that what I have just discovered.

http://www.cazatormentas.net/foro/segui ... 26398/#new

Extracting from EUMETSAT...:

A tropical storm over the Canary Islands brings a strong surge and 200 mm of rain over a period of two hours, resulting in flooded streets, closed schools and disrupted telephone communications

Here is an 13MB mpg animation (Quick Time for Windows is needed): http://oiswww.eumetsat.org/WEBOPS/media ... t_loop.mpg

Who is right? Who is wrong? This is the question.

I agree with this explanation, of course

PS: If you use this info in other weather forum, a quote would be very appreciated.

[Derek Ortt]

I'll ask around at the AMS conference in Tuscon in a couple of weeks

Thanks for the anwer, we are waiting you since NOW

[pepeavilenho]

The conference in Tucson, Arizona, starts 10 and finish 14 of May

We are waiting your answer Derek Ortt
Thanks for all.

[pepeavilenho]

Do we have news?

[Derek Ortt]

all info from the AMS conference is in the PNJ.com postings

This question was addressed there. Day 1 or 2 of the conference

During the poster session, I had the chance to speak to Dr. Jack Beven, hurricane specialist at the National Hurricane Center. One of the topics I discussed with him was whether or not we already had a tropical storm this season. In February, there was a suspicious storm near Spain. Reports from the Canary Islands indicated it was a tropical storm. This was not the case according to Dr. Beven as the system was still frontal. The storm did detach from the front as it neared mainland Portugal. However, I was informed that there were no definitive reports of tropical storm force winds over the water or land. Therefore, according to Dr. Beven, this system is not likely to receive a post season upgrade to a tropical or subtropical storm, unless additional data is found.

Unfortunately, we will never really know because of the lack of information

[Pedro Fernández]

Ok......... At the end, I think that a name for this system is not the most important thing; as the thing really important is the development of that system (and its nature) in these environmental conditions.

From 2005 VINCE, I think there is a new point of view in tropical development...........................

Thanks Derek, and thanks Hurakan

Finally it looks like it won't be named...doesn't matter, because we had a good time watching it.
