Ogden Avalanche Advisory

Forecaster: Brett Kobernik

BOTTOM LINE

Danger by aspect and elevation on slopes approaching 35° or steeper.
(click HERE for tomorrow's danger rating)


Danger Rose Tutorial

The avalanche danger remains at CONSIDERABLE on any slope that has old faceted snow that has not yet avalanched. This is most pronounced in the upper elevations on west through north through east facing slopes. Human triggered avalanches are probable in these areas. If you are not able to recognize buried weak snow or not able to determine if a slope has slid you should avoid any steep terrain.


CURRENT CONDITIONS

We have mostly clear skies with ridgetop temperatures in the low 20s and light westerly winds. The snow surface consists of dense powder on northerly aspects and sun crusts on southerly. There has been some wind damage especially in the upper elevations.


RECENT ACTIVITY

No new avalanche activity was reported from the backcountry on Saturday breaking our 7 day streak of human triggered avalanches. The extent of the natural avalanche cycle in the Ogden mountains from last weekend is impressive as we continue to get into new terrain that reveals slide after slide from the cycle. (Observation) This is a double edged sword as currently the paths that have slid are mostly stable. However, these paths are now shallow and are prone to becoming weak quickly. This is already apparent with skis and poles punching through to near the ground in many locations. This could be an issue with later storms.


THREAT #1

WHERE PROBABILITY SIZE TREND
      Over the next 24 hours.

A slab collapsing the underlying weak faceted snow remains the primary concern today. As time goes on, collapsing becomes less frequent and the snowpack gets less sensitive. However, the current structure alone demands respect. There is no way that you can trust a steep slope with old weak snow that hasn't avalanched. People have teased a few of these but it's just a crap shoot. The backcountry veterans I've heard from are still holding their cards close. It appears that the mid and lower elevations have lost their energy and most of these slopes are done collapsing as the thinner slab continues to weaken.


THREAT #2

WHERE PROBABILITY SIZE TREND
      Over the next 8 hours.

Warm temperatures today may make lower elevation slopes become damp enough that people could initiate a "push-a-lanche" or be able to get snow to move by disturbing it. This is not a high priority concern but something to be aware of.


MOUNTAIN WEATHER

We'll have partly cloudy skies today with ridgetop highs up around freezing and light westerly winds. Monday we'll see cloudy skies with the chance of a flurry then a better but quick hitting storm for Tuesday which could be a 6 to 10 inch event.
