** IMPORTANT ANNOUNCEMENT **

As of March 30th, COAC has suspended backcountry avalanche advisories and pro observations until further notice.

On March 23rd, Governor Brown of Oregon issued Stay at Home orders for the public regarding the COVID-19 outbreak. The directives are clear in that “to the maximum extent possible, individuals stay at home or in their place of residence.” On March 27th the Deschutes National Forest issued a closure of all developed recreation sites including trailheads and snoparks. COAC is committed to supporting our community, local emergency services, and agency partners and because of this we felt it important to cease operations as we all work together to minimize the impacts and spread of COVID-19.   

This decision was not taken lightly. Aside from the need to maintain congruency with the Governors' orders, there are inherent risks with backcountry activities in alpine environments and it’s important to consider unnecessary exposure to COAC forecasters, first responders, and local medical staff in light of the current situation.

We look forward to getting back into the mountains and providing you all with the tools to recreate safely in the backcountry. Until then we thank you for your continued support and wish all our mountain community the best of health and wellness.

Snowpack Summary for 3/13/2018

THIS Avalanche Advisory EXPIRED ON Mar 15, 2018 at 10:20 pm
Avalanche Advisory published on Mar 13, 2018 at 10:20 pm
Issued by Aaron Hartz
Bottom Line
The spike in air temperature today brought a touch of rain to the mountains. Soon after, the incoming storm cooled down and rain turned to snow. Any signs of loose wet avalanches from the rain, will have disappeared with the decreasing air temperature. This storm will probably not make your powder dreams come true, but it will give a good reset to the snow surface. Even with a few inches of new snow we may see the formation of new wind slabs on lee slopes. Small cornices have been spotted here and there on ridge tops. While cornices are not large or widespread, watch out for them when traveling near ridge tops.
Avalanche Character 1: Wind Slab
With the wind forecast to be out of the west through south over the next few days, watch for new wind slabs forming on easterly and northerly facing terrain near treeline and above treeline. The wind is forecast to be light over the next few days, but it could be just enough to move snow. Wind slabs will probably be fairly shallow, but are still something to watch for.
Snowpack Discussion
Old wind slabs from the last storm are now well bonded. No significant weak layers have been found recently in the snow pack. Any instabilities in the upper pack will most likely be associated with the incoming storm snow/wind slabs.
Recent Observations
No reports of recent avalanche activity.
Mountain Weather
Although this storm will not drop a whopping dump of snow we could get up to 5 or 6" tonight through Wednesday. Winds are forecast to be out of the West through S over the next few days. Nighttime lows will be in the teens and day time highs in the 20'sF over the next few days.
