Avalanche Advisory
SABSLC
* WHAT...The Utah Avalanche Center is issuing a Special Avalanche
Advisory for all mountain regions across Utah beginning
Thursday, March 19 through Sunday, March 22, as avalanche danger
is expected to rise in the coming days.
* WHERE...The mountains of Utah and southeastern Idaho.
* WHEN...In effect from 6 AM MDT Thursday to 6 AM MDT Monday.
* IMPACTS...Record-breaking warm temperatures will rapidly
destabilize the snowpack across the state, increasing the
likelihood of widespread, spontaneous, destructive wet
avalanches. Wet avalances could occur on all aspects and at all
elevations, including places that typically stay colder this
time of year. Avoid travel on and below steep slopes, including
runout zones and terrain traps.
From: Mar 19, 2026 00:32
Until: Mar 23, 2026 12:00
Avalanche Warning
AVWSLC
* WHAT...The avalanche danger is HIGH in the backcountry today;
very dangerous avalanche conditions exist, with both natural and
human-triggered avalanches likely.
* WHERE...For the mountains of Northern Utah and Southeast Idaho,
including the Wasatch and Bear River mountain ranges.
* WHEN...In effect from 6 AM MST this morning (February 25) to 6
AM MST Thursday (February 26).
* IMPACTS...Recent heavy snow combined with wind has overloaded
slopes with poor snow structure and created widespread areas of
unstable snow. Both human-triggered and natural avalanches are
likely. People should avoid travel in avalanche terrain and stay
clear of avalanche runouts. Stay off and out from under slopes
steeper than 30 degrees.

Avalanche Advisory
SABSLC
* WHAT...The Utah Avalanche Center is warning of dangerous
avalanche conditions across all Utah mountains this weekend.
This week's heavy snowfall and strong winds overloaded
preexisting weak layers, creating a HIGH avalanche danger across
the entire state. With improving weather moving in for the
weekend, avalanche accidents are likely in the backcountry.
There have already been two tragic avalanche fatalities this
week, as well as several close calls and numerous backcountry
avalanches reported.
* WHERE...The mountains of Utah and southeast Idaho.
* WHEN...6 AM MST Friday, February 20th 2006 until Monday,
February 23rd 2006 at 6 AM MST.

backcountry and will persist through the weekend. Natural
avalanches are possible, and people are likely to trigger
avalanches on slopes steeper than 30 degrees. Dangerous and
deadly avalanches can be triggered remotely (from a distance or
from below). People leaving ski area boundaries are entering the
backcountry where the same dangerous avalanche conditions exist.
