North Rockies

Warm temperatures and strong sun will increase the likelihood of falling cornices and wet loose avalanches.

On Thursday, a few natural and rider-triggered triggered size 1-2 wind slabs were reported on southerly aspects in the alpine.

NOTE: Observations in this region are currently very limited.

On the surface, up to 20 cm of recent snow exists on northerly aspects in the alpine. Solar aspects and lower elevations will sport a crust or moist snow.

Below this, a 5 to 25 cm variable strength crust from last week's rain event is present. This is capping a moist upper snowpack.

A persistent weak layer from early March, 40 to 80 cm deep, most likely exists as surface hoar on sheltered north and east aspects in the alpine. Its distribution is variable, and there have been no substantial reports of recent avalanches, but it should still be considered when evaluating slopes.

• Avoid travelling on slopes below cornices.
• The more the snowpack warms up and weakens, the more conservative your terrain selection should be.
• Be careful as you transition into wind-affected terrain.
