However its not been tagged on ATCF so the NHC had nothing to do with it.

Still, this is a step in the right direction and if the NHC decides to jump on board they would certainly have to expand the name lists.

Winds were below storm strength (35 kt) in the western Mediterranean, both yesterday and today. Estimated pressure of the low has gone up from 1000 to 1005 hPa.
Analyses maps from UKMO, DWD, KNMI all show a baroclinic system.
Yesterday around 15-18Z the center of the system was slowly moving southward over Menorca (LEHM), with wind shifting from WSW to NE. No change in temperatures was measured.

Looking like a (sub)tropical system doesn't mean it has to be one. Occasionally we have had lows with an eye feature over the Netherlands (as well as polar lows of course).

I am very sorry that the analysis begins only now that the system is weakening; Previously was much more 'intense convection and in the top cloudsImage

This is a historical day in tropical meteorology and I am glad to be part of the people witnessing this moment live in a weather forum.

No, seriously, this has to be the first time they use the "M". I'm wondering if they start numbering the invest separately next year (90M, 91M, ...)

Just an FYI. http://www.ssd.noaa.gov/PS/TROP/2011/bulletins/archive.html - they've been doing tests all year, it seems, so they could be ready for this very event.

This being the first system after officially, BUT not be the first tropical system in the Mediterranean Sea.

I emailed the NHC and got this response.

Thank you for your e-mail.

Despite the "L", Invest 99 is not under the jurisdiction of the National Hurricane Center, as the location of the Invest is not in the range of our ATCF software. The request for an Invest came from the U.S. Navy, which went to the Satellite Analysis Branch for a classification. An Invest simply means that more information on a particular weather system is being requested, and in no way implies there is any threat of tropical cyclone development...which does not occur in the Mediterranean Sea. For more information, I would recommend your contacting the NRL at 831-656-4833.

Best regards,

Dennis Feltgen


So nothing from NHC then, just for confirmation.

Probably about 50 kt at its peak intensity, given that the T2.5 might be a bit low and that it was after peak I would think. I'd go with 40 kt now.

What would a storm of 65 kt or higher that is a tropical cyclone be called there?

I looked on this forum and saw "Mediterranean Sea"... now this basin is more active than the Atlantic? This has been a year.

That's a letdown. And I was hoping that this would be officially classified.

If it is seen as a windstorm, then "uragano" (Italy) or "ouragan" (France).

A tropical system would be a "ciclone tropicale" (Italy) or a "tempête tropicale" (France)
