Had a pan-round of the hi-res version, Nigel - everything else is scud, the long vortex being the sole 'smoothie'! I guess the fact that Cadair Idris rises like a wall with the winding and deep Dulas valley from Mach to Corris leading to its foot must promote a lot of local vorticity at low levels, especially in a southerly airflow as was the case Saturday. I know a lot of people who have seen funnels in this area - one was snapped in April this year during another convergence-type convective event, although this was in a NW airflow on the other side of Cadair - guess the process works both ways! The fact that the military jet photographers hang out in the vicinity to shoot jets going round the Mach Loop is starting to help in this context - it was one of those guys who got the April one! This is the fifth funnel I've photographed from pretty much the same spot - and I bet I've missed plenty by being elsewhere at the time!
