Snoqualmie Pass

Several days of mild weather and minimal new snow have led to generally safe avalanche conditions at the Pass. Sadly, it also means travel remains treacherous, especially at lower elevations.

It feels like forever since it last snowed. Indeed, the last significant precipitation event was 12/10. Since then, mild temperatures, plenty of sunshine, and only a few inches of snow allowed the snowpack to heal. You might find some weak sugary snow (facets) or feathery grains (surface hoar) at or near the surface, but the snow should be generally strong below. 

Without any significant weather on Thursday, it’s hard to imagine an avalanche outside of extreme terrain. That doesn’t mean “shut your brain off.” Safe travel techniques help minimize exposure in case something unexpected happens. 

It’s not all doom and gloom. Smooth travel has been reported on well-packed trails, in higher elevation shaded areas, and where frozen surfaces soften in the sun. Other than that expect at best arduous and at worst hazardous travel. Variable snow surfaces, including breakable crust, icy slopes, wet punchy snow, and irregular slopes, can make simple terrain more challenging. Then there are all the things to hit: rocks, logs, flowing creeks, open holes, and shrubs. Give yourself some extra time and go slow to deal with this nasty combination of conditions and obstacles.
