Avalanche Warning  AVALANCHE WARNING   Avalanche Warning
CENTENNIAL MOUNTAINS/ISLAND PARK

Areas Affected:
Caribou Range - Big Hole Mountains
Effective: Fri, 3/1 7:26pm Updated: Sat, 3/2 1:05pm Urgency: Unknown
Expires: Sun, 3/3 12:00am Severity: Unknown Certainty: Unknown

 
Details:
AVWPIH

* WHAT...Avalanche warning. The avalanche danger is expected to
increase to High overnight. Intense snowfall rates and
increasing winds will make natural avalanches likely and human-
triggered avalanches very likely.

* WHERE...Northwest Wyoming including Togwotee Pass, the Teton,
Snake River, Salt River, and Wyoming Ranges. Mountainous areas
of southeast Idaho including the Webster, Preuss, Caribou, Snake
River and Big Hole Ranges.

* WHEN...In effect until Midnight Sunday morning.

* IMPACTS...Heavy snowfall and strong winds will create dangerous
avalanche conditions. Roof slides, and separate non-avalanche
hazards like tree wells and snow immersion, are also likely.

Information:
Very dangerous avalanche conditions will develop tonight. The
combination of intense snowfall and wind will create wind slabs
that will be large and easy to trigger. Avalanche conditions will
be most dangerous on slopes with windblown snow, but triggering a
slide breaking on steep, sheltered slopes is also possible. Avoid
terrain exposed to steeper slopes overhead, and avoid wind-loaded
terrain. Human-triggered and natural avalanches are very likely.
Avalanches may involve deeper, weak layers of snow and produce a
larger avalanche than expected. Avalanches could run onto low
angle terrain, hitting paths, roads or groomed snowmobile trails.

more detailed information.

Similar avalanche danger may exist at locations outside the
coverage area of this or any avalanche center.

avalanche far above and run into lower-angled terrain. Go to
