Logan

CONSIDERABLE: Heightened avalanche conditions exist this morning on previously drifted upper and mid elevation slopes with buried persistent weak layers. Drifting of accumulating snow from westerly winds today will cause rising avalanche danger and dangerous conditions to develop in some areas. You can find safer conditions on lower angled slopes, at lower elevations, and in sheltered terrain, but evaluate snow and terrain carefully.

-Use extra caution in the backcountry, make conservative choices, and continue to stay off and out from under steep drifted slopes.

-A backcountry skier was buried by an avalanche and killed near Fairview late Thursday, 1/18/19. Search and rescue teams from Emery and Sanpete County recovered his body Friday near Electric Lake on the Manti Skyline. Preliminary report is HERE.

-Natural avalanches were widespread across the Logan Zone late last week, but they're covered up by fresh snow now so not so obvious. Natural avalanches of note include somewhat blown-in evidence of large hard slab avalanches on many paths in the Wellsville Range, and in the Bear River Range, including big ones in Wood Camp, Tab Hollow, Logan Dry Canyon, and Castle Rock near Naomi Peak.

I could see evidence of a large hard slab avalanche in off the Beirdneau Ridge in Tab Hollow.

Wicked cold north winds wrecked the snow at upper elevations in the Bear River Range and obscured evidence of widespread natural avalanches from last weekend's storm. Stability has improved on lower elevation slopes, where cold temperatures solidified rain-saturated snow. We found nice shallow powder conditions on sunny slopes, in sheltered terrain and at lower elevations.

Cold north winds sculpted the fresh snow on Naomi Peak, scouring it off of exposed slopes and depositing it into deep stiff drifts where the wind is slowed by terrain.

The Tony Grove Snotel at 8400' reports 13º F this morning and there's 61" of total snow containing 93% of average SWE for the date. I'm reading a wind chill of -17º F, with 7º F at the 9700' CSI Logan Peak weather station, and west-southwest winds are currently averaging around 35 mph, with gusts approaching 50.

A series of weak storm systems will move over the Logan Zone through the end of the week, bringing periods of mountain snow accumulations and temperatures near seasonal normals. Today we'll see 4 to 8 inches of snow, with high temperatures at 8500' around 23º F, and 20 to 25 mph west-southwest winds with gusts around 40 mph.. Tonight, 3 to 7 inches of snow, temperatures around 25º F, and 15 to 20 mph west wind. Snow showers are likely tomorrow, with temperature around 25º F, and 15 to 20 mph west-northwest wind.

I will update this forecast Friday morning.

Now is a great time to practice companion rescue techniques with your backcountry partners. You should check out and use the new Avalanche Beacon Training Park we set up at the Franklin Basin trailhead. Special thanks to Northstars Ultimate Outdoors and USU Outdoor Program for helping us to make this possible.

The Beaver Mountain Backside is the backcountry, and it is avalanche terrain. If you cross the ski area boundary, you and your partners should carry and practice with avalanche rescue equipment.
