All melt no freeze... and a large avalanche cycle are expected to continue for the foreseeable future.
Cornices will become increasingly unstable as the warm weather continues, and will likely act as triggers for the deep persistent slab problem.
Warming temperatures will continue to produce wet loose avalanches.
widespread natural large to very large loose wet and slab avalanche activity observed on the Icefields patrol on Saturday. Reports of large loose wet cycle in the Maligne Rd area from Friday afternoon.
Post avalanche observations to the MIN.
As alpine temperatures reach double digits, surface crusts are losing cohesion and amalgamating into moist snow. A crust/facet PWL lingers in the mid-pack in many areas at tree line and above. The main concern is the depth hoar and basal facets at the base of the snowpack.
A dramatic rise in daytime temperatures and strong solar radiation is forecasted for the next several days. There is also forecasted to be warm air trapped at higher elevations overnight, so don't let cool early mornings at valley bottom mislead you into thinking there has been a good overnight freeze.
