In view of the forecast and looking at various radar predictions I have decided to call this one off. It is a longish exposed walk with no shelter whatsoever, and the BBC site states “heavy rain and a moderate breeze” from 10 a.m. onwards, and the % chance of rain is from 70% up to 100% as the afternoon progresses.
I certainly don’t relish the idea. Apologies to anyone who would want to ‘give it a go’.
