Avalanche Canada
A deep persistent weak layer remains in the snowpack, avoid thin rocky areas where triggering this layer will be more likely.
Prepare for challenging travel on a thick crust.

Avalanche Summary
On Sunday a size 1 wind slab was reported near the summit of Mt Rogers. No other avalanches have been observed or reported in the Park for several days.
Snowpack Summary
Expect a robust surface crust on all aspects below 1700m making for difficult travel. Above this elevation north facing slopes still hold up to 15cm of dry snow. A weak layer formed on March 9th is down ~30cm and the Feb 3rd persistent weak layer remains a concern at 80-140cm deep. The lower snowpack is well settled and strong.
Weather Summary
An unsettled atmosphere will bring periods of light precipitation over the next few days and light to moderate winds.
Tues: Cloudy, possible flurries late in the day, alpine low -10 °C, light W winds, FZL 1600m.
Wed: Sun and cloud with flurries - trace of new snow, alpine low -11 °C moderate S winds, FZL 1600m.
Thurs: Cloudy with snow up to 7cm, alpine low -7 °C, light winds, FZL 1900m.
Terrain and Travel Advice
- When a thick, melt-freeze surface crust is present, avalanche activity is unlikely.
- Conditions may have improved, but be mindful that deep instabilities are still present.
- Remember that the snowpack will be significantly different at higher elevations than lower down.
Problems
Persistent Slabs
Two persistent weak layers are the main concern in the snowpack. One down ~30cm which, if triggered, could step down to the deeper layer (80-140cm) producing destructive slab avalanches. When there is a supportive crust on the surface, slab avalanches are less of a concern.
Aspects: All aspects.
Elevations: All elevations.
