    Probabilidad
    Likely
    Tamaño
    1–5
    Large cornices at upper elevations will be de-stabilized by high freezing levels and incoming rain. Cornice falls may trigger large wet loose avalanches and potentially trigger slabs from upper north facing start zones.

Weather Forecast

A moist Pacific frontal system will bring moderate to heavy rain to the region overnight Thursday, continuing light to moderate through Friday. Freezing levels will gradually fall to 1600m on Saturday as precipitation tapers off with up to 6 cm of snow at upper elevations.

Avalanche Summary

One report of a sz 2.5 cornice initiated avalanche which triggered a slab to ground on the fan.

Snowpack Summary

The upper snowpack is now moist on all aspects as high as 2300m in elevation with reports of isothermal conditions as high as 2000m. The surface on north aspects is now moist due to warm overnight temperatures the past two nights.
