Turnagain Pass Avalanche Forecast
The avalanche danger is CONSIDERABLE in the Alpine where triggering a slab avalanche is likely. Below 2500′ the danger is MODERATE. If there is any snow left triggering a wet loose avalanche will be possible and being in the runout of snow-covered slopes above should still be avoided today.
The Friends of the CNFAIC have two scholarships dedicated to avalanche education. The funds generated to make these possible are in celebration of Rob Hammel and Amy Downing, their love and passion for the mountains, and to help others stay safe. We encourage you to read each one and apply if you fit the need, or pass along to someone who could benefit. Applications due on Dec 1st.
Rob Hammel Scholarship Fund €“ For recreational users and professional avalanche workers.
Amy Downing Scholarship Fund €“ For recreational users.

Yesterday was much like the previous few days will an additional inch of water falling in the advisory area. Rain/snow line was between 2500′ and 3000′. In the Alpine there has been significant snow load. Today triggering an avalanche in this elevation band is likely and avalanches could be large. There has been almost no visibility to see what has happened above the rain/snow line over the past 4 days and we have limited data on the overall snowpack structure. We do know that there were conditions for surface hoar and a melt-freeze crust before the storm. If you do venture into the mountains this is a day to proceed with caution and choose terrain carefully. Be on the lookout for signs of instability: recent avalanches, shooting cracks, and whumpfing.
Water totals at the mid-elevation snow stations for this storm cycle from Saturday through Tuesday:
If there is any snow left at treeline (2500′ and below) triggering a wet loose avalanche in the saturated snowpack is also possible before the temperatures cool down later in the day.

Yesterday: Rain and snow throughout the day. Rain/snow line was between 2500′ and 3000′. An inch of water fell in advisory area. Winds were easterly 15-25 mph with gusts into the 40s. Temperatures were in the 40Fs at sea level and in the high 20Fs on Sunburst at 3800′.
Today: Light showers transitioning from rain to snow are forecast for today as cooler air moves into the area. Temperatures should slowly cool into evening starting in the mid 30Fs and dropping into the mid 20Fs. Chance of snow showers overnight. Winds will be easterly 5-15 mph with gusts in the 20s.
Tomorrow: Partly sunny with temperatures in the high 20Fs to low 30Fs. Light SW winds. There is some discussion about the next storm moving into the area over the weekend but timing, temperatures, and precipitation type are still uncertain.
