Highlights

It will be possible to trigger wet snow avalanches today as temperatures rise and intense April sun continues to affect snow surfaces. Hard, slick crusts may make travel difficult where previously sun affected snow remains frozen. Make localized assessments of hazards and conditions, and time your day appropriately to minimize your exposure.

    We will see warm temperatures again today, well above freezing at all elevations. Increasing SW winds may prolong or help deter excessive warming today on certain slopes. However, direct April sun can still warm snow surfaces significantly. Wet, sticky snow, increasing boot penetration, and rollerballs are all signs that indicate wet loose avalanches are becoming more likely. Areas near radiators, such as rock features and cliff bands, are especially susceptible to increased warming and are often areas where these avalanches can be triggered. Plan your day to be off of steep slopes by the time the snow gets too wet to minimize your exposure today.

Avalanche Discussion

Dozens of naturally occurring wet loose slides were observed up to size D2 yesterday on all aspects and at all elevations. The isolated exceptions are the highest elevation N and NW slopes that were heavily affected by strong N winds throughout yesterday morning. 

Strong winds out of the southwest may help to deter warming, but direct April sun is intense, and temperatures will be well above freezing at all elevations. Surfaces affected by sun and temperature will be hard and slick until warmed enough, which may create difficult and dangerous travel conditions. Sharps, such as crampons and an ice axe, may be necessary. 

A storm will blow into the region tonight, dropping temperatures, locking up snow surfaces, and bringing up to a foot of new snow at high elevations by end of day tomorrow. Avalanche danger will rise accordingly.
