Subtropical Development in the NE Atlantic? New System

[CrazyC83]

Again, remember that the NWS has no high seas control east of 33°W. They have to confer with the appropriate weather service (Meteo-France) before doing anything.

MF have this as a 1007 mbar low.

Part 2 : General synopsis, Sunday 21 at 12 UTC

Thundery low 1007 33N17W, moving east and filling, expected 1011
just near cape Sao Vicente by 23/00UTC.

What does that mean? Meteo-France has first control over the region?

[Chacor]

What it means is that east of 35°W (not 33°W as I earlier said) Meteo-France is tasked by WMO under the GMDSS to issue NAVTEX and high seas warnings for METAREA II.

You should NOT be using the NHC headers. You have no right to do so.

littlevince, I don't understand why the NHC is not paying any attention to this system. That's clearly a subtropical or tropical system. Extratropical systems are not like that.

I feel this is a tropical storm...This thing is blowing up a cdo over a LLC. I don't care where it is at, that is a storm. We will see if it is upgraded after the seasons over.

Now:

Clearly exposed now with almost no deep convection near the centre. Latest bulletin (0900z) from M-F notes a 1009 hPa low "moving east and filling".

Continues to rain over the southern part of the Iberian Peninsula.

A new system develops and I will keep an eye on it!

[HURAKAN]

A system to watch.

12z: Stationary!

12Z GFS seems to lose the current system South of the Azores and develops a new intense low. The original lows remnants do look as if drawn in. Looks like it starts off as an occlusion, but becomes symmetric with time.
