In sintesi

The avalanche danger is LOW and avalanche conditions are generally safe. Watch for isolated pockets of fresh wind drifts on all aspects at the mid and upper elevations as well as wet, loose avalanches on aspects facing east/south/west as well as low and mid-elevation northerly aspects.

The glide avalanche in Broads Fork on Wednesday is a good reminder this avalanche problem will be a threat for the rest of the spring. Liquid water can move through and underneath the snow and around underlying rocks in ways we can't observe. The timing of a glide avalanche releasing is generally unpredictable. What is predictable is where these avalanches happen which is typically in Broads Fork and Stairs Gulch, and other places with smooth rock slabs underneath the snow. There is often a large crack in the snow that extends to the ground visible before these avalanches happen. The main strategy to avoid this problem is to avoid being under any slope with a visible glide crack, and I would personally avoid being under any terrain with large rock slabs under the snow.

Recent Activity

No backcountry avalanches were reported from Thursday, but an avalanche that likely ran on Wednesday was reported by guide and avalanche educator Erme Catino. This was in Red Pine on a west aspect just below 10,000'.

Our Week in Review - where we highlight significant snow and avalanche activity from the prior week - has been published.

Snow and Weather

A dry cold front moved through the region overnight, dropping temperatures into the teens and elevating west/northwest wind speeds, especially at the upper elevations. At 10,000' winds are averaging in the teens with gusts in the 30's mph, and at 11,000' winds are averaging in the 40's, with gusts in the 60's mph, including an 80 mph gust at midnight.

Fortunately, wind speeds are forecasted to diminish today, to more reasonable speeds averaging in the teens with gusts in the 20's and 30's mph. Temperatures will rebound and rise above freezing, generally in the 30's and possibly low 40's F. Skies will be clear with strong sunshine.

For this upcoming weekend, skies will be clear with moderate winds from the northwest. Temperatures will be warmer on Saturday, with another windy and dry cold front Saturday night, with much cooler temperatures forecasted for Sunday. There is a possibility of a return to a more active storm pattern setting up by mid-week.

On Thursday my partner and I were finding cold dry snow on northerly aspects at the mid and upper elevations, with early stages of a corn cycle in progress on east, south, and west aspects. Travel conditions in the alpine zones are quite good right now, although strong winds overnight have likely reduced the chances for finding soft snow as well as eroding many snow surfaces.
