I have friends travelling up from South Wales wednesday should I worry
about them or maybe warm them to take the M5 instead of the A roads?
Their route seems right in the firing line for a possible 25cm of

I think the short answer is "yes", although we will have a better idea
of Wednesday's likely weather in another 24 hours.
