** 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 4/24/2018

THIS Avalanche Advisory EXPIRED ON Apr 26, 2018 at 7:30 pm
Avalanche Advisory published on Apr 24, 2018 at 7:30 pm
Issued by Aaron Hartz
Bottom Line
The daytime air temperature is bumping up on Wednesday and Thursday. This will likely lead to loose wet avalanches that could be small to large in steep terrain. This will be our chief concern over the next few days. If you are dropping into anything steep and committing, consider your timing. Enter big terrain during the cooler parts of the day,either early or after the sun has moved to a different aspect. Loose avalanche wet debris is thick and heavy and can easily sweep you off your feet in consequential terrain. Work the aspects and stay off of steep slopes in the direct sun during the heat of the day.
Avalanche Character 1: Loose Wet
Watch for loose wet slides on all aspects below treeline and solar affected aspects near and above treeline. Anytime you are seeing natural loose wet activity or roller balls, think twice about dropping into steep and committing lines.
Snowpack Discussion
The sun and warm temperatures will weaken the uppermost snow pack. While we do not have any weak layers of concern, the upper pack will lose cohesion and lead to the loose wet problem.
Recent Observations
Numerous small loose wet avalanches have been spotted around the region on a variety of aspects and elevations over the last few days. On Monday, a previous size D2 (large enough to bury, injure, or kill) loose wet avalanche was spotted in the Broken Top bowl (above treeline, ESE aspect).
Mountain Weather
We will have high pressure for another day or two with daytime highs in the mid to upper 50 degrees Fahrenheit. Wind is forecast to be out of the south through east over the next few days. Clouds may increase on Thursday and there is a chance of precipitation on Friday through the weekend.
