Logan Avalanche Advisory

Forecaster: Toby Weed

BOTTOM LINE

Danger by aspect and elevation on slopes approaching 35° or steeper.
(click HERE for tomorrow's danger rating)


Danger Rose Tutorial

The danger level remains LOW (or Level 1) in the backcountry around Logan. Avalanches are generally unlikely. Shallow snow conditions exist dictating a conservative and slow approach.


CURRENT CONDITIONS

Yesterday, we found very nice shallow powder and dust-on-crust conditions on smooth slopes at upper elevations. Unfortunately, warm temperatures last week melted off most sunny slopes and forested areas, and there are many places with bare ground and a skiff of new snow....

Remember to keep the speed down and watch carefully for shallowly buried rocks and other obstacles. Also, the Tony Grove Road is not maintained for wheeled vehicles in the winter. Expect patches of ice, deepening snow, and deteriorating driving conditions.


RECENT ACTIVITY

No recent avalanche activity has been observed in the Logan Area, and the shallow underlying snowpack at upper elevations is fairly dense and supportable... The few inches of powder from Monday and through the week are subject to a large temperature gradient with the cold air temperatures contrasting significantly with the warm October snow below. I noticed a tell-tail granular or sugary texture in the cold surface snow. This is faceting, indicating the potential development of a persistent weak layer which may well haunt us later on in the season


THREAT #1

WHERE PROBABILITY SIZE TREND
      Over the next 24 hours.

Its a good idea to practice with your rescue equipment in the early season.... Shallow, simple problems in snow, or even in urban leaf piles, are recommended.


MOUNTAIN WEATHER

The pattern will continue with fairly benign and cold conditions. Expect continued cloudy weather, but only a little snowfall as storms clip by from the north. A change in the weather pattern is likely around the middle of next week, with a milder and moist zonal flow in the works....
