Moab Avalanche Advisory

Forecaster: Max Forgensi

AVALANCHE WARNING »

Dangerous avalanche conditions are occuring or are imminent. Backcountry travel in avalanche terrain is not recommended.
Notice:

The La Sal and Abajo Mountains are under an Avalanche Warning from Sunday, January 22nd at 7:30 am to Monday January 23rd at 7:30 am. Over a foot of snow has accumulated on a very weak snow pack. Combined with strong transport winds, large natural avalanches will occur on North through Southeast aspects at and above treeline. Back country travel in or under avalanche terrain is not advised.


BOTTOM LINE

Danger by aspect and elevation on slopes approaching 35° or steeper.

Danger Rose Tutorial

The BOTTOMLINEfor today will be an Avalanche Danger of HIGH at and above tree line on steep slopes greater than 30 degrees on North through SE aspects. Travel into or under avalanche terrain is not advised for at least the next 24 hours. Stay instead to lower angled terrain or meadows.


CURRENT CONDITIONS

The storm of the last 24 hours has left between 7"-12" of snow on the ground and snow water equivalent values of 1.1"-1.6" of H20. Snow densities will change dependent on elevation, expect 15% snow density down low and 10% snow density up high. Unfortunately, the wind is still transporting snow from fetch areas and depositing storm snow on leeward sides of slopes and ridges. The winds averaged from 15-40 mph with gusts up to 60 mph in the past 24 hours, starting out of the southeast and veering to its current northwesterly wind direction. Storm snow may have been deposited much lower in the starting zones due to the strong winds.

We have numerous variables which is contributing to the certain natural avalanche cycle. Once again, back country travel is NOTADVISED into or under avalanche terrain today. I would not venture into North Creek in the Abajos or into Gold Basin proper for example, where natural avalanches can hit summer roads and trails.


RECENT ACTIVITY

It will be a spectacular avalanche cycle out there. Just do so from a safe vantages.


THREAT #1

WHERE PROBABILITY SIZE TREND
      Over the next 24 hours.

A large cohesive blanket of transported storm snow lies on a very weak, faceted snow pack that will act as ball bearings. Back country travelers will hear and see whoomphs and shooting c racks from their skis and snowmobiles today. The possibility of triggering large avalanches from ridgelines is very possible. Some of these avalanches may pull back onto ridge lines, so be careful.
