Good skiing is still being found on higher polar aspects where last weeks heat and rain didn't effect it. This is the season to start early (Headlamps) and finish early to maximize easy travel and limit your exposure to sun baked slopes.
Wind slabs in the recent storm snow should be expected at open treeline features and above. Evaluate the bond with the underlying snowpack which is highly variable. There is currently a lot of uncertainty with the characteristics of this interface.
The persistent layer down 1m has been active due to recent snow loads. It also appears to be sensitive to heat.
Shallow snowpack areas are an area of special concern, especially with intense solar radiation and/or daytime heating.
Great evidence of this problem avalanching is easy to find along the spray road right now.
No new avalanches observed or reported, But evidence is easily visible as you drive through the valleys.
Dry snow remains on polar aspects at higher elevations, with recently formed wind slabs in lee and cross-loaded terrain. Solar aspects are primarily crusty in the morning and becoming moist with daytime heating and radiation. Travel at lower elevations is fast and easy in the mornings on a thick melt-freeze crust from the rain last week. Forecasters continue to track persistent weaknesses down anywhere from 40 to 100cm on polar aspects. These weaknesses are highly variable in nature and travelers should take the time to dig down and evaluate the snowpack frequently. Also, the lingering deep persistent slab problem is still alive and well. The deep weak layer of facets and depth hoar have become quite active in the increased heat, and this is expected to continue, with large destructive avalanches possible.
Solar radiation has a big influence on stability at this time of year. Stability will quickly deteriorate on solar aspects as temperatures warm up. These decreases will be most apparent on steep solar aspects, especially in thin rocky terrain. Early starts and finishes that avoid the heat of the day are key. Also pay close attention to what aspect you are on or under, and be mindful of cornices.
Sunday evening there may be some flurries 4cm. Night time low's will be -9. 45-65km Southwest winds. Monday will have a mix of sun and cloud, no precip expected, and winds continue to gust in to the 60 km range from the Southwest.
