Salt Lake 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 is mostly LOW this morning but will most likely rise to MODERATE by this afternoon. The avalanche danger may reach CONSIDERABLE during the height of the storm which should be this evening.


CURRENT CONDITIONS

We have warm and windy conditions this morning ahead of an approaching storm. A few scattered clouds moved through overnight. Temperatures are around 35 degrees up to around 10,000 feet where they are in the upper 20s. Southerly winds have increased and are gusting into the 40s along the upper elevation ridges and speeds in the teens to around 20 at the mid elevation ridges.


RECENT ACTIVITY

Not much activity was reported from the backcountry over the last few days but not many people were out either. There was one report of a large cornice that broke off into the Wolverine Cirque on Monday. It most likely was natural but could have been human triggered. There was also a report of a small slab avalanche off peak 10420 that most likely was either snowmobile or skier triggered on a northeast aspect.


THREAT #1

WHERE PROBABILITY SIZE TREND
      Over the next 24 hours.

For today, our focus will revolve around new snow that may start to pile up and increase the avalanche danger this afternoon. It looks like most of the snow accumulation will be late this afternoon into the evening. This is most likely when the avalanche danger will peak. However, you need to start paying attention if we do see a period of heavy snowfall earlier in the day especially if the duration is a couple of hours of intense snow. Natural avalanche activity often occurs during these periods so stay clear of any runnout zones. As with any new layer of snow you need to check its behavior before getting on to steep slopes. Cracking and shooting cracks are obvious signs that it’s not stable. Perform slope cuts in safe places to try and initiate cracking. Continue to use stability tests throughout the afternoon to monitor the new snow.


MOUNTAIN WEATHER

Snowfall should start afternoon today and last through tonight. This will be a bit warmer storm with higher snow densities then the last. The rain snow line will probably start between 7000 and 8000 feet and drop but probably won’t hit the valley. Weather models show around an inch of water or more which could produce 10 inches of snow or better. Temperatures will be in the mid 40s at 8000 feet and mid 30s along the ridges. Southerly winds will continue to gust into the 40s along the more exposed locations and gradually slow and shift more westerly. Temperatures drop into the low 20s tonight.


GENERAL ANNOUNCEMENTS
