This concludes our avalanche bulletin season. However, avalanches still persist. Mainly, we are faced with spring time conditions, cool mornings, hot afternoons. Danger will be HIGH on hot afternoons. Have a safe and enjoyable spring and summer.

Weather Forecast

The weekend of May 4 and 5 we expect to see double digit temperatures and HIGH avalanche danger in the afternoons (low in the cold mornings). Because there is still significant amounts of snow a high elevations expect the biggest spring avalanche cycle starting Saturday afternoon (May4).

Snowpack Summary

As springtime and warm temperature approach expect to see a daily swing between cool mornings and hot afternoons. This means the avalanche danger will be low in the morning and high in the afternoon. Expect the snowpack to become isothermal in the afternoon.
