yet the map showing contours of probability of disruption does not appear
to take elevation into account. .

The maps very rarely do. In the SW they almost invariably show the risk of
disruption due to snow the same for Mount's Bay as the top of Dartmoor. It's
hard to see how such a forecast could ever be regarded as accurate.

One thing I would really like to know, which I've asked before but never got
an answer, is how the MetO determine the accuracy of all these % forecasts,
especially when they cover such diverse areas.
