The sustained winds from Monday night into Tuesday morning changed the snow conditions in the Alpine. Observers reported pockets of wind slab and scoured ridgelines. While traveling today look for areas that have had recent loading and avoid stiff snow in steep terrain. Watch for cracking and listen for hollow sounds that could indicate the shallow wind slabs may be reactive.
The Turnagain Pass area received an inch of snow yesterday and more is forecasted for today and tonight. Pay attention to changing conditions and expect avalanche danger to increase as we load up the weak surface snow that formed during the period of high pressure and low danger.
What has changed or is changing? These should be the questions in the next few days. Look for Red Flags: recent avalanches, cracking, whumfing, recent snowfall and signs of recent wind. These signs of instability indicate heightened avalanche danger and the need for cautious travel behavior.
Good travel habits, such as exposing one person at a time, watching your partners, grouping up in safe zones and having an escape route planned are, as always, key ways to minimize risk.
