Update 6:10 am: New snow and wind loading have formed reactive storm slabs, especially on north through east-facing slopes.

Stick to conservative terrain sheltered from the wind.

Moderate

• We are uncertain about forecast snowfall amounts.
• We are uncertain due to the timing of the incoming weather system.

On Monday, the region saw a widespread natural avalanche cycle up to size 3, which likely occurred during the storm.

Avalanche danger may spike on Wednesday afternoon with new snow and strong winds.

Up to 60 cm of new storm snow has blanketed the region. This sits on a variety of surfaces, including old wind slab on all aspects, facets, and exposed crust. Expect the potential for a poor bond at the storm snow interface.

The early February crust/facet layer is down approximately 100 cm.

Another widespread crust and facet layer from late January is buried 120 to 160 cm deep.

The mid and lower snowpack is well settled and strong.

• Avoid avalanche terrain during periods of heavy loading from new snow, wind, or rain.
• Strong wind is building wind slabs farther downslope than usual.
• Back off if you encounter whumpfing, hollow sounds, or shooting cracks.
• Start with conservative terrain and watch for signs of instability.
