In sintesi

After this pulse of light precipitation, we will again be into a spring daily cycle where hazard will correspond how well the crusts hold up through the day. Great skiing can still be found on steeper north aspects in the alpine.

Problemi valanghivi

  • Loose Wet

    • Alta quota
    • Limite del bosco
    • Sotto il limite del bosco
    Probabilità
    Unlikely - Possible
    Dimensione
    1–2
    10 cm of new snow may sluff easily in steep terrain and gather mass as it moves. Rain at lower elevations may trigger wet avalanches in steep terrain.

Weather Forecast

5-10 cm up high overnight and drizzle to treeline. Winds will remain light N. Skies will be cloudy overnight and Saturday for most of the region, with more broken skies to the North. Good freeze forecasted Sat. night. Skies clear for Sunday & solar affect and daytime warming will again be factors in increasing the hazard through the day.

Snowpack Summary

North facing slopes hold 20 cm of dry powder with no shears underlying, and all other aspects up to 3000 m have a melt/freeze crust on the surface. This crust is breakable in many places, but began to hold the weight of a skier (just) on steep south facing terrain at 2400 meters. Very little precipitation over the day, may see 5 cm overnight.

Avalanche Summary

One size 2.5 slid to ground on a SW aspect in Richardson's Bowl near Lake Louise ski area. It initiated just below the cliffs and went sometime in the last 24 hrs.
