While daily forecasts have come to an end, SAIS said visitors to the hills should be alert to snow patches posing potential slip and fall hazards.
It said snow cover persisted in all mountain areas mostly above 900m (2,953ft), and there was still extensive snow cover at summit levels, notably in the Northern Cairngorms and Ben Nevis areas.
