Forecast for the Salt Lake Area Mountains

Issued by Mark Staples on
Wednesday morning, April 14, 2021

Today the avalanche danger is MODERATE at upper elevations as slabs of wind drifted snow form later today from south winds. Also, watch for sluffing of the new snow and possibly some soft slab avalanches of new snow. The danger at mid and lower elevations is LOW.

Special Announcements

Sunday, April 18th will be the 163rd avalanche forecast and the last one for the 2020/2021 season. For the rest of the month of April, we will provide updates on the snow and weather anytime it snows which is hopefully a lot. We will also continue to post observations.

Weather and Snow

This morning, it's windier in many valley locations than in the mountains where winds are blowing 10-20 mph gusting 30 mph from the east-southeast. Temperatures are generally in the mid 20s F. As of 5 a.m. only 1 inch of snow has fallen.

Today, a slow-moving storm will bring 5-9 inches of snow with more tonight and tomorrow. Some cold air will move into the area this afternoon and help keep temperatures cool. High temperatures today should be in the upper 20s to low 30s F. Winds will shift direction and blow from the south 10-20 mph. Gusts at the highest elevations will reach 55 mph.

Total snow accumulations by Friday morning should be 8-14 inches of snow (0.8-1.2 inches of water).

Recent Avalanches

No avalanches were reported yesterday. The snowpack remained frozen and hard.

As always, find all of our observations and recent avalanches HERE.

Description

As new snow accumulates and is transported by south winds, expect to find fresh slabs of wind drifted snow. These wind slabs could be a foot deep by later this afternoon, and they will be the main avalanche issue to look for and avoid.

Description

Instabilities in the new snow depend on how much falls, how it sticks to the old, hard, frozen snow surface, and how the new snow bonds to itself. By the end of the day, sluffs in the new snow will be possible but should be shallow.

I don't expect any soft slab avalanches in the new snow; HOWEVER, watch for cracking in the new snow, and any sign that it is becoming a soft, cohesive slab. A dramatic increase in snowfall rates with snow falling 1-2 inches per hour will also be a sign that soft slab avalanches in the new snow may happen.
