Rain or sleet, feeling very cold at altitude with icy paths. Drier later, but still cold.
Occasionally heavy rain during the morning will turn to sleet above 600 metres, with very poor visibility in cloud cover. Mountain paths may be difficult to follow and become icy above 700 metres. Feeling very cold as strong northerly winds develop.
