Hybrid low near the Iberian Peninsula

[Vince_and_Grace_fan]

In the night hours, the low currently approaching the Iberian Peninsula has developed more organized convection, and it looks qiute subtropical right now. ASCAT indicated maximum winds of 40-45 kt in the last evening.

If this ended up getting named by the NHC, it would be named Vince... which is interesting, given 2005 also had a Vince around the same area in October.

Convection near the core + well defined low level circ. I'd say if it were to lose its frontal structure that this would easily be a subtropical storm.

The cyclone made landfall near Faro around 15 UTC and its structure degraded a bit by that time, however, the Spanish weather radar still showed well-defined curved band on the north side and the core was also visible over the sea before the landfall.
The pressure decreased to 988 hPa in Faro with maximum gust of 83 km/h (45 kt) - the sustained wind data were not available -, also it fell more than 80 mm rain from the low. https://www.infoclimat.fr/observations-meteo/temps-reel/faro-aeroporto/08554.html

I'm gonna go ahead and predict this gets an update postseason. Was at least briefly a weak STS possibly borderline TS.

I'm almost 100 percent sure that it won't be upgraded to a STS, let alone a TS. I went back and looked at the hourly surface analyses on the Meteocentre web site leading up to the time of landfall. The cyclone never shed it's frontal structure. Surface temps were in the lower 20s (C) over southern Spain, south of the warm front, while they were in the lower to mid teens over Portugal. That converts into about a 12-18F temperature gradient, which is embedded in the middle of and elongated pressure trough, right where you'd expect the warm front to be (granted, METARs suggest that the LLCC is much closer to the Iberian coast than the analysis. Additionaly, it may have occluded prior to landfall (I don't have the actual frontal analyses to look at), however, based on satellite imagery it didn't develop warm seclusion. Moreover, the central convection assumed the form of a baroclnic leaf along the system's northern flank pretty quickly.

It can be argued pretty easily that the low had hybrid characteristics, but at best remained a frontal hybrid.
