Avalanche Summary
No new avalanches were reported in this region on Thursday. However, there are currently no professional observers submitting daily observations. Please submit your observations to the MIN. Photos of avalanches or current conditions are particularly useful.
Snowpack Summary
As temperatures cool, we will enter a diurnal cycle during which the hazard will be low in the mornings, if there was a strong overnight freeze, and elevate throughout the day depending on warming and solar radiation. Hazard ratings are for the peak hazard expected during each day.

Problems
Wind Slabs
New snow and moderate winds from a variety of directions may form small wind slabs reactive to human triggers.
- Pay attention to changing conditions with elevation/aspect.
- Be careful with wind loaded pockets, especially near ridge crests and roll-overs.
- Use small slopes without consequence to test the bond of the new snow.
Aspects: All aspects.
Elevations: Alpine, Treeline.
Likelihood
Expected Size
Loose Wet
Any appearance of the strong April sun can initiate a loose wet avalanche cycle. The likelihood of loose wet avalanches increases as temperatures warm through the day and/or if the sun comes out for a prolonged period of time.
- Avoid exposure to terrain traps where the consequences of a small avalanche could be serious.
- A moist/wet snow surface, pinwheeling and natural avalanches all indicate a weakening snowpack.
Aspects: All aspects.
Elevations: Alpine, Treeline.
