Avalanche Forecast

Moderate - Uncertainty is due to limitations in the field data.

Thursday night: Clear, light west wind, alpine temperature -15 C, freezing level valley bottom.

Friday: Clear, light west wind, alpine temperature -7 C, freezing level 1500 m.

Saturday: Increasing cloud, light west wind, alpine temperature -7 C, freezing level 1400 m. 

Sunday: Cloudy, scattered flurries with trace accumulations, moderate southwest wind, alpine temperature -4 C, freezing level 1400 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 in the alpine. 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're spending time in the mountains, consider sharing your observations via the Mountain Information Network. Heightened diligence and conservative risk management is recommended at this time.

On Wednesday, temperatures reached 0 C up to 1800 m with strong solar radiation. You can expect to find either moist surface snow or crust on sun-exposed slopes. 

Snow from last week may sit on a surface hoar layer and a crust on steep solar aspects. Moderate to strong winds have redistributed snow and formed wind slabs that may remain possible to trigger in isolated areas.  

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. There is a low likelihood of triggering an avalanche on this layer, but the consequences of doing so would be high. Read more about surface hoar on our forecaster blog.

• 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.
