Choose a conservative route. The spring snowpack has been very active, with large avalanches failing naturally.
Summary
Confidence
Moderate - Timing or intensity of solar radiation is uncertain on Tuesday
Weather Forecast
Cloud, moderate to strong NW winds and a few snow showers may linger on Tuesday morning, before a ridge brings dry and very warm weather again for the remainder of the week. Freezing levels of around 1700 m on Tuesday are expected to climb above 3000 m by Wednesday.
Avalanche Summary
A cycle of large natural avalanches has been reported from the north Elk Valley, which occurred on Friday and Saturday. At least one of these appears to be a persistent slab, and all were likely to have been triggered by warming. A size 2.5 storm slab also released in steep rocky terrain in the south-east on Friday. With skyrocketing temperatures predicted this week, I would expect further large/deep natural avalanche activity.
Snowpack Summary
Large cornices overhang alpine slopes. Glide cracks have opened up on several slopes and herald more glide avalanches to come. Variable surface crusts exist. Low elevation and thin snowpack areas have become isothermal. Deeply buried weak layers in the mid snowpack and near the ground appear to have woken up in some areas with prolonged warming (see avalanche discussion).
