Forecast for the Moab Area Mountains

Issued by Max Forgensi for
Sunday, February 24, 2013

The Bottom Line for Sunday will be an Avalanche Danger of Considerable for wind slabs and storm slabs at all aspects and elevations in the La Sal Mountains, which received the Lion's share of the storm in southeast Utah. Natural avalanche activity is possible while human triggered avalanches are likely.

Special Avalanche Bulletin

An additional 0.8" of H20 fell before midnight in the La Sal Mountains with plenty of strong winds that started off from the southwest and veered to the north this morning. 12" of snow fell at the Geyser Pass TH in the past 18 hours, increasing the avalanche danger to Considerable for storm snow and wind slabs.

Sunday and Monday will be days to reevaluate the snow stability and distribution. Use these days for observations into avalanche terrain but keep off the throttle and stay safe.

Weather and Snow

The La Sal Mountains have received over 50 cm of powder the past four days in Gold Basin. Great riding conditions exist. Be prepared for touch and go driving conditions into the mountains today. 4WD and chains are recommended.

Recent Avalanches

There were plenty of sluffs observed on steep slopes greater than 35 degrees yesterday on all aspects. I expect more today with the addition of some natural wind slab avalanche activity.

As the sun hits the slopes today, storm snow will start to sluff and may start slab avalanches. Today will be a good day for observing these types of avalanches.
