Ridgetop winds have been moderate speed out of the SW for the past 24 hours drifting very minor amounts of old snow. Blowing snow amounts may increase slightly with increasing wind speeds today. However, new wind slabs of any significant size are not expected to exist in the backcountry today. Cloud cover combined with some mixing out of the air temperature inversion is expected to reduce warming at the mid and upper elevations today by a few degrees. Lesser amounts of snow surface melt on SE-S-SW aspects is expected to occur today compared to what has occurred over the past three days.
Despite the expected good snowpack stability in the backcountry today, expose only one person at a time to steep slopes and do not group up in low angle areas with connected steeper terrain above (avalanche runout zones). Avoid traveling near cornice edges or stopping below cornice features as large sections of cornice collapse can occur. Large horizontal cracks exist in isolated areas due to snowpack creep. These deep cracks can be covered by thin weak snow bridges presenting an additional fall hazard. See the recent observations section below for more info.
