Avalanche Advisory
Advisory: Ogden Area Mountains Issued by Brett Kobernik for Wednesday - February 10, 2016 - 7:10am
bottom line

The avalanche danger starts out mostly LOW this morning but will rise to MODERATE as the daytime heating starts. Carefully monitor the sunny slopes you are on and what is above you watching for the snow to become damp and sloppy.

current conditions

Temperatures are mild in the high country this morning with readings at 9500 feet in the mid to upper 30s. This is the first night we've seen overnight temperatures above freezing. Wind speeds are light from the west or southwest. Riding conditions have deteriorated on many aspects due to sun and wind but folks are still finding enjoyable snow.

recent activity

It appears that wet activity on Tuesday was not as active as the previous days.

Wet activity can be hard to forecast. The key is to just pay attention during the day and be ready to move off of slopes as they become too wet. Here are some other things to consider today. Despite warm overnight temperatures, radiational cooling should have frozen the snow surface up again. Although, warm temperatures overnight may lead to the wet activity getting an earlier start today. However, we may see some thin clouds that would counteract the heating some and lessen the wet activity. Also, usually the wet activity is most active during the first few days of the heating event. But, as temperatures remain warm overnight for a number of days, we can see percolation of the melt water loosen up deeper weak layers. So, there is a big push-pull affect that you should keep in mind but most importantly, choose terrain where you can exit easily if things become more unstable more quickly than you anticipated.

Here's a great video from Bruce who was looking at southerly facing terrain on Tuesday: Bruce checking southerly slopes for wet activity

  • A few hard wind slabs could still be triggered in upper elevation terrain and along ridge lines.
  • In isolated places, you might still be able to trigger a slide on the buried surface hoar layer in the Ogden area mountains, probably on mid to upper elevation, north to northeasterly facing slopes.
  • The icy, hard crusts create a Slide-for-Life potential early in the morning when they are still frozen.
  • Only in isolated places could you still trigger a slide breaking on facets near the ground in the Ogden area mountains. I would still be suspect of any slope that slid during the December avalanche cycle - steep, northwest and northeasterly facing, upper elevation slopes. Very low probability, but with large consequences.
  • There have been reports of weak structure in the Ogden area snowpack on mid elevation, northwesterly facing slopes.
weather

Someone definitely flipped the switch on what seemed like an unending series of storms. We are seeing the exact opposite now with a significant ridge of high pressure that will stay with us at least through the weekend. Temperatures will again be warm today with 9500 foot highs in the low 40s. West southwest wind should be light to moderate in speed. We'll probably see some high clouds that may not be much more than fairly thin. Thursday looks similar with perhaps a few more clouds and slightly warmer temperatures.
