SST’s are warmish enough (23c-34c) to support cyclone development and latest satellite numbers now support 60 knt winds! However Vince is a very small system and will soon be absorbed by a cold front that is surging south East towards it.
Interesting that some of our higher tornado days (numbers wise) in North West Europe occur from frontal passages that contain tropical air.
From the TORRO FAQ.
The largest tornado outbreak in Britain is also the largest tornado outbreak known anywhere in Europe. On November 21, 1981, 105 tornadoes were spawned by a cold front in the space of 5.25 hours. Excepting Derbyshire, every county in a triangular area from Gwynedd to Humberside to Essex was hit by at least one tornado, while Norfolk was hit by at least 13. Very fortunately most tornadoes were short-lived and also weak (the strongest was around T5 on the TORRO Tornado Scale) and no deaths occurred.
