Avalanche Danger Rose: this graphic represents an avalanche forecaster's idea of how the avalanche danger exists across the topography in a given region. It is not a map...it is an idea. Picture it as a cone-shaped mountain viewed from above, built of three elevation bands; the outer ring represents low elevations, the middle ring represents middle elevations, and the innermost circle represents high elevations. Each elevation band is divided into sectors that represent the slope aspect (N-NE-E-SE-S-SW-W-NW). Each sector\'s color represents the avalanche danger rating assigned that day (see Avalanche Danger Scale).

In this example, the Avalanche Danger Rose depicts an avalanche danger rating of considerable on all high elevation aspects and on north to west-facing mid elevations; all other sectors possess moderate avalanche danger. The illustration depicts the spatial distribution of this forecast across a landscape.

Avalanche Problem Rose: this graphic represents an avalanche forecaster's idea of the distribution of a particular avalanche problem across the topography in a given region. Picture it as a cone-shaped mountain viewed from above, built of three elevation bands; the outer ring represents low elevations, the middle ring represents middle elevations, and the innermost circle represents high elevations. Each elevation band is divided into sectors that represent the slope aspect (N-NE-E-SE-S-SW-W-NW). Sectors colored grey are thought to have the identified avalanche problem while white sectors do not.

In this example, the Avalanche Problem Rose indicates that a particular avalanche concern exists on all high elevation aspects and on north to west-facing mid elevations and that this concern is far less likely to be encountered on other aspects and elevations.
X Chance of Avalanches: This graphic depicts how likely you are to trigger avalanches or encounter natural avalanches while traveling on avalanche prone slopes. Unlikely means that few avalanches could be triggered in avalanche terrain and natural avalanches are not expected. The chance of triggering or observing avalanches increases as we move up the scale. Certain means that humans will be able to trigger avalanches on many slopes, and natural avalanches should be expected.
X Size of Avalanches: This graphic depicts the potential size and destructive force of expected avalanches. Small avalanches are not large enough to bury humans and are relatively harmless unless they carry people over cliffs or through trees or rocks. Moving up the scale, avalanches become large enough to bury, injure, or kill people, large enough to bury or destroy vehicles and break a few trees, and large enough to destroy railway cars, buildings, or a substantial amount of forest. Historic avalanches are massive events capable of destroying villages and gouging or altering the landscape.
X

LOW: Generally safe avalanche conditions. Watch for unstable snow on isolated terrain features.

X

MODERATE: Heightened avalanche conditions on specific terrain features. Evaluate snow and terrain carefully; identify features of concern.

X

CONSIDERABLE: Dangerous avalanche conditions. Careful snowpack evaluation, cautious route-finding and conservative decision-making essential.

X

HIGH: Very dangerous avalanche conditions. Travel in avalanche terrain is not recommended.

X

EXTREME: Avoid all avalanche terrain.

Current Advisory Summary

All Zones | Sawtooth Mountains | Smoky & Boulder Mountains | Wood River Valley | Soldier Mountains

 

Sawtooth Mountains

Bottom Line: The avalanche danger is MODERATE in steep, recently wind-loaded terrain. Yesterday, moderate to strong N-NW winds moved snow onto leeward slopes, forming isolated small wind slabs at upper elevations. The fresh wind slabs buried slick crusts and weak, faceted snow and may be sensitive to triggering. In non-wind loaded terrain, the danger is LOW. ...MORE

Mountain Weather Summary

Yesterday, partly cloudy skies gave way to mostly clear conditions, mountain temperatures reached the teens and 20's F, and moderate to strong N/NW winds blew on the ridgetops. Overnight, temperatures dropped to the single digits and teens beneath clear skies while N/NW winds generally diminished to light to moderate levels.

High pressure takes hold today, bringing clear skies for the foreseeable future. Temperatures climb to the 20's F while light to moderate NW winds blow on the ridgetops. Tonight, a temperature inversion will likely keep upper elevations in the teens F, skies remain clear, and light to moderate NW winds continue.

Temperatures climb about 10 degrees F each of the next couple days, running 10-15 degrees above normal by Friday.
