There's a bit of inconsistency in the warning on the Met Office website.
The text says

"the greatest risk of disruption will be focussed over high ground"

yet the map showing contours of probability of disruption does not appear
to take elevation into account. For example, it shows a higher probability
of disruption in Carlisle than over the Pennines.

Why 'focused'? It's arguable, I suppose, that a risk can be
'focused'. But surely not 'the greatest risk'. That's tautological.
And, because the emphasis is on the first syllable, it is
normally spelt with one 's'. Simple English helps make the
warning clear: "The greatest risk is over high ground." I continue
to argue that it is outside the expertise of weather forecasters to
assess risk of 'disruption', a word that is never defined in this
context.
