Description:
We are currently experiencing a warm West to NW flow and the freezing level is due to rise to 2800m today. If temperatures rise rapidly we could see the surface soften quickly and this in turn, could lead to an increase in wet slide activity particularly during the middle of the day.Pin wheeling, sluffs and small point releases are signs that rapid heating is occurring. Avoid steep,unsupported solar aspects if the snow under your skis or board is becoming very soft or slushy - move to a cooler aspect.

Recent Avalanche Activity

Recent Avalanche Activity
No avalanches reported during the past 24 hours. A size 1 wet slide reported (140928) steep NE facing slope surrounded by rock. Also, size 1.5 wet slide was reported (140927) NE aspect, 1700m. The failure occurred to ground in a steep, unsupported zone surrounded by rock walls following a 3 degree spike in temperature in the middle of the day.

Current Snowpack Conditions

Current Snowpack Conditions
Warm temperatures and a melt freeze cycle over the past few days have helped to consolidate the mid and lower pack.Prior to last weeks snowfalls from the W1/2, areas of melt/freeze crust were widespread especially on the solar aspects (East through North to West) . Facetted snow (loose and sugary ) has existed in places both on the surface and in buried layers, especially on cold, shady slopes (South and SE aspects). Below about 1600m, the cover is either very thin or has already disappeared.

Mountain Weather

Sliding Danger

Slide For Life
Areas of melt/freeze crust are currently widespread. As a result, you could take a long, uncontrolled slide if you fall over. Remain alert as to where you would end up if you took a slide and exercise extra caution if the run out is poor.With Spring melt/freeze conditions, it is worth considering adding ski crampons or crampons and an axe to your pack along with plenty of sunscreen.
