Warmth remains the main driver of avalanche hazard as we shift into a more spring like pattern. Minimize your exposure to large slopes if the snowpack is becoming moist or wet.

Avalanche Summary
No new activity to report from Tuesday. On Monday warm temps led to a natural size 2 wet slab failure that ran on a steep NE facing feature near 2200m.
Snowpack Summary
The region experienced it's second overnight temperature recovery in a row Tuesday night. This time the night brought freezing temperatures that much closer to the valley floor; an overnight low of -2c was recorded at 850m. This resulted in the formation of a surface crust that was already reported as being supportive Monday. This crusts sits on top of 3 to 10cm of moist snow which overlies the March 24th crust that is up to 20cm thick. Below this crust there is 15 to 60cm of snow that is likely still moist from the previous rain event. This moist snow is reportedly bonding well to the mid-March crust/facet complex. The mid and lower snowpack are strong and well settled.
