Observations yesterday point toward weak snow at the ground in the upper elevations (above 3,000’) that show significant potential to propagate. We are unclear how widespread these basal facets are across the forecast zone and with no other red flags (recent avalanches, whumphing or shooting cracks) reported in nearly a week, our snowpack is sending us a bit of a mixed message this weekend. It’s the kind of avalanche problem (persistent slab) that may not present itself until a skier finds the sweet spot and triggers an avalanche, potentially after several tracks on the slope. So, if the plan is to push into bigger, steeper, above treeline terrain today, it’ll be worth digging a quick pit to see if you can find loose, faceted snow at the very bottom of the snowpack. Look for snow with the consistency of a handful of sugar and if found, recognize that as your weak interface.
The snow quality right now is arguably the best it’s been in over a year so no doubt the usual zones in Turnagain will be crowded. Keep other adjacent groups in mind as you are moving through the mountains today and maintain good backcountry etiquette. Wear and know how to use your rescue gear, expose one person at a time on a slope, discuss potential consequences if a slope does slide and don’t ski on top of other parties.
8-10″ of new snow made for great skiing at 3,000′ on Sunburst ridge yesterday. Keep in mind that If northerly winds kick up today earlier than expected, we’ll see shallow, sensitive wind slabs on slopes with a southerly tilt given the substantial amount of loose snow available for transport.
Yesterday was again marked by mild weather throughout the forecast zone. Temperatures were comfortable in the 20’s, winds very light out of the East and just a few intermittent snow showers throughout the day not really amounting to much accumulation.
Today we can expect more of the same with morning fog eroding to clearing skies throughout the day and no new precipitation. The winds are expected to increase throughout the day and into this evening from the North but are not expected to be much above 20mph at ridgetops. Temperatures will be in the low 20’s F at ridgetops and the high 20’s to low 30’s F at 1,000′. Prepare for a couple more days of high pressure before our next shot of unsettled weather has the potential to move into the region next Tuesday/ Wednesday.

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.
