THE AVALANCHE WARNING CONTINUES FOR ALL THE MOUNTAINS OF NORTHERN AND CENTRAL UTAH...SOUTHEAST IDAHO...THE WESTERN UINTAS...AND SOUTH TO THE MANTI-SKYLINE PLATEAU TO I-70. HEAVY SNOW AND WIND HAS PUSHED THE AVALANCHE DANGER TO HIGH, BORDERING ON EXTREME. AVOID BACKCOUNTRY TRAVEL ALTOGETHER...AS LARGE NATURAL AND HUMAN TRIGGERED AVALANCHES REMAIN LIKELY IN MANY AREAS ACROSS THE STATE. THIS WARNING DOES NOT INCLUDE SKI AREAS OR HIGHWAYS WHERE AVALANCHE CONTROL IS NORMALLY DONE.

UDOT closed Little Cottonwood Canyon last night for avalanche control work slated for this morning. Estimated opening is 9:00 am Sunday. Backcountry restricted, please stay clear of all avalanche paths on north side of canyon.

SR 158 to Powder Mountain closed for avalanche control work through the morning.

SR 92 into American Fork Canyon closed for avalanche control work.

By now many of you likely heard of the avalanche accident near Tibble Fork Reservoir in American Fork Canyon above Provo. A 21 year old woman snowshoeing with friends was caught and buried and reportedly submerged in the creek for 25 minutes prior to being excavated by her friends. As of our last information, she remains in critical condition.

Many areas of the Wasatch Range fell apart yesterday, with large, long running natural avalanches reported from Logan to Provo and many areas in between. Strong westerly winds and warming temperatures accompanying storm totals of 2-3' of heavy dense snow easily delivered the knock-out punch. It's not over - a natural cycle is occurring in the Ogden mountains now...

It's still snowing....with reported rain/snowlines to 7500' in some areas. Winds are westerly - and down from yesterday's searing velocities - but still gusty with hourly averages in the 20mph range with gusts to 45. Most areas picked up another 6-9" overnight...but here are the storm totals (snow/snow-water-equivalent) since Thursday night -

Logan area mountains ~ 30"/6"

Ogden area mountains - 25-35"/3.6-4"

Park City mountains - 18-23"/1.5-2.0"

Big Cottonwood Canyon - 36"/3.21"

Little Cottonwood Canyon - 23"/2.27"

Provo area mountains - 25-35"/3-5.0"

Almost too many to mention - though many many natural avalanches from elevations of 6000' to 11,000' on a variety of aspects. (More info can be found on our detailed info page, found in the menu at the top)

Logan, Ogden, and Provo went through a significant avalanche cycle yesterday...with naturals still being reported as I write...

• Accident at Tibble Fork reservoir (see above). We'll initiate our investigation today.
• Tri-County Peak (2nd hand report) - snowmobilers accessing Guardsman Pass from Big Cottonwood Canyon, riding the snow-packed road just beyond the Guardsman Pass into Bonanza Flats, remotely trigger Tri-County Peak 2-4' deep and 250' wide, pushing one or two of them off the road. No injuries were reported. This on a steep southeast facing slope at 10,000'.
• Canyons backcountry - An intentional cornice drop remotely triggers a 2-5' deep and 350' wide on a steep east facing slope at 9500'.
• Summit Park area high in Parley's canyon - a skier caught and carried, grabbed a tree, on a steep northeast facing slope at 8100'. Dimensions reported 14" deep and 80' wide.

Many naturals yesterday looked like this - (photo of Lost Creek avalanche above Provo Canyon - Kendall Wimmer)

We'll continue to see rain and snowfall throughout the day with an additional 4-8" possible. Winds will be westerly at 20-30mph. Temps will be in the mid to upper 20s at 10,000' and the low to mid 30s at 8000'. Snowfall will become more showery this afternoon through tomorrow with a break late Monday into Tuesday. Things ramp up again with a similar style storm on Wednesday through Friday.
