Points saillants

Avalanche danger relates directly to daytime warming and solar radiation. Although cloudy skies are forecasted tomorrow, its still wise to get an early start and early finish.

    With reduced solar inputs and a cooling temperature trend forecasted this week, the loose wet problem will be less of a concern. Any unforseen increases in temps/solar or significant rain could quickly increase the likelihood of this problem.

Weather Forecast

Light precipitation expected for Tuesday. At higher elevations snow values may reach 5-10cm and at lower elevations a mix of snow and rain is expected. Temperatures will stay near zero. Minimal solar input is expected, however localized solar input (un-forecasted) could elevate the danger rating. Temperatures will continue to cool into Wednesday.

Snowpack Summary

Overnight cooling has developed a melt freeze crust on all aspects and elevations except for hight north facing terrain. This crust has been deteriorating with daytime warming. Dry snow is still found on high north aspects. Many areas exhibit a cohesive midpack over the basal facets, while other thin areas have weak facets to the ground.

Avalanche Summary

No new avalanches observed or reported.
