As you able extratropical see in this system? For me this system is more evident like tropical or subtropical, rather than extratropical;

This storm is an example for tropical transition; A extratropical cyclone has acquired warm core and become in Subtropical and successively in a tropical cyclone (for example, tropica cyclone Karl, Grace and Vince it derived from tropical transition).
It Probably a Tropical Storm intensity.

Sorry for offtopic,but Tolakram,you forgot to move my post with ASCAT passes ;)

It is embedded in broad low pressure area and well organized.

Cloud tops are colder than -50 Celsius on the LLCC,and colder than -60 west of the LLCC.

This looks better than many of the Mediterranean systems we've seen. It's crazy how much more frequent they have become.

Does anyone know what Meteo-France is saying? Surely there must be some sort of weather map that would show the low. It'd be interesting to see what pressure they'd assign it.

This weather map is by the German met service of the university of Berlin.
You can see the LPA named "Rolf" with a pressure lower than 1005 mbars.
The time of the map is indicated on the bottom left.

this map to be very general. Other times we have shown that these maps can not see the real pressure into this small mediterranean tropical system.

Could be. Maybe it's just an estimation of the general pressure in that area, but they actually do pretty good with estimating pressures in extratropical windstorms.
But still these tropical/ subtropical systems tend to have a much tighter pressure gradient near the center, so a 1000-1002 serms reasonable.
