👉 CAUTION - BULLETIN VALID FOR TUESDAY MARCH 26 AND WEDNESDAY MARCH 27 👈
Tuesday will be a great day to enjoy the snow in the mountains before the heavy rainfall forecast for Wednesday. Be sure to take the time to read the bulletin, several avalanche problems are present.
The wind slabs rest on a thin solar crust at a depth of around 50 cm, on which facet grains have developed. This configuration makes the wind slabs still sensitive to triggering.
Be particularly careful near couloir start zones and alpine bowls, under convexities and in cross-loaded areas of the alpine and treeline.
Solar radiation, warm temperatures and rain could produce small avalanches of loose wet snow.
Warm temperatures and precipitation in the form of rain could trigger wet slabs in places where a wind slab problems existed.
Several size 1 to 2 avalanches were reported on south-facing slopes, including a size 2 avalanche accidentally triggered by a skier on a south-facing slope with a crown around 50 cm thick.
If you head into the backcountry, thanks for sharing your observations on the Mountain Information Network (MIN).
We find great spatial variability in the mountains due to the strong to extreme winds that have accompanied recent storms.
At mid-mountain, in areas sheltered from the wind, 50 to 60 cm of snow rests on a thin friable crust. Beneath this crust, a further 20 cm or so of snow covered the very firm crust of March 10. Solar aspect have been affected by the sun.
The middle of the snowpack is very well consolidated down to the ground. The average snow depth is around 130-160 cm.
Synopsis: A ridge of high pressure stationed directly over the Chic-Chocs will give us another beautiful day in the mountains on Tuesday. Things will start to turn nasty from Tuesday evening, with freezing rain turning to rain.
Monday evening and night: Clear. Light southerly wind, 15 to 20 km/h. Low -10.
Tuesday: Sunny. Wind southeast, 30 to 40 km/h. Maximum +5. Mountain inversion. 10 mm of freezing rain expected overnight.
Wednesday: Rain. 10 mm. Strong south-westerly wind, 60 to 80 km/h. High +7. Mountain inversion. Freezing level at 3,000 m.
Thursday: Cloudy. Moderate southwesterly wind, 20 to 40 km/h. High +8. Freezing level at 2,000 m.
