In sintesi

The avalanche danger is MODERATE for wind drifted snow at all upper elevations and at mid elevation northeast through easterly facing terrain. Strong southerly winds will create dangerous slabs of snow across specific terrain features and human triggered avalanches are possible. Rain is possible today at the low to mid elevations and there is a MODERATE danger for wet snow avalanches. I will be updating the Salt Lake City, Ogden and Provo forecast Monday morning (April 15th) by 7:00 am.

    Strong southerly winds picked up last night around 9:00 pm and continue to blow with speeds of 15-25 mph gusting into the 30's and 40's at upper elevations. This will certainly create a fresh batch of new wind drifts and slabs across the mid and upper elevations. Winds typically load snow on leeward slopes, gullies, bowls, and mid slope break-overs. Shooting cracks along with thick upside down snow are red flags and shouldn't be ignored. Look for and avoid any steep slope that looks like it's been effected from the wind. Human triggered avalanches are possible.

    With no overnight re-freeze of the snow the mid and lower elevations will remain damp, wet and soggy. Wet loose avalanches will be possible in any steep terrain. To complicate the issue we are expecting the rain/snow line to be around 8,000'-9,000' feet in elevation today and into this evening. Anytime we have rain falling on dry snow it instantly spikes the avalanche danger and wet loose sluffs will be instantaneous. Seek out lower angled terrain and avoid run-out zones if for some reason we see heavy rain on snow today.

Special Announcement

Daily early morning avalanche forecasts will end today, Sunday, April 14. However, with storms this week we will issue early morning forecast on Monday (April 15th) and on Friday, Saturday, and Sunday of Easter weekend (April 19-21). Throughout the rest of April, we will issue intermittent updates with any snowfall or other significant weather events, and we will continue posting observations.

Drew Hardesty just penned another wonderful blog piece, Meditations on Skiing the No-Fall Zone.

Recent Activity

One observer reported triggering a small wind slab yesterday and some fast running sluffs in the steep terrain. No other backcountry observations came in from the Ogden area.

Snow and Weather

The southwest winds ramped up ahead of a series of storms that will impact the mountains for the next few days. 9,500' anemometers are currently spinning 25-35 mph gusting into the 40's. Temperatures remained warm in the Ogden area mountains with many weather stations up to 8,500' staying above freezing.

Today: As the storm moves in from the Pacific the southerly winds are forecasted to increase today and into tonight with speeds of 30-40 mph gusting into the 50's at upper elevations . Clouds are moving in from Nevada as I type this and will arrive shortly after sunrise with a chance for a couple of inches of snow by the end of today. The temperatures will be warm and the rain snow line will be 8,000'-9,000' feet in elevation.

Monday: Strong southerly winds will continue in the morning hours before a small storm rolls through midday allowing for a better shot of snow. Monday evening the winds return ahead of a much better storm on Tuesday.

Tuesday: Snow flurries. By the end of the day on Wednesday we could see 9"-18" of new snow.
