In sintesi

Stay tuned into mountain conditions as temperatures increase into the weekend. The likelihood of finding a wet avalanche is low, but can still be higher in select locations. Avoid travel on or directly below slopes where you find wet, mushy snow, fresh rollerballs, or small avalanches. Anticipate greater avalanche danger around Baker Lake and anywhere else where there was more new snow over the last three days.

    Thursday should bring a better chance of getting a real shot of sun after a few days of mixed clouds, sunbreaks, and light precipitation. Temperatures are not forecast to be especially high but will still be above freezing. Use caution navigating around steep terrain where the snow is wet and feels less stable. It's just as likely you will be able to push some wet snow down the hill as it is that you will see a natural avalanche. The higher sun angles of April mean wet most slopes can pick up additional warming from the sun.

    Look for more wet avalanches as temperatures warm in the coming days.

Avalanche Discussion

With a regime of warmer temperatures and sun also comes an increased chance of seeing renewed cornice fall, glide avalanches, or other wet-snow-shedding-from-steep-terrain events. They are unlikely and should be very limited in distribution, but you don’t want to be in the way. It’s worth noting that these types of avalanches frequently trigger a larger one on the slope below.  Minimize time spent below scary-looking cornices, glide cracks, or other unstable snow features in the terrain above you. Take extra care if heading into bigger alpine terrain as the day warms.

Observations tend to get scarce on weekdays in spring with no new snow. Precipitation amounts over the last three days varied from 1.3" at the Martin Ridge Snotel above Baker Lake, to 0.5" at Heather Meadows, to nearly nothing in the eastern half of the zone near the Cascade Crest. Actual snowfall amounts differ greatly by elevation, but in general, you can expect to find anywhere from a few inches to well over a foot of dry or moist newish snow over the crust buried in late March. Expect surface crust in the morning on most aspects that should break down by midday. Overall, the upper snowpack has become more settled and supportable after the slop-fest of the atmospheric river and then very warm temperatures between March 23rd and 27th.
