Avalanche Forecast
Regions: Glacier.
Keep an eye on the impact of solar radiation today! Manage your overhead exposure to solar slopes and cornices accordingly.
Weather Forecast
A weak ridge over the province will maintain sunny and dry conditions today in Glacier park.
Today: Sunny with cloudy periods. Freezing level 1400m. Calm winds.
Tonight: Mainly cloudy. No snow. Freezing level at valley bottom. Calm winds.
Tuesday: A mix of sun and cloud with isolated flurries. Trace of snow. Wind SW15-35 km/h. Freezing level 1400m
Snowpack Summary
Up to 30cm of new snow sits atop a breakable crust and moist upper layers of snow up to treeline, and old wind affect in the alpine. The February facet/ crust persistent weak layer is down 80-120cm.
Avalanche Summary
No new avalanches observed yesterday. Warm temperatures with new snow overnight Friday created a moist avalanche cycle with several size 1.5-2.5 avalanches observed from steep north aspects in the alpine in the highway corridor.
Confidence
Timing or intensity of solar radiation is uncertain
Avalanche Problems
Loose Wet
Today will be the first dose of strong solar input on the recent storm snow. Expect loose snow avalanches from steep solar aspects at all elevations, especially in areas with rocky or treed features.
- Minimize exposure to steep, sun exposed slopes when the solar radiation is strong.
Aspects: East, South East, South, South West, West.
Elevations: All elevations.
Likelihood: Likely
Expected Size: 1 - 2.5
Wind Slabs
Recent storm snow and moderate southerly winds have formed wind slabs in immediate lees and near ridge crests. Use caution as you transition into more wind affected terrain.
- Be careful with wind loaded pockets, especially near ridge crests and roll-overs.
- Watch for signs of instability such as whumphing and cracking.
Aspects: North, North East, East, West, North West.
Elevations: Alpine.
Likelihood: Unlikely - Possible
Expected Size: 1 - 2.5
