Summary
Weather Forecast
A weak ridge over the province will maintain sunny and dry conditions today in Glacier park.
Today: Sunny with cloudy periods. Alp high -7*C. FZL1300m. Calm winds.
Wed: Cloudy with sunny periods, trace snow, Alp high -8*C, light/gusting mod SW winds
Thurs: Cloudy with sunny periods, Alp high -9*C, light W winds
Snowpack Summary
N'ly aspects are holding cold, dry snow with isolated wind slabs in immediate lee areas. Meanwhile, the March sun has enough punch to quickly moisten surface snow on S'ly aspects well into the alpine, causing moist/wet conditions. This also creates a breakable crust once the sun leaves the slope.
Avalanche Summary
Several loose, wet avalanches up to sz 2 were observed from steep, solar aspects yesterday. Most avalanches were small, averaging sz 1-1.5.
Confidence
Problems
Loose Wet
Today's strong solar input on S'ly slopes will increase hazard during the warmest part of the day. 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.

Expected Size
Wind Slabs
Isolated wind slabs can be found in immediate lee areas and near ridge crests. Watch for surface stiffness and cracking under your board(s) in the alpine.
- Be careful with wind loaded pockets, especially near ridge crests and roll-overs.
Aspects: North, North East, East, West, North West.
Elevations: Alpine.
