special announcement Great news… so far there haven’t been any avalanche fatalities in Utah this winter! It has been 26 years since we’ve had a fatality-free winter. Let’s keep it that way and stay safe this spring. Our goal is for everyone to enjoy the Greatest Snow on Earth and come home safe every day. The final regular advisory will be this Sunday, April 16. For the rest of the month we'll issue Friday updates for the central Wasatch Mountains and updates any time there is measurable snowfall; however, we will discontinue issuing avalanche danger ratings after Sunday. Although we will be shutting down regular operations, we will continue to post observations through the end of the month as we receive them, so please do continue to send them to us. You can check the latest observations here. We also follow avalanche-related activity on Instagram - be sure to tag your photos with #utavy . |
current conditions It's a cold morning for this time of year with temperatures in the low to mid 20's F. Skies are clear, and light westerly winds are blowing 5-10 mph with some gusts in the teens. Week in Review [Detailed Version] A storm system entered the region this past weekend, with warm temperatures and a high rain/snow line on Saturday April 8th. A cold front with an ample moisture supply late Saturday night and well into the day on Sunday provided nearly 18-24" in the Cottonwoods and Ogden mountains, with 8-15" along the Park City ridgeline. The Provo mountains recorded 3-6". Limited avalanche activity was reported with this storm, with a few slides breaking at a graupel interface of the old snow surface, or within a density inversion within the storm snow. Monday brought clearing skies, but cool temperatures kept wet activity to a minimum. A short-duration wind event on Tuesday morning created pockets of wind drifts in isolated terrain, and a wind slab avalanche was triggered by a party of skiers hiking uphill at Snowbird Ski Resort. Another small wind drift was triggered in White Pine in Little Cottonwood canyon. Warming temperatures highlighted Wednesday and Thursday, but wet activity was minimal. A dry cold front entered the region Thursday evening, providing a solid refreeze of the snowpack by Friday morning. |

description
Cold air temperatures and clear skies gave the snowpack a solid refreeze last night. Because the snowpack has gone through melt-freeze cycles all week and today will remain cool, there should be minimal wet snow avalanche activity. Falling on hard, icy snow may be more of a danger than avalanches today. The only other thing to look for are old wind slabs formed Tuesday during a period of strong S winds. Watch the video below about things to watch for this spring. |
weather Today will be a beautiful sunny day with relatively cool temperatures. Temperatures at 9000 feet will struggle to break into the 40's F. Winds will remain light blowing 5-10 mph from the W and NW. |
