Yesterday wind loading was observed in Turnagain Pass with Northeast ridgetop winds blowing 15-25 mph for most of the day. These fresh slabs could be tender and may awaken older deeper wind slabs (1-3’ thick) that formed over Valentine’s Day weekend. Be aware of this problem on slopes steeper than 35°, especially near rocks and on unsupported terrain features. Over the last few days observations have shown good bonding since Monday when two separate human triggered avalanches occurred in the Goldpan area of Turnagain Pass. Avalanching has not been widespread, but this set-up needs to be considered, especially later in the day with increased sun exposure.
Loose snow avalanches: There is the potential for wet loose avalanches on steep southerly slopes and dry loose avalanches on steep northerly slopes. Remember these will release at your feet but may gain momentum and catch you from behind as you travel downhill. Evaluate terrain where taking a fall could have high consequences.
Two small (D1) avalanches on ‘Juniors’ West aspect of Seatte Ridge, apear to be skier triggered. No official report of timing of these avalanches, but likely occured on Monday.
Cornices have released naturally over the last few days and many have triggered fresh wind slabs. When approaching a ridgeline it can be challenging to recognize a safe distance. Be very skeptical of other tracks along ridgetops and don’t be tempted to walk to the edge for a better look. Cornices are notorious for breaking much further back than expected and if one releases it will be very large. Natural cornice fall activity should also be anticipated with warming from the sun, thus avoid spending time below cornices.

Glide Cracks cover many steep slopes between 1000’ to 2500’ and continue to release without warming. Over the last few days several have released and many have significantly widened. Be extra diligent about planning your route to avoid these unpredictable hazards. Minimize any time directly underneath and do not re-group below them.

Yesterday was partly sunny becoming mostly cloudy by mid afternoon. Temperatures warmed to the mid 30’s F along the highway, but remained cooler, low 20’s F at higher elevations. Moderate Northeast winds 15-25mph blew all day and just started subsiding this morning.
Partly sunny skies are anticipated again today with Easterly ridgetop wind decreasing to 10-15mph. Day time temperatures with sun exposure may reach the mid 30’s F again today, but shaded area will likely remain in the 20’sF.
A similar pattern is expected tonight into tomorrow, but with increased cloud cover.
