** 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.

Avalanche Advisory for Dec. 14 & 15

THIS Avalanche Advisory EXPIRED ON Dec 15, 2019 at 10:32 pm
Avalanche Advisory published on Dec 13, 2019 at 10:32 pm
Issued by Aaron Hartz
Bottom Line
The most recent storm has covered some of the logs, snags, and rocks. Things are looking up here in central Oregon, but still be cautious of those early season terrain hazards. On Friday, the powder skiing/riding was good. For those people venturing into the high country over the next few days, be cautious of lee slopes and wind slab avalanche potential.
Avalanche Character 1: Wind Slab
The windslab avalanche problem may be found in isolated areas in high alpine and near treeline terrain on north, east, and SE facing slopes. The windslab problem will not be everywhere. Look for signs of wind deposited snow as a clue for where this problem lies. If you see recent wind deposited snow, be cautious in avalanche terrain (slopes steeper than 30 degrees). If you find wind deposited snow, it will be possible to trigger a wind slab avalanche, although the likelihood of triggering a wind slab will decrease over the next few days.
Snowpack Discussion
The height of snowpack was greatly increased with the last storm. Above 6000 ft, we now have 60 cm (2 ft) + snow on the ground. According to recent reports the snow pack is mostly right side up, which means the less dense snow is in the upper portion of the pack.
Recent Observations
There have been no reports of avalanche activity or recent reports of unstable snow. There have been very few reports in general.
Mountain Weather
As of Friday afternoon/evening the storm is tapering off and snowfall is on back order. The forecast for the next few days are for more fair weather, if you are into that sort of thing. Wind will be light and predominately out of the west and shifting to NW and SW. Look for cold daytime highs in the low to mid 20's Fahrenheit over the next few days.
