New snow and strong winds will be forming reactive storm slabs.
Choose low consequence, manageable terrain and enjoy the fresh pow!
In steep sheltered terrain, human triggered sluffs are running within the upper storm snow, gathering mass as they accelerate down slope.
Storm slabs will be thicker in areas lee to the SW winds. Use caution along ridge crest and convex rolls where it may be easier to trigger the storm slab.
The snow continues to add up as a series of storms pass through the region with 40cm of snow so far.
10cm by Monday morning and another 10-15cm during the day. The freezing level will rise to 1500m with an alpine high of -5. Winds at ridge top will be 30-60km/hr from the South West.
Another 15-20cm by the end of the day on Tuesday.
~40cm of storm snow covers a crust (March 11) up to 1500m on all aspects and up to tree line on solar aspects. The March 7 (surface hoar / crust) is buried ~50cm.The Feb 26 (surface hoar / crust) is down ~70cm. The Feb 15 surface hoar is down 90-130cm and decomposing.
Excellent snow quality in sheltered areas.
On Saturday and Sunday skiers were triggering size 1.0 storm slab and dry loose avalanches in steeper terrain. As the snow continues to fall, expect the size and sensitivity of the storm slab to increase.
Several natural storm slabs up to size 2.5 out of steep terrain along the Eastern end of the highway corridor the last two days.
