Points saillants

Areas of CONSIDERABLE avalanche danger exist in steep terrain. Any new snow avalanche may step down into older snow layering, particularly on steep northwest to easterly facing aspects. Conservative decision making remains essential today.

New snow soft slab avalanches 1-2' deep can still be triggered today in steep terrain of all aspects and elevations. These new snow avalanches will be reactive to ski cuts and cornice drops. If traveling into the higher elevations, soft slabs of wind blown snow are to be expected in the lee terrain. Shooting cracks are good indicators of instability. Isolated natural new snow avalanches will also be possible in the steepest terrain today as well.

Any new snow avalanche may step down into older snow layering, creating a larger and more destructive avalanche. Last weekend's Extreme avalanche danger led to natural avalanches on all aspects and elevations, with rain down to 8000' or so. The snowpack has slowly started to adjust but you can still trigger avalanches on these weak layers today. I would continue to avoid steep avalanche prone terrain today.

Recent Activity

Avalanche control work triggered a large avalanche at Sundance yesterday 3-4' deep and 350' wide on a steep northeast facing slope at 7500'.

An observer near Aspen Grove watched a natural avalanche cascading out of the NE chute of Elk Point yesterday.

Snow and Weather

Skies are clear. Mountain temperatures are in the low 20s. Winds are light from the west.

For today, we'll have partly cloudy skies with temperatures rising to the mid to upper 20s. Winds will start to increase from the southwest this afternoon.

Most areas picked up another trace overnight, pushing storm totals to 16"/1.5" SWE. Coverage is amazing with 80-100" in the upper elevations of the Provo mountains.

Riding conditions were a bit upside down yesterday, but overnight settlement will probably improve conditions for today.
