Highlights

Triggering an avalanche on very steep wind-loaded slopes over 35° is possible today at middle and upper elevations. These avalanches could be up to 16 inches deep and large enough to bury you. Look for continued wind-loading and consider stiff drifts and shooting cracks as signs of unstable snow. Ride low-angle terrain to avoid any problems.

    Up to 8” of snow fell over the last 24 hours with moderate variable winds. Wind slabs up to 16 inches have formed at middle and upper elevations on many aspects and cross-loaded terrain features. The danger will be highest on very steep upper elevation slopes exposed to the wind. Look for continued drifting snow today from westerly winds that could gust in the 30s mph.  Look for shooting cracks around rocky outcrops, exposed convex rollovers, and steep gullies. Even small avalanches can knock you off your feet or sled and have high consequences if you’re above steep slopes or terrain traps.  Ride lower-angle terrain out of the wind to avoid this problem.

    Storm slab avalanches up to 8" are less likely but could still be possible today on sheltered terrain, most likely at middle elevations. New snow fell on a variety of surfaces, including melt freeze crusts on southerly aspects. Perform quick hand shear tests to assess new snow stability and continue to look for shooting cracks. Lower angle slopes will avoid this problem.

    There were obvious visual signs of recent wind effect in the Palisades high country.

Avalanche Discussion

There will be a lull in precipitation today, with an inch or two possible before more snow comes in early tomorrow morning. Winds will remain gusty at middle and upper elevations, however, so continue to look for signs of instability throughout the day as you ride. Recent avalanches, blowing snow, and drifting are all red flags that there could be unstable snow. Colder temperatures will help decrease the reactivity of any existing storm slabs. If you are unsure about conditions, perform snow pit tests or stick to lower angle slopes.
