Lo esencial

Avalanches large enough to bury or injure a rider will be unlikely on Saturday. In the afternoon, it will be possible to trigger small wet avalanches on steep slopes receiving direct sunlight. If you notice slushy snow penetrating above your boot top, consider shadier terrain or slopes less than 30 degrees.

    We are in the midst of a pretty ideal melt-freeze cycle currently, with cold clear nights allowing for a solid freeze of the upper snow surface, and warm (but not overly hot) daytime temperatures softening the surface enough for pleasant corn riding on slopes that have received enough sun. Saturday is looking to be more of the same, with very similar weather to Friday on the forecast. For reference, on Friday I found good, stable corn skiing on an upper elevation south-facing slope around 1pm. Although I did not see any signs of wet loose activity in this instance, I would have expected that an hour or so later could have been a different story. 

    Timing can be critical during these spring diurnal cycles. As the day heats up through Saturday afternoon, the likelihood for triggering a small wet loose avalanche will increase. Although any slide would likely be small, it is important to remember that a small slide knocking you off your feet can have high consequence when on an exposed slope with terrain traps such as cliffs. Monitor the snow surface throughout the day for signs of rollerballing or slushy surface snow. If you are uncertain about the snow's stability, seek shadier or less steep slopes.

Avalanche Discussion

There is a bit of a variety of snow surface conditions out there currently, with isolated pockets of preserved dry snow lingering on shaded, sheltered upper elevation slopes. Solar slopes are getting nice and soft from the Spring sun, while relatively cooler temps are resulting in open shadier slopes staying quite firm. I would anticipate all lower elevation slopes to be very firm through the first half of the morning on Saturday, with long sliding falls being the primary hazard during this time. Keep all of this in mind as you plan your terrain and timing for the day.
