Avalanche Advisory
Advisory: Salt Lake Area Mountains Issued by Brett Kobernik for Tuesday - February 11, 2014 - 6:39am
bottom line

VERY DANGEROUS AVALANCHE CONDITIONS REMAIN. HUMAN TRIGGERED AVALANCHES ARE LIKELY AGAIN TODAY. Overall there is a CONSIDERABLE avalanche danger but the danger is still HIGH on upper elevation north through east facing slopes. Avoid being on or below slopes of 30 degrees and steeper.




special announcement

UDOT WILL BE CONDUCTING AVALANCHE MITIGATION USING EXPLOSIVES IN BIG COTTONWOOD THIS MORNING. A BACKCOUNTRY CLOSURE IS IN EFFECT FOR TERRAIN FROM STAIRS GULCH THROUGH KESSLER AND MILL D SOUTH. THERE WILL BE A BRIEF ROAD CLOSURE AS WELL.

ALTA SKI LIFTS WILL BE CONDUCTING AVALANCHE MITIGATION WITH EXPLOSIVES IN THE PATSY MARLEY - WOLVERINE AREA. TERRAIN BETWEEN GRIZZLY GULCH AND CATHERINE'S PASS WILL BE CLOSED THIS MORNING UNTIL THEY ARE DONE.

current conditions

Temperatures dropped into the teens in many locations overnight with partly cloudy skies. Westerly winds slowed since yesterday with light to moderate speeds right now. Riding conditions are fairly decent.

recent activity

A few shallow wind slabs were triggered by skiers and snowboarders in Grizzly Gulch on Monday but the most significant avalanche was in West Monitor along the Park City Ridgeline. Skiers dropped a cornice onto the slope which rolled most of the way down before the entire slope collapsed and avalanched big. The fracture line was up to 6 feet deep and the avalanche ran well into the flats below. DETAILS Good visibility allowed for viewing of many avalanches that released during the storm. Check the AVALANCHE LIST for details.

Large avalanches breaking into older weak layers is the most dangerous issue today. It's not time to mess with the big slopes. Let the snow settle. Attention Canyoneers: The out of bounds terrain in MacDonalds, Dutches, Squaretop, etc. have similar traits to West Monitor where the cornice had to meander to near the bottom of the slope before it found the sweet spot and went big.

Wind slabs that formed on Monday will be less sensitive but still may be touchy. Avoid the lee sides of ridges where the wind has been depositing snow. Keep in mind that wind slabs can form on almost any aspect due to terrain features and localized variations in the wind.

weather

We'll see partly cloudy skies with more clouds during the day. Ridgetop temperatures will get into the low 20s and west wind speeds should remain light to moderate. Another warm storm is going to roll through starting Wednesday but looks like it will mostly favor areas north of the Central Wasatch. We still should see some snow but probably nothing like the last storm depending on how far south the system drifts. We are anticipating quite warm temperatures following the storm.
