Lynnea Baker,
5-10 cm more snow is expected Saturday night before switching back predominant to the SW flow.
As freezing levels rise Monday and Tuesday watch for pin wheeling and surface snow becoming moist. Hazard will increase with temperatures.
Summary
Weather Forecast
Tonight: Flurries, accumulating 5-10 cm.
Sun: Mix of sun and cloud with isolated flurries. ALP high -2. Light gusting moderate SW winds. Freezing levels 1600m.
Mon: Cloudy with isolated wet flurries. ALP high +4. Light gusting strong SW winds. FL 2000m.
Tues: Cloudy with isolated wet flurries. ALP high of 0. Moderate gusting extreme SW winds. FL 1800m
Snowpack Summary
10 cm of soft snow found on polar aspects and in sheltered areas on Rowe Peak. Below 1900m snow surface is a 3cm breakable melt freeze crust. Variable N-E winds have redistributed snow into isolated windslabs in ALP. This overlies a rain crust to mountain top. Well consolidated mid and lower snowpack. HS 250-300 cm near the continental divide.
Avalanche Summary
Few loose dry avalanches to size 1 with solar input Thursday and Friday. No new avalanches reported on Saturday. Please report any observations to the Mountain Information Network we really appreciate the information as neighboring operations are shutting down for the season.
Confidence
Timing, track, or intensity of incoming weather system is uncertain
Problems
Wind Slabs
Our predominant SW winds for the area will be back Sunday, 15-25 cm will be redistributed into windslabs in lees. Keep an eye out for lingering pockets of small of reverse loaded windslabs from the last week of variable N-E winds.
- Keep an eye out for reverse loading created by an upslope storm.
- Use caution in lee areas. Recent wind loading have created wind slabs.
Aspects: All aspects.
Elevations: Alpine, Treeline.

Loose Wet
As freezing levels rise Monday, Tuesday watch for signs surface snow is becoming moist. Exercise caution in steep slopes, confined areas and terrain traps.
- Use extra caution on slopes if the snow is moist or wet.
Aspects: East, South East, South, South West, West.
Elevations: Below Treeline.

Expected Size
Cornices
As temperatures and freezing levels rise Monday and Tuesday cornices will weaken with day time heating. Pay attention to over head hazard and minimize time below cornices.
- Give cornices a wide berth when travelling on or below ridges.
- Stay well back from cornices.
Aspects: All aspects.
Elevations: Alpine.
