In sintesi

Storm slabs may remain a problem at treeline and above this weekend. Warm temperatures and strong solar effect will add to the risk of loose wet avalanches. Stay alert to changing conditions!

Problemi valanghivi

  • Cornices

    • Alta quota
    • Limite del bosco
    • Sotto il limite del bosco
    Probabilità
    Possible
    Dimensione
    1–5
    Cornices are large and ripe these days, rising temperatures will make then weak and dangerous.
  • Storm Slabs

    • Alta quota
    • Limite del bosco
    • Sotto il limite del bosco
    Probabilità
    Possible - Likely
    Dimensione
    1–4
    Recent storm snow will take time to settle and bond, be cautious of all recently loaded  terrain
  • Loose Wet

    • Alta quota
    • Limite del bosco
    • Sotto il limite del bosco
    Probabilità
    Possible - Likely
    Dimensione
    1–2
    South facing terrain may become quite moist with daytime heating.  A small loose-wet avalanche might affect deeply buried instabilities and trigger a large destructive avalanche.

Confidence

Moderate - Timing, track, or intensity of incoming weather system is uncertain on Sunday

Weather Forecast

A weak ridge of high pressure will pass through the region today and tomorrow bringing warmer temperatures and sunny skies, then move on, followed by a cold front that will cross the coast on Sunday. On Monday a high pressure ridge will begin to establish itself to the west of the coast blocking incoming Pacific moisture for the next few days. TODAY: Freezing level rising to around 1700 m, no precipitation expected, winds are forecast to be light southwest. SATURDAY: Cloudy, freezing level around 1800 m, no precipitation expected, winds mostly from the south. SUNDAY: Freezing level lowers briefly to around 1200 m, 15 to 20 cm of snow possible, light southwest winds are forecast. MONDAY: Sunny skies with some cloudy periods, precipitation forecast for the morning, clearing up in the afternoon, freezing level climbing to 1700 m, winds from the south.

Avalanche Summary

Reported avalanche activity on Thursday was limited to small storm slabs.

Snowpack Summary

Storm totals in the northern portion of the region are between 10 and 15 cm. Slightly more snow fell in the south of the region where they received 20 to 25 cm of snow. The storm featured moderate south/southwest winds which have likely formed storm slabs at and above treeline. Below the new snow, the snowpack is strong and well-settled throughout with no notable persistent weaknesses. Cornices are huge and fragile.
