Pro Obs: Another shot of the slab avalanche mentioned in previous post. Taken 5/18/17 from Hwy 20, Blue Lake Trailhead, Washington Pass

Pro Obs: Photo from yesterday (5/18) showing Blue Lake Peak and the terrain west of the Liberty Bell group, Washington Pass. As it has for months now, the Blue Lake Peak cornice remains a formidable obstacle for those interested in the classic "Birthday Tour" - and is still a major threat to nearby terrain and Spire Gully proper. Zoom in and a large fracture line is evident right of center of this pic. Locals are unsure of when that slab released...probably 7-10 days ago. Guessing this failed on mid-Feb crust interface, 6800 ft, NW aspect. New snow from early this week needs more time to settle and undergo a few MF cycles...expect an active shed cycle above 6k with small Loose Wet avalanches persisting. Low-mid elevation glide problems should persist a while longer as well...watch out around rock slabs and unsupported features. Snowpack is still deep up high, with 3+ meters at 6500 ft in Portly Bowl! 5/19/17 - Jeremy Allyn @julbousa @backcountryaccess @outdoorresearch @k2skis @lineskis

Yesterday the storm brewed thunderheads, strong winds, and lots of graupel laced snow for Mt. Hood. Timberline came up with about 30" storm total, over 3" water- pretty hefty for May! The snow accumulated at cooler temperatures but now warming, and sun soon to follow. Storm and wind slabs are out there, most notably near and above treeline. These pics at creek level, and ~4800', show the melt back around rocks but winter snow conditions. This cycle is primed to produce avalanches; just a matter of when and where.

The NWAC Data Network by Mark Moore, May 2017
.
Weather data is real, it's not a fake.
It creates the snowpack like layers of a cake.
.
Whether the cake is solid—and stable when stressed…Or fails and slides when put to a test.
.
It's all how those sensors tell what they know, And whether the snowpack is a friend or a foe.
.
When lacking a forecast during the off-seasons,The data is there for many good reasons.
.
You can reconstruct how layers came together, And how weak layers settle as a result of the weather.
.
So the data network and sensors it comprises,Are part of the info that helps limit surprises.
.
So help it out as best you are able.To help keep you on top when snow is unstable.

It's starting to feel like spring in the PNW which means many of us are planning big adventures. NWAC will not be producing any more forecasts for the season but you can still find outlooks and telemetry on our website.
