Danger Rose Tutorial
|
There is MODERATE (2) danger at upper and mid elevations in the backcountry. You could trigger wind slab avalanches 1 to 2 feet deep in exposed terrain, especially near ridge-tops and in and around terrain features like cliff bands, sub ridges, and gullies. Solar heating could rapidly cause a heightened danger of loose wet avalanches entraining significant moist fresh snow on steep slopes exposed to prolonged direct sun. I’ve included pockets of CONSIDERABLE (3) danger in today’s rose since triggered avalanches are probable in some areas, although they should be fairly predictable and mostly manageable.
Evaluate the snow and terrain carefully and continue to follow safe travel protocols... |

CURRENT CONDITIONS |
|
Yesterday was again winter-like up high, with graupel, high winds and periods with truly heavy snowfall. Expect fairly nice powder conditions on sheltered upper elevation slopes today. It's 20 degrees at the Tony Grove Snotel at 6:00am this morning, and the station reports a storm total of 8 tenths of an inch of water equivalent in about 10 inches of new snow. There's currently 70 inches of total snow at the site, containing 63% of average water for the date. The 9700' Campbell Scientific-Logan Peak weather station reports a temperature of 13 degrees this morning, and a north wind, currently averaging around 12 mph. |

Wind slabs consisting of yesterday's drifted snow are possible in steep exposed terrain. We noted drifts and some cracking yesterday around a foot deep and deeper in places. Even shallow or soft wind slabs could be a problem if you get caught and carried into trees or other terrain traps below.... I'd expect some stiffer and somewhat more substantial slabs today up high |

Expect a heightened avalanche danger today as the cold fresh snow is rapidly affected by solar heating... Loose wet avalanches will be likely as soon as the surface of the new snow becomes saturated.... Avalanches involving the several inches of new snow could entrain substantial quantities of snow in decent and pile up deeply, especially on longer sustained pitched slopes... |

MOUNTAIN WEATHER |
|
The weekend looks clear and sunny with warmer temps moving in. Expect mountain high temperatures above freezing today, and much warmer in sheltered sunny areas...Similar fair weather is forecast for Sunday.... The next wave of storminess and a chance for more snow comes on around Tuesday... |
