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 backcountry avalanche danger is still LOW in most areas. However, there are probably some drifted pockets where you could trigger shallow soft slab avalanches and with a MODERATE danger. You'll most likely find these on exposed upper elevation slopes steeper than about 35 degrees with freshly wind-deposited snow...


CURRENT CONDITIONS

Looks like we picked up more, or at least as much, snow down in Cache Valley as we did in the mountains where 8000' Snotel sites report 3 or 4 inches of new snow from yesterday. Snow cover is limited to north facing upper elevation slopes, and hitting rocks or other shallowly buried obstacles probably still presents the largest safety concern....

There's still just not enough snow for backcountry riding, and you pretty much have to stay on snow covered upper elevation roadways. Remember to slow down and watch out for pedestrians, especially in congested areas like Tony Grove.


RECENT ACTIVITY

Its been close to two weeks since our last storm and any local avalanche activity...


THREAT #1

WHERE PROBABILITY SIZE TREND
      Over the next 24 hours.

Overnight easterly winds may have built some small fresh wind slabs in rather unexpected places, and you might trigger soft slabs around a foot deep on some steep upper elevation slopes. I'd be especially cautious on exposed slopes and around terrain features where cross-loading has drifted-in significant light fresh snow.


MOUNTAIN WEATHER

It'll be very cold today in the mountains with cloudy skies and light snow.....Expect continued moderately strong east-southeast winds to keep wind chills quite low. Mountain temperatures will drop well below zero tonight, with -6 forecast.

Looks like we'll have to be satisfied with this nickle and dime action as the next Pacific storm will mostly impact southern Utah...We may see a bit of snow in the mountains tomorrow, but not the significant accumulations that are likely down south. A storm for later in the week looks more promising, but don't get your hopes too high...


GENERAL ANNOUNCEMENTS

We will be issuing intermittent avalanche advisories as conditions warrant. I'll begin to issue regular advisories later in December and when the winter season really gets rolling....
