In sintesi

It is Spring time. High freezing levels and sunny skies will create unstable conditions in the afternoon when the day warms up. Start and end your day early.

Problemi valanghivi

    Probabilità
    Likely
    Dimensione
    1–1.5

    Last week's storm snow, and previous strong winds have formed isolated wind slabs at upper elevations. Some northerly winds may have loaded southerly slopes more than usual.

  • Loose Wet

    Dimensione

    Higher freezing levels and lots of solar radiation will result in loose wet avalanches out of steeper terrain.

Confidence

Moderate

  • We are uncertain about how the timing or intensity of solar radiation will affect the snowpack.

Avalanche Summary

A skier-triggered wind slab was reported on Mount Aberdeen on Saturday.

Solar input began to break down southerly aspects on Saturday. As heating continues, we expect an increase in avalanche activity over the next few days.

Snowpack Summary

North aspects hold previously wind-affected dry snow. On solar aspects, a new crust is expected to form overnight up to ridgetop. With continued daytime heating over the next few days, solar aspects and lower-elevation snowpack will weaken and break down. The lower snowpack is generally well settled.

Weather Summary

A ridge of high pressure is expected to hold through till Wednesday. Expect strong solar input during the day, leading to rising freezing levels with peak daytime heating. Freezing levels on Sunday are forecast to reach 2500 m, climbing to around 3000 m by Tuesday. Overnight recovery should be decent, with nightly lows near zero.

Terrain and Travel Advice

  • Limit exposure to steep, sun exposed slopes, especially when the solar radiation is strong.
