Lo esencial

The avalanche danger will rise to MODERATE on mid and upper elevation slopes facing east through south and west with natural and human-triggered wet, loose avalanches possible.

On isolated mid and upper elevation slopes facing west through north and east there is a MODERATE danger for triggering soft slabs failing on a buried persistent weak layer.

The cold, dry snow from last week was slowly introduced to warming over the weekend: it was first touched by sunshine on Saturday and slightly warmer temperatures and cloudy skies on Sunday. Therefore, today's strong sunshine and temperatures rising above freezing won't shock the snow surface, but there will be some avalanches involving wet, loose snow on aspects facing east through south and west. Wet rollerballs and loose sluffs are indications the snow surface is warming and that it's time to move to more northerly aspects.

The January/February drought resulted in weak, faceted snow along many snow surfaces and it was covered by the 6-12" of snow and wind-drifting from last week. Avalanches failing on this persistent weak layer are still possible on slopes facing northwest/north/east, but require need a denser, more-cohesive slab (i.e. wind-drifted) to avalanche. Cracking and collapsing are signs this structure exists. Avalanches failing on this PWL (persistent weak layer) can be triggered remotely (from a distance).

Before committing to a steeper slope on these W/N/E aspects, evaluate the snowpack and avoid slopes that have the structure of a stronger, denser slab on top of the buried PWL as shown in this photo.

Recent Activity

Other than minor wet-loose sluffing, no backcountry avalanches were reported from Sunday.

Snow and Weather

Currently: Skies are clear with temperatures in the upper 20's F. Winds are from the west and light, with gusts in the teens along the most-exposed upper ridgelines.

For today, temperatures into the mid and upper 30's F at low and mid-elevations and right around freezing at the upper elevations, although today's clear skies and strong sunshine will likely make it feel much warmer. Winds will remain light with gusts in the 20's mph along the highest exposed ridges and summits.

Temperatures will warm through midweek with a trough possible by the end of the week.
