Highlights

A spring storm will create dangerous avalanche conditions in wind-loaded terrain as the day progresses. Steer around steep slopes that appear freshly loaded and activly look for signs of instability as you travel. Triggering wet avalanches will be possible near or below the snow line. 

07:30 Update: Updated text to reflect the overnight snow totals better.

    Avalanches will be easiest to trigger in wind-loaded terrain on Tuesday. Look for these slabs to be bigger and more reactive as you climb into windy, exposed terrain above 6000 f, particularly during the later morning or afternoon hours. Slabs will form over a variety of wet snow surfaces and crusts, so slab sensitivity may vary from slope to slope. Use can use small test slopes or snowpack tests to help you pinpoint instability.

    Look for these slabs on the downwind sides of ridges, below cornices, or on steep convexities in exposed terrain. Watch for blowing snow, dunes, sharp cornices, and snow pillows. Wind slabs will often feel stiff or may even keep you on the surface in more exposed terrain. Pump the brakes if you notice shooting cracks under your feet or skis. 

    You can minimize your exposure by avoiding steep, wind-loaded start zones and features. Blowing snow and poor visibility will make it harder to know exactly where you are and what's above you, so include wider safety margins or buffer zones in your travel plans on Tuesday.

    Blowing snow, fresh drifts, sharp cornices, and rime all point towards wind loading along this ridgeline.

    Near the snow line and below, keep wet avalanche concerns on your radar. Over the last 24 hours, we have seen nearly 1 inch of rain at elevations below 6500 ft. The snowpack may be wet and punchy in many areas, so pushing a wet avalanche could be easier than you think on steep, unsupported slopes. Any wet loose avalanche could gouge and grow large on bigger slopes or in canyon terrain. Predicting when and where you’ll trigger a wet avalanche is tricky. So the best mitigation strategy is avoidance, especially if you find yourself sinking past your boot-tops in wet, sloppy snow.

Avalanche Discussion

As of 07:00 AM, the storm has brought 2-4 inches of new snow, with another .7 -.8 inches of precipitation forecast during the daytime hours. So far, Timberline and the western sides of the mountain have picked up the most new snow, with less further east around Meadows and Tilly Jane. If the forecasted water numbers verify, look for rising avalanche danger during the daytime hours. We'll likely start the day with moderate-like danger, but with additional accumulations and strong winds, we should push into considerable territory in wind-loaded terrain above 6000 ft as new snow piles up. 

Avalanche forecasting in the spring is complicated, especially during stormy periods like this. Observations tend to be more sparse and frequent temperature fluctuations can easily create overlapping avalanche problems. With fewer on-the-ground observations, there’s usually a higher degree of uncertainty in our avalanche forecast product. During these active periods, consider building in a wider safety margin to account for the unknowns. It's a good reason to dig around more and approach steep terrain with more caution.
