👉 CAUTION - BULLETIN VALID FOR THURSDAY, MARCH 28 AND FRIDAY, MARCH 29 👈
The snowpack will continue to become saturated over the next few days and increasingly susceptible to triggering. It is best to avoid avalanche terrain until the snowpack refreezes.
Warm temperatures and rain could produce small avalanches of loose wet snow. The risk is greater on steep slopes. The more water-logged the snow (slush), the greater the avalanche risk.
Warm temperatures and precipitation in the form of rain could trigger wet slabs in places where a slab (storm or wind) existed. Every day of warm weather increases the risk of avalanches.
An accident involving snowmobilers occurred on Tuesday, March 26, near La Martre, just outside our forecast area. For more details, please consult the MIN report.
If you head into the backcountry, thanks for sharing your observations on the Mountain Information Network (MIN).
The top 25 to 30 cm of the snowpack is moist or wet. The rainfall still to come will help to make the upper part of the snowpack isothermal, allowing water to percolate down to the underlying crust.
There is a crust of 4 cm thick down 40 cm from the surface. Beneath this crust, there is 20 cm of dry snow resting on a layer of ice that extends to the base of the snowpack.
Last weekend's wind loaded the south and southeast slopes with snow in the alpine and at treeline.
Synopsis: Warm temperatures and rainfall will continue for the next few days. Freezing levels will remain above 2,000m until Saturday morning. Some models see snow showers for the Easter vacation.
