Choose to ski mature forests and low angle terrain today. Use good group management if exposed to any avalanche terrain.
Weather Forecast
Another 10 cm of snow are forecast today with alpine temps around -7. Ridge top winds will be SW-25 gusting to 90. Snow will continue through Tuesday as a series of pacific frontal system bring waves of precipitation. Moderate to heavy precipitation is associated with the front moving through on Monday night, into Tuesday.
Snowpack Summary
A 100 cm storm slab has formed this past week. This snow overlies a weak old snow surface that was buried on Feb 10th. This weak interface is being loaded by new snow and wind, causing natural avalanches and easily triggered by skiers.
Avalanche Summary
Isolated natural avalanches were observed yesterday up to size 3.0. Natural avalanche activity is increasing this morning with moderate to strong winds alpine winds. Yesterday, several artillery controlled avalanches occurred up to size 3.0. Including Ross Peak avalanche path off Mt.Green which deposited snow onto the fan.
Confidence
Forecast snowfall amounts are uncertain
Problems
Storm Slabs
Storm Slab avalanches are the release of a cohesive layer (a slab) of new snow that breaks within new snow or on the old snow surface. Storm-slabs typically last between a few hours and few days (following snowfall). Storm-slabs that form over a persistent weak layer (surface hoar, depth hoar, or near-surface facets) may be termed Persistent Slabs or may develop into Persistent Slabs.
Wind Slabs
Wind Slab avalanches are the release of a cohesive layer of snow (a slab) formed by the wind. Wind typically transports snow from the upwind sides of terrain features and deposits snow on the downwind side. Wind slabs are often smooth and rounded and sometimes sound hollow, and can range from soft to hard. Wind slabs that form over a persistent weak layer (surface hoar, depth hoar, or near-surface facets) may be termed Persistent Slabs or may develop into Persistent Slabs.
