Low cloud and visibility

Extensive low cloud around for much of the morning with bases between 500-600m, this will shroud highest peaks at times. Though the afternoon main cloud bases are expected to be above summits although some patchy cloud may drift across peaks through the afternoon with the some brighter periods possible. Patchy cloud is expected to reform into the evening once again obstructing the highest routes. Generally good visibilities expected, but may be poor or very poor in low cloud or hill fog. Visibilities may drop to moderate or poor in heavy downpours.
