The next few days will be a beautiful time to enjoy recreating in non-avalanche terrain, or in controlled areas like a ski hill.
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.
Several deep persistent slabs and several loose wet avalanches were observed from the icefields parkway Thursday.
Post avalanche observations to the MIN.
Multiple melt-freeze and sun crusts exist in the upper snowpack on all aspects and elevations except true north facing alpine slopes. Small wind slabs have formed in the alpine from moderate to strong SW winds. 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.
