In sintesi

The avalanche danger is MODERATE on upper elevation slopes facing west to north and east for wind-drifted snow avalanches. Here it is possible to trigger a hard or soft wind slab 6-18 inches deep and up to 100 feet wide. Human-triggered avalanches are possible. If, for any reason, the sun comes through the clouds and the temperatures are warmer than expected and the snow surface becomes wet, we should be thinking of wet snow avalanche issues. This includes north-facing terrain.

Pockets of wind-drifted snow 6-18" thick can be found on northerly-facing slopes at the upper elevations. Strong southerly winds overnight and into this morning could keep old wind slabs sensitive to the weight of riders as well as develop some fresh new wind drifts.

Hot tip: if you're on a ridgeline toss a snowball into the slope; if it lands in powder and sinks in, there is no wind slab; if it lands on a hard surface breaking the snowball there is probably a wind slab, and you should find another way into the slope. Avoid the wind-drifted snow, and you'll avoid the avalanche problem today.

Recent Activity

No new avalanches were reported yesterday in the Ogden area.

Snow and Weather

This morning, mountain temperatures range from 15-35°F. Winds are southwest at 15-30 mph, gusting into the 40s across the upper elevations. The skies are mostly cloudy as a large cut-off low digs south along the Pacific Coast. This cut-off low will usher in southerly winds, warming temperatures, and thin high to mid-elevation clouds. Temperatures will climb into the low to mid-30s °F.

The good news is the winds have already peaked, and they should die off almost entirely later today as the storm moves south (as shown by the graph below). The bad news is this storm will produce no precipitation for us, and our next hope for new snow will be Tuesday.

Snow surfaces have taken a beating from the sun and wind. However, one can still find soft, settled powder in sheltered locations.
