Yesterday brought the warmest temperatures we have seen for quite some time on the mountains. Overnight temperatures did not fall below freezing at elevation for very long.

We have received nearly a foot of new snow at upper mountain elevations in the last week.

The last 4 days direct sunlight accompanied by the diurnal fluctuation (day time warming do to the sun). Created quite a few point release size 1 slides along the Face of Mt Roberts and on Mt Juneau.

Larger slides can develope in open, steeper locations with longer slide paths.

Look to see snow falling off of trees, rocks, and cornices as well. This has the ability to start point release avalanches.

In steep open areas these relatively small slides have the ability to gather quite a bit of mass and momentum.

Look to see quite a few size 1 slides as the sun holds throughout the day. In areas with windloading and in pockets of additional mass larger class 2 slides are possible.

With the presence of Human Triggers backcountry danger is questionably high in areas, especially during the later part of the day after the sun has had time to affect the snowpack.

Be sure to make good decisions and remember danger levels grow during the later heat of the day as the sun becomes more overhead and has more effect.

Remember, Partner, Probe, Avalanche Tranceiver, Shovel.
Dont leave home without them!!!
