Alpine level
High Alpine: Above 2000m
Alpine: 1000 to 2000m
Low Alpine: Below 1000m
Description:
The snow from last weeks storm cycle has either been capped by a raincrust at low or mid elevations or will have for the most part settled out. As there are still going to be several layers existing within the snowpack, we still can't completely put the potential of isolated windslab weaknesses to bed.

Recent Avalanche Activity

Recent Avalanche Activity
Quite a lot of activity from loose wet and small slabs late last week.
Nothing new other than ice serac collapses in the warm temperatures reported.

Current Snowpack Conditions

Current Snowpack Conditions
The snowpack is still layered with a wet grain crust in places.
Deeper in the pack is a mix of graupel and sun/wet grains and patches of new snow.

Mountain Weather

Mountain Weather
Mostly fine (Again!) with the chance of some clouds morning and afternoon and light to moderate South to SW winds.

Sliding Danger

Slide For Life
Taking an ice axe and crampons is the smart thing to do at this time of year. Wind scoured slopes and/or slopes that have frozen overnight can be potentially very slippery.
