Avalanche Forecast

High - Confidence is due to a stable weather pattern with little change expected.

Saturday night: Clearing overnight, light southwest wind, alpine temperature -12 C, freezing level valley bottom. 

Sunday: Cloudy, up to 5 cm of snow, light to moderate southwest wind, alpine temperature -5 C, freezing level 1300 m. 

Monday: Mostly cloudy, 5-15 cm of snow, light southwest wind, alpine temperature -5 C, freezing level 1300 m. 

Tuesday: Mostly cloudy, 5-10 cm, light variable wind, alpine temperature -9 C, freezing level 400 m. 

Over the past several days, avalanche activity has been reported as natural loose wet and dry avalanches to size 1.5 and 2 running on steep, sun exposed slopes. There have also been reports of cornices failing in the alpine on northerly aspects to size 2.5.

There are currently no professional operations reporting in the region. If you decide to travel in the backcountry, consider sharing your observations via the Mountain Information Network (MIN) to supplement our data stream as operators are shutting down. A conservative mindset and margins are recommended at this time.

With snow on the way, Sunday's surface conditions will comprise the next interface. Recent reports indicate that conditions are highly variable with a mix of sun crusts, moist snow, hard wind slabs, and soft faceted snow. Observers have noted that surface hoar may be forming on sheltered, shady slopes. These conditions will be important to track across aspects and elevations if you're spending time in the mountains on Sunday.

Cornices are large, looming, and weakening with warm temperatures and strong solar radiation.

A weak layer of surface hoar buried at the end of February may be found 50-100 cm deep, except in the northern tip of the region. Sheltered north, northeast, and east facing slopes near treeline are the most likely locations to find this layer. Avalanche activity on this layer was last reported March 6th. 

• Back off slopes as the surface becomes moist or wet with rising temperatures.
• Pay attention to cornices and give them a wide berth when traveling on or below ridges.
• Small avalanches can have serious consequences in extreme terrain. Carefully evaluate your line for wind slab hazard before you commit to it.
• Make observations and assess conditions continually as you travel.
