Sunshine and warm temperatures on Tuesday could lead to slightly higher danger ratings in the afternoon. If the snow is getting moist or wet then move to cooler, shadier slopes.

Avalanche Summary
No new avalanches have been reported recently. It may still be possible to trigger old pockets of wind slabs or loose snow sluffs from steep sun-exposed slopes, especially if conditions remain warm and sunny.
Snowpack Summary
Variable snow surface consists of wind-affected snow or wind-scoured crusts in exposed alpine areas, moist snow or sun crust on sun-exposed slopes, or 5-10cm of dry snow overlying an old crust in shady and sheltered areas. At higher elevations, ongoing winds may be continuing to build thin wind slabs in leeward features. Lower elevations are undergoing daily springtime melt-freeze cycles. The most prominent feature in the snowpack is the thick late-February crust, down 5-20 cm. This crust is supportive all the way to ridge crest and is effectively "capping" the snowpack, keeping riders from stressing any deeper weak layers. There are still weak layers below this crust that we'll continue to monitor, but for now these layers are dormant. We would likely need significant warming and/or heavy loading to re-activate them.
