Points saillants

The avalanche danger will rise to MODERATE on slopes facing east, south, and west - including low and mid-elevation northerly slopes - where you can expect human-triggered and natural avalanches involving wet snow as the snow surface warms. Upper-elevation northerly slopes have a LOW danger, but in the southern end of the range, the danger may approach MODERATE where it is possible to trigger an avalanche failing on a buried persistent weak layer 1-3 feet deep.

With warm temperatures and plenty of sunshine we can expect the snow surface to melt and become unstable with daytime heating. Remember, if you're seeing roller balls or the snow becomes unsupportable, it's time to head to cooler aspects or seek lower-angled terrain. Wet-snow avalanches can run very far, especially in confined gully features. Today is not the day to be in steep sunny terrain in the late afternoon.

These layers move towards dormancy, and the likelihood slowly decreases each day. However, the snowpack is so variable right now. This means that in one place, you can have a deep and strong snowpack while in another place, the snowpack is shallow.

For now, my advice would be to probe (check depth) and dig down in the snowpack before committing to any steep north-facing terrain and make sure the slope has not avalanched before. Steep rocky terrain or slopes with a shallow snowpack would also be very suspect for harboring weaker snow.

Recent Activity

The usual round of wet loose avalanches happened again yesterday with daytime heating and direct sunlight.

Observations and Avalanches

Snow and Weather

Current mountain temperatures are strongly inverted, with trailheads at 24 °F while upper elevation peaks range from 35- 40 °F. The wind is out of the east-northeast and hardly blows with speeds of 5-10 mph. Temperatures this morning are about 2-3 degrees warmer than yesterday.

Today, we will have plenty of sunshine as high pressure continues. The wind will have an east component as a closed low spins to our south. However, wind speeds will remain calm, with ridgetop wind in the 5-10 mph range. Mountain temperatures will climb into the upper 40s to low 50s °F today.

There will be a shorter window of supportable snow today as we have a shallow overnight refreeze of the snowpack.
