Windslabs in open alpine areas near the tops of some routes. Lots of uncertainty with regards to this problem and how it is bonding to the underlying surface.
Up to 40cm of recent snow and moderate variable direction winds have created new windslabs in alpine terrain and isolated areas at treeline.

Facets near the base of the snowpack may be triggered from thin areas. On the solar aspects, full depth avalanches are possible as slopes heat up through the day. Low probability -high consequence avalanches should be in your mind.
Field observations from the Ghost are limited so please post what you are seeing on the MIN
At treeline and above a winter snowpack remains. Recent upslope storms have deposited up to 40cm of new snow in alpine areas that has been redistributed by variable moderate winds. Think about the aspect you are on/under and the time of they day you are in these areas. A cakey, drummy feeling is a good indication of new windslabs forming and being reactive to light loads such as a climber.
The weather is becoming more consistently "Spring" like with warm day time temperatures and cool mornings. Occasional snow storms will cross the region creating elevated hazards at they pass. Other weather elements that will increase the hazard are rain and or intense sun. Many areas at lower elevations have lost there snow cover but treeline and above is still fairly winter like.
