Weather Forecast

A high pressure ridge over the southern interior continues to prevent any significant moisture. Cloud bringing flurries and light rain can be expected. Temperatures have risen and will continue to do so into Wednesday. Forecast models indicate freezing levels to hover between 1500m today rising to 1700m by Tuesday.

Snowpack Summary

Firm crust below treeline at the surface. In open areas, wind has created variable conditions ranging from wind deposited powder, to breakable crust. Pockets of touchy wind slab up to 20cm deep exist near ridge line. Recently buried surface hoar with variable distribution is down ~15cm. This sits just above the Feb 14 crust which is ~5-10cm thick.

Avalanche Summary

No new natural avalanches have been observed yesterday.

Confidence

Freezing levels are uncertain

Avalanche Problems

Wind Slabs

Strong winds have formed touchy slabs. Small pockets have been reactive to skiers at or near ridge crests. Winds have come from all directions over the last week so lee slopes include all aspects.
Use caution in lee areas in the alpine. Recent wind loading have created wind slabs.Be cautious as you transition into wind affected terrain.

Aspects: All aspects.

Elevations: Alpine.

Likelihood: Unlikely - Possible

Expected Size: 1 - 2
