In sintesi

Put a wide margin between yourself and cornices, as they are particularly sensitive at the moment. Additionally, watch out for a weather system that will move into the region starting Tuesday and elevating the hazard.

Problemi valanghivi

  • Loose Wet

    • Alta quota
    • Limite del bosco
    • Sotto il limite del bosco
    Probabilità
    Possible
    Dimensione
    1–2
    This problem will be active on solar exposures receiving daytime heating. Cloudy skies will mitigate the severity of the wet spring cycle to a certain extent.
  • Deep Persistent Slabs

    • Alta quota
    • Limite del bosco
    • Sotto il limite del bosco
    Probabilità
    Unlikely - Possible
    Dimensione
    1–3
    Inputs to watch out for are intense solar radiation. Although there is low likelihood that this avalanche problem will occur, the consequences are high if it does.

Weather Forecast

A system is going to track through the forecast region starting Tuesday afternoon. It is calling for warm temps and a moderate amount of precip. This COULD amount to rain at valley bottoms, hence the considerable danger rating on Tuesday below treeline.

Snowpack Summary

HST settling and a surface crust will exist in the am and break down over the day on all aspects up to to 2200ms, higher on S and W aspects. Cornices seem to be more sensitive to the temperature fluctuations especially on the solar aspects and have been seen to trigger slabs below both in the storm snow and the deeper persistent layers.

Avalanche Summary

No avalanches were observed or reported today.

Confidence

Timing, track, or intensity of incoming weather system is uncertain on Wednesday
