Wind slabs are found in lee features and on bigger, planar slopes there may be some cross loading.
Day time warming is a major consideration for avalanche hazard right now. If the temperatures spike, the moderate rating could easily jump to considerable with wet loose avalanches being the additional concern. Keep those thermometers handy.

The Feb crust has been the main bed surface for many avalanches this winter. Slopes and features that have not slid should be treated cautiously or just avoided. Dig and look.
Facets near the base of the snowpack may be triggered from thin areas and this season there are lots of thin areas. Don't try to outsmart the snowpack and stick to conservative terrain until we get into a good spring diurnal cycle.
No new avalanches observed or reported today.
Below treeline is basically in full spring with a steadily shrinking, near isothermal snowpack. At about 2000m the snow still feels wintery with several layers being apparent. All solar aspects have a 10cm surface crust with a very slight dusting of recent, dry snow. Starting at treeline, the polar aspects still have dry snow. There has been some wind transport near ridges in the last 48 hours that's built new windslabs in immediate lee areas. Cornices are continuing to grow as these winds continue.
Beautiful day in store for Saturday. Some thin cloud will hopefully limit the solar input and buy some time before the snow starts to soften. Overnight low of -6, with a mid morning warm up to above zero. Daytime high of +3. No snow is expected in the next few days. Light winds all day, except for some gusts near alpine ridges.
