Recent strong winds have created pockets of reactive wind slab, primarily in north-facing terrain.

• The snowpack structure is well understood.

A rider-triggered size 1.5 wind slab occurred Tuesday on north-facing terrain. No other recent avalanches have been observed.

Observations are limited, so be sure to post yours to the MIN if you get out!

Strong southerly winds on Wednesday night largely stripped new snow from windward slopes and loaded leeward terrain in exposed terrain.

A widespread early-February melt-freeze crust, buried by roughly 20 cm of recent snow, is present at treeline but absent in the alpine.

The January 26th crust is 30 to 70 cm deep. Surface hoar may persist above, on north through east, wind-sheltered slopes. The snow overlying this layer is generally well-settled and thick, making triggering unlikely.

Weak facets or depth hoar exist at the bottom of the snowpack. And could be a concern in shallow areas.

• Avoid areas where the snow feels stiff and/or slabby.
• Choose low-angled, sheltered terrain where new snow hasn't been wind-affected.
• Avoid shallow, rocky areas where the snowpack transitions from thick to thin.
