The Avy Rose shows the forecasted danger by elevation and aspect.

It adds more detail about where you are likely to find the dangers mentioned in the forecast. The inner circle shows upper elevations (mountain top), the second circle is middle elevations, and the outer circle represents lower elevations.

Think of the Rose as a birds-eye view of a mountain, looking down from above. The rose allows our forecasters to visually show you which parts of the mountain they are most concerned about.

Avalanche Activity

The highway avalanche hazard is CONSIDERABLE.


We received 1 ½ inches of water in the last 36 hours, with the freezing line fluctuating between sea level and mid mountain. This translated into slush at sea level, 6 inches of heavy snow at 1500 feet, and probably 18 inches of snow in the upper mountains. Also, moderate wind has loaded western aspects. Observations have been limited, though some avalanche activity occurred.

Expect another ½ inch of water tonight into Wednesday, bringing another 6 inches of snow. Increasing daytime temperatures may keep the avalanche hazard elevated through Thursday. Backcountry users should avoid steep loaded slopes, especially during the heat of the day.
