Bottom Line for the Ogden area mountains:

Dangerous avalanche conditions exist in the mid and upper elevations of the Ogden mountains - as the snow piles up and the winds continue to blow, the avalanche danger will rapidly rise to CONSIDERABLE on steep, wind drifted slopes. Slides running on the old, hard ice crusts, will be larger, faster and further running than usual.  If you head into the backcountry today, use conservative decision making, careful route finding and good travel habits. Training and experience are essential for backcountry travel today. Below about 8,000', where the new snow is falling on bare ground, the avalanche danger is generally LOW.

The cold front is racing across the Great Salt Lake, and is forecast to reach the northern Wasatch mountains between 8 and 10 am. Ahead of the front, strong southwesterly winds have been tearing across the range, with 30 to 50 mph averages, and gusts in the 40 to 60 mph range. Even in more sheltered locations and at lower elevations, gusts are in the 20's and 30's. Pre-frontal precipitation on the southwesterly flow in the Ogden area mountains is in the 3 to 6” range. Temperatures are currently in the low 20's to near 30.

No new avalanche activity was reported from the backcountry or the resorts yesterday, however, the avalanche danger is increasing today. I expect new snow and wind slab avalanche activity, with slides running further and faster than normal on the hard crusts.

Full conditions today... the National Weather Service has issued a Winter Storm Warning that will remain in effect until 5 pm Sunday, with heavy snow and strong northerly winds creating wild winter conditions. Snow totals of a foot or more expected by 5 pm, with lightning and intense precipitation rates of 2 to 4 inches per hour possible around frontal passage. The winds will shift to the northwest this morning, and remain in the 20 to 30 mph range, with gusts to 50 at the 10,000' level. Gusts to 70 mph are possible across the highest peaks. Temperatures will fall throughout the day, into the low teens to single digits by evening. Periods of snow tonight, with storm totals of 16 to 24” by Sunday afternoon, with temperatures near zero. A cold and unsettled pattern, with more snow, will continue through much of next week.
