One of the new big avalanches seen at Turnagain Pass was on Pete’s North. The Southwest face pulled out full depth sometime Thursday afternoon to Friday morning.
As long as we have warm temperatures, this kind of avalanche is possible. It’s worth noting that these large destructive avalanches are happening across a huge region in southcentral Alaska. Valdez is currently under seige with the Richardson highway closed (second photo below). Check out this observation for more photos and video from the Summit Lake region.
Sun exposure today may have enough power to tip the balance on south facing slopes in the afternoon.

At the bottom of our snowpack we still have weak snow from November that is making full depth avalanches a reality. This is most obvious from 3000 feet elevation and below where rain-on-snow has created an especially difficult problem. Even higher up, above the rain line, it’s been snowing for more than a week. The snowpack at higher elevations is finally getting deep, but stability is in question until we have evidence to suggest it won’t slide. Remember, before the storm that dumped many feet of snow on these slopes we had numerous natural and remote human triggered avalanches. Now that the problem is buried deeper it may be harder to trigger but the consequences of resulting avalanches will be significantly worse.
The hose of pacific moisture that’s been hitting us for the past week has shifted back to the west for the time being. Unseasonably warm temperatures continue today, some of the weather stations are currently at the highest we’ve seen all month. Freezing level is expected to reach 4400 feet elevation again today.
Partly sunny skies are forecasted today. Look for fog in the valleys. Southeast to East wind blowing 42-61 mph at the ridgetops.

Status of riding areas across the Chugach NF is managed by the Glacier and Seward Ranger Districts, not avalanche center staff. Riding area information is posted as a public service to our users and updated based on snow depth and snow density to prevent resource damage at trailhead locations.
