Expect small, loose wet avalanches on steep, sunny slopes today.

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

An icon showing 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.

Likelihood

Possible

Expected Size

1 - 2.5

Wind Slabs

An icon showing 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.

Likelihood

Unlikely - Possible

Expected Size

1 - 2
