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 all sunny, steep terrain and on steep wind-loaded slopes at upper and exposed middle elevations. Small human triggered wet loose avalanches are possible today due to unusually warm temperatures and direct sunshine. Skiers and riders can also trigger older 1-4 ft. deep wind slabs that overlie crusts and weak faceted snow. In shady, non-wind loaded terrain at lower elevations, the avalanche danger is LOW. ...MORE

Smoky & Boulder Mountains

Bottom Line: The avalanche danger is MODERATE in all sunny, steep terrain and on steep wind-loaded slopes at upper elevations. Small human triggered wet loose avalanches are possible today due to unusually warm temperatures and direct sunshine. Skiers and riders can also trigger isolated new wind slabs or lingering old 1-2 ft. deep wind slabs that overlie crusts and weak faceted snow. In shady, non-wind loaded terrain at lower and middle elevations, the avalanche danger is LOW. ...MORE

Mountain Weather Summary

Mountain temperatures hit the lower 30's to mid 40's F yesterday under partly to mostly cloudy skies. Winds were light to moderate out of the NW with a trace of snow or rain falling in a few locations. Last night temps struggled to fall below freezing in many mountain locations due to low cloud cover. This morning temps range from 20's F in the valleys to mid/upper 30's in the mountains.

Today, winds will continue to be light to moderate out of the NW, but temperatures will be the big player. We'll see highs in the 40's F with a few locations possibly reaching 50 F under partly cloudy skies.

Tomorrow expect even warmer temperatures, clear skies, and light winds. Our next chance for snow looks to be Tuesday night.
