The cold front that has swept through the region has done a good job of locking up the snowpack and increasing stability.  The gusty winds we've been having created isolated windslabs on leeward aspects near our ridgelines.  Heads up for the new storm coming in starting tonight, with the potential for over a foot of new snow to fall on a potentially slick bed surface.

Expect avalanche danger to change rapidly going into the weekend with strong winds and heavy snowfall forecasted for Saturday and Sunday.   This new snow will be falling on a multitude of weak layers that will take multiple days to settle and strengthen.

The weekend is about to roll in with a bang weather wise.  Going into Friday morning with an overall fairly stable snowpack, but the snow accumulation is going to ramp up throughout the day today and not stop until Sunday night.  Storm totals could exceed 4 feet in areas and will be accompanied by strong winds.  Expect the avalanche danger to increase throughout Saturday and Sunday.  Significant snowfall and strong winds are two of the avalanche red flags.

Sensitive storm snow and wind slabs are resting on a layer of weak facets and a slick bed surface.  Steep terrain (over 30°) should be avoided on all aspects and elevations until this new snow has had time to settle and strengthen.

After a week of good snow and strong winds we'll be hanging out in a cold high pressure for the next 24 hours. There was a lot of reverse loading above treeline and near ridges. Areas that are normally thought of as leeward slopes may have newly formed wind slabs on them.  We're getting initial information about a snowmobile triggered avalanche in Echo bowl yesterday. No details yet... Stay safe out there!

The storm slabs and wind slabs from the President's Weekend storms are still working on stabilizing after such a big and rapid load.  Most areas are resting on a layer of weak facets and the slick rain crust sliding surface. When headed into the backcountry, use careful snowpack evaluation, cautious route-finding and conservative decision making.

Snowpack is consolidating with light powder on the surface where it is not wind affected.  Assess upper elevation ridgetops and wind affected areas greater than 35 degrees as it is highly variable.

The wind slabs and weak layers under last weekends' storm snow have strengthened significantly this week. The potential still exists to trigger an avalanche in these variable wind deposits and stubborn weak layers. Use caution in steep terrain, particularly on Southwesterly aspects.  Weather forecasts are predicting significant storm snow Saturday thru Sunday so expect avalanche danger to potentially rise with new snow and wind.
