We're not in Devon any more, Moosifer.
Turns out that thunderstorm which kept me in the office on Monday was more entertaining than I realised, as a tornado formed on the outskirts of Dartmoor. This is Devon (WMN) report
Met Office spokesman Nigel Bolton said: 'Strong winds moved up from the south towards Tiverton, just as winds moved in from the north. A thunderstorm was already brewing and when the two winds met, they rose into the storm and caused a short-lived tornado across the northern fringes of Dartmoor.'However, an older report remarks tornadoes are not that rare even in Devon and another site describes the waterspout in the Bristol Channel.
I have this terrible urge to start wearing gingham and plaits.
