A reminder heading into the weekend that 'Low Hazard' does not mean 'No Hazard' and that isolated avalanche problems may still exist.  Check out this blog post for more information.

A weak upper trough on Sunday should result in increased cloud cover for the interior regions but is not expected to yield any precipitation.Saturday: Mainly sunny with some clouds, dry conditions, treeline temperatures around -12C, mountaintop winds NW-20km/hSunday/Monday: A mix of sun and cloud, dry conditions, treeline temperatures around -15C, mountaintop winds light to moderate NW-NE

Avalanche Summary

Reports of small natural and human-triggered loose sluffing from steep terrain features.

Snowpack Summary

The upper and mid-snowpack are generally well consolidated and layers are well bonded. In most areas, a widespread weak layer is now buried by up to 10cm of new snow but has not yet become a problem. This weak layer consists of large surface hoar (widespread in most sheltered and shaded areas at all elevations), a sun crust on open south facing slopes, facet grains (in colder areas or areas with a thinner snowpack), or a combination of any of the above. This layer is not yet a concern but is expected to become a problem in the future when we finally get more snowfall.  A facet/cust weakness near the bottom of the snowpack has recently become inactive but remains a concern. The depth of this layer makes triggering an avalanche unlikely but the consequences would be large, destructive avalanches.
