Danger Rose Tutorial

The avalanche danger is mostly LOW with pockets of MODERATE danger for fresh, shallow, wind slabs in steep, wind exposed terrain. As always, avoid steep slopes with fresh wind drifts. If the sun comes out, there may also be a MODERATEdanger of shallow, damp sluffs on steep sun exposed slopes.


A quick cold front came through last night dropping a measly 2 inches in the Cottonwood Canyons and 5 inches in the Ogden and Logan area mountains. The Salt Lake and Provo area mountains will make a valiant attempt to catch up in the next couple hours, but the storm is rapidly dying. The hot tip for the day is to head to the northerly parts of the state where they have been getting a few inches of snow the past couple days in addition to this latest snow. South of I-80, you should hope for the best but prepare for the worst. With the cold temperatures, the pre-existing, wet snow at lower elevations will resemble concrete traffic barriers with just enough of a dusting on top to make them hard to see. Yesterday, I found the pre-existing dry snow to be crusted and tracked-up and in bad need of some freshies. It’s feeling pretty lonely in my cubicle this morning here at the National Weather Service. The only backcountry observation I got from yesterday was a UDOT forecaster in the Salt Lake area mountains who was paid to be out there and he didn’t seem too excited. Temperatures have plummeted to 5 degrees on the highest peaks and 10 degrees on most ridges. Winds blew overnight 20, gusting to 35 from the west and 30, gusting to 50 at 11,000’. Winds have dropped significantly to 10 mph gusting to 15 from the northwest.


There was no new avalanche activity reported from the backcountry yesterday.


      Over the next 24 hours.

With the wet, pre-existing snow frozen solid and the dry, old snow mostly stable, your only avalanche hazard today will be fresh, soft, and mostly shallow, wind slabs. As usual, you should be suspicious of steep slopes with fresh wind deposits, which will look smooth, rounded and chalky. Most of them will be about 6 inches deep, but could be up to a foot on some slopes.


      Over the next 8 hours.

If the sun comes out this afternoon, we may see some shallow, damp sluffs on steep, sun exposed slopes. I suspect it will be cold and windy enough to keep this to a minimum, but you should watch for them.


The snow has ended north of I-80 and light snow showers should continue south of I-80 this morning and call it quits by mid morning. Temperatures will remain quite cold today with ridge top temperatures clawing their way up to mid to lower teens with a 10 mph wind from the northwest. Clouds should slowly clear out by mid day. Overnight, temperatures will remain very chilly, around 8 degrees on the ridge tops. You should enjoy what little powder we have because ridge top temperatures will pop right back up to freezing for the weekend.

The extended forecast calls for continuing clear, warm weather with a stronger storm for Thursday.
