It was another dry, warm day, plus 2 degrees Celsius on the highest summit in Glencoe. The winds were light from a Southerly direction. The spring snowpack is generally consolidated and stable. Surface layers softened but stability remained good in most places. Some minor localised surface instabilities developed on some steeper slopes that were exposed to direct sunshine, mainly on North through East to South-East aspects above 850 metres. The avalanche hazard is Low.

Overnight, dry and cool conditions will continue to affected the area. Patchy light rain will commence in the early morning for a short period this will give a dusting of new snow on the higher summits. Winds will be fresh to strong over the summits form the South-South-Easterly direction. The freezing level will rise to well above the summits by the end of the period. Overnight, the snowpack will consolidate. Any new snow amounts are not expected to be significant mostly a light dusting above 900 metres. These new deposits will start to thaw and the surface layers will soften again as the freezing level rises but stability will remain generally good. Surface instabilities may exist in the afternoon, mainly on steep North through East to South-East aspects above 850 metres. Remaining cornices will be prone to collapse. The avalanche hazard will be Low.
