Widespread MODERATE avalanche danger will form quickly today on all aspects at all elevations on slopes 35 degrees and steeper in response to daytime warming. The vast majority of instability that occurs today is likely to be human triggered, but an isolated natural avalanche event is not out of the question.

This morning, MODERATE avalanche danger exists near and above treeline in recently wind loaded areas on NW-N-NE-E aspects on slopes 35 degrees and steeper. A transition will occur during the late morning and afternoon hours to warming and wet snow instability. Pockets of CONSIDERABLE avalanche danger are expected to form at all elevations on all aspects on slopes 35 degrees and steeper by this afternoon.

Early this morning, avalanche danger is LOW for all elevations and aspects. Widespread MODERATE avalanche danger will form today at all elevations and on all aspects in response to daytime warming. The vast majority of any avalanche activity that occurs today is expected to be human triggered. An isolated natural avalanche occurrence is unlikely, but not outside the realm of possibility during the late afternoon hours.

We have stopped issuing daily avalanche advisories until the fall of 2012. The avalanche danger can and will change quickly this spring. Continue to monitor changing conditions and use caution when traveling in the backcountry. For general spring avalanche information read the full spring avalanche statement.
