Wet loose avalanches, even small ones, are good at grabbing skis and can push you into some undesirable obstacles or terrain traps.
Expect surface instabilities to persist tomorrow with warm temperatures and possible rain-showers at lower elevations.
Large cornices exist on most ridge crests and our nearest neighbours have reported recent cornice failures. Be aware of your overhead hazard and avoid exposure to these lurking giants.
Forecast showers and warm temperatures tomorrow will destabilize the snowpack at treeline and below. Amounts are uncertain, so be prepared to change your plans.
Small, solar triggered loose wet avalanches have been observed from steep, rocky features the past few days.
A widespread, natural avalanche cycle occurred up to size 4.0 on Mar 19-20 during the atmospheric river, filling the valley bottoms with huge debris piles in many locations. Check out pics from this exceptional avalanche cycle in the MIN Reports.
Spring conditions exist throughout the park. We expect minimal overnight crust recovery again tonight, which means daytime heating or rain tomorrow will permeate deeper into the snowpack.
A thick rain crust from the March atmospheric river sits 20-50cm below the surface.
Below treeline the surface varies from isothermal sticky snow to refrozen tree bombs and huge debris fields from the massive avalanche cycle in March.
A Pacific low brings unsettled weather this weekend. Expect mainly overcast skies and light snow or rain, depending on elevation.
