Generally high. Lower confidence for the extent of any cloud breaks on Monday afternoon.
Poor visibility presents challenging route finding conditions. Visibility could be significantly less than 50 metres in all directions with few or no visual references, especially on featureless moors or plateaux. Distances become hard to judge and cliff or cornice edges can be difficult to recognise. These conditions require good navigational skills. There is a risk of white-out conditions when mist or fog is combined with extensive snow cover.
Patchy rain and extensive low cloud and hill fog. Drier and perhaps brighter in the east at times in the afternoon.
