Forecast for the Salt Lake Area Mountains

The avalanche danger is LOW. Watch for unstable snow on isolated terrain features. Remember that risk is inherent in mountain travel.
Minor sluffing is likely on the steepest slopes and isolated pockets of hard wind drifts may be found in odd locations. Dangerous slide-for-life conditions will exist on many steep frozen slopes.

Special Announcements
The Avalanche Research Program at Simon Fraser University is conducting an online survey to examine how people use avalanche safety information. They want to hear from all backcountry users to understand how they process information provided in public avalanche forecasts. Anyone who completes the survey before May 15th will be entered to win cash prizes.

Weather and Snow
Under a cold northwest flow, the mountain temperatures have plummeted into the single digits °F above about 10,000' while lower elevation trailheads are in the 20's °F. Winds are blowing from the northwest 10-15 mph gusting into the 30's across the upper elevations. At 11,000' the northwest wind is blowing 35-40 mph gusting to 60 mph. Winds at lower elevations such as Reynolds Peak (9,400') in Big Cottonwood are only blowing 5-10 mph.
Mountain temperatures will remain cold today with below-freezing temperatures above about 8,000'. Winds are forecasted to remain steady and may increase as weak wave ripples overhead ushering in some clouds and snow showers at times. We could see a trace to 2" of new snow throughout the day.
Riding conditions are grim as there is not enough new snow to keep you off the icy hard surfaces, and with cold temperatures and clouds in the forecast, I doubt many slopes will soften today. Yard work?

Description
Wind slabs: Even though the wind is cranking up high, it has very little snow available to transport, and much of it is probably blown well off the ridgelines or sublimated away. However, keep an eye out for small pockets of hard wind slab that might knock you off your game. They'll be quite smooth and chalky and possibly break above you.
Slide-for-life: Steep sustained slopes that are now frozen solid offer a one-way ticket to the bottom if you were to slip or fall in steep terrain. Axe, (ski)-crampons, whippet ski pole, will be useful today.
Glide avalanches: Glides, in general, are poorly understood but have been known to still release a day or two into a cold snap after a heatwave. It's always recommended to avoid the usual glide habitat like Stairs Gultch and Broads Fork and or areas with yawning glide cracks.
Cornices: Always a threat, particularly in springtime. Continue to give them a wide berth and avoid being underneath large overhanging cornices.
Additional Information
Information on outdoor recreation - The State of Utah created this webpage with information about recreating on both state and federal public lands during the current health crisis.

Skiing and riding at closed ski resorts - Some resorts allow access now, and some do not. Please check HERE for the latest info on ski area access.
