There is some uncertainty as to the type of the expected precipitation. Remember to adjust your itinerary to the changing conditions as the day progresses.
Depending on the timing of the system and the type of precipitation received, wind slabs could form over the northern aspects. These could rest on a weak layer of surface hoar, increasing their sensitivity.
No new avalanche was reported or observed.
If you go into the backcountry, thanks for sharing your observations on the Mountain Information Network (MIN).
Surface hoar was observed at all elevations and aspects, except for solar slopes. In the alpine and at treeline, this layer rests on a compacted, wind-affected surface. Below treeline, the first couple centimetres were wet on Friday, and will certainly show a crust on Saturday morning.
The core of the snowpack is well consolidated, and resting on the December 30 combo of facetted grains and crust. Facetted grains and depth hoar are developing at the base of the snowpack.
Synopsis : A low-pressure system from the Great Lakes will bring mild temperatures and precipitation. Their type and total amounts are uncertain, however.
Friday evening and night : Generally cloudy. Trace of snow or sleet. Southwest winds from 30 to 40 km/h. Minimum -2C. Freezing level at 750m.
Saturday : Cloudy. 2 to 5 cm of snow or light rain. Southwest winds from 45 to 55 km/h. Maximum 0C. Freezing level at 750m.
