A handful of natural wet loose avalanches released with yesterday's sunny skies and warming temperatures (photo above/right). With warmer temperatures last night and hotter weather on tap today, expect the likelihood of natural and triggered wet slides to increase this morning. As sunny slopes heat up, monitor the mushiness of the surface. Once the mush gets deeper than about 4-6", triggering a sizeable sluff of wet snow on slopes approaching 40 degrees will become likely. Plan to be off of steep, sunny slopes early in the day, and don't linger beneath terrain that is getting direct sunshine.
ADDITIONAL DISCUSSION:Thursday's spring storm produced a combination of new snow and wind, and numerous natural and triggered wind slabs were reported across the forecast area on Friday. I was out in the Banner Summit zone yesterday (observation) where I didn't find any problematic wind drifts but did see evidence of recent wind. Another party nearby triggered a small wind slab. Keep an eye out for these if your travels take you into steep upper elevation terrain. Being able to identify and avoid wind slabs is a critical backcountry skill—read more in the Forecast Discussion below.
