Kernpunkte

Strong winds and snow will lead to further slab development overnight. This may push the danger rating to CONSIDERABLE if more snow falls than is expected.

Lawinenprobleme

  • Cornices

    • Hochgebirge
    • Waldgrenze
    • Unterhalb der Waldgrenze
    Wahrscheinlichkeit
    Unlikely - Possible
    Größe
    1–5
    Cornices are large and sagging. Recent cornice failures have been triggering slabs on the underlying slopes. Be aware of overhead exposure especially during times of intense solar radiation or rain.

  • Storm Slabs

    • Hochgebirge
    • Waldgrenze
    • Unterhalb der Waldgrenze
    Wahrscheinlichkeit
    Possible
    Größe
    1–4
    Storm slabs between 5 and 40cm thick are present in lee and cross-loaded features at higher elevations. Additional slab formation is expected overnight Wednesday. Be cautious in areas where these slabs sit on a smooth crust layer.

  • Loose Wet

    • Hochgebirge
    • Waldgrenze
    • Unterhalb der Waldgrenze
    Wahrscheinlichkeit
    Unlikely - Possible
    Größe
    1–5
    As crusts melt with solar radiation, daytime heating and/or rain, wet avalanches are occurring. Be especially cautious in areas that have had little or no overnight freeze. Many slides are failing on the ground and involve the entire snowpack.

Confidence

Fair - Timing, track, or intensity of incoming weather is uncertain

Weather Forecast

A short, but intense burst of precipitation is expected Wednesday evening possibly bringing rain to lower elevations. Thursday will see a mix of sun and cloud, slightly cooler temperatures and moderate NW winds.

Avalanche Summary

Nothing new today, but observations were limited.

Snowpack Summary

Storm slabs up to 40cm thick are found in lee and cross-loaded features in alpine and open areas at treeline. Crusts are found on all aspects at all elevations, except for true North aspects. These crusts are of widely varying thickness and strength, but generally provide very fast travel conditions while frozen.
