current conditions The southwesterly winds picked significantly a few hours before midnight – and at 10,000’ are averaging 15 to 20 mph, gusting in the 30s. Winds are racing across the highest elevation ridgelines, averaging in the 40s, gusting in the 50s and 60s. Temperatures have warmed into the upper 30s at mid elevations. Total snow on the shady, mid and upper elevation slopes is around 1 to 2 feet, and unsupportable in shallower snowpack areas. Sunny slopes are a mix of crusty snow and bare ground.

description
The wind is changing the landscape and avalanche danger today. Even before the storm and new snow arrives, the winds will be drifting old snow, and these small drifts will be crossloaded onto a variety of aspects and elevations. Key points:

description
After 3 weeks of high pressure, very weak faceted snow exists across the northern Utah mountains, wherever there was snow on the ground before this storm. The snowpack on the shady slopes consists of weak crusts and sugary faceted snow. Once we get some weight on these weak layers, dangerous avalanches could be triggered. We are watching this storm carefully to see if we over load these layers this evening or tonight. Right now, the storm is looking too small. |
weather Another case of incredible shrinking snow numbers – the hope now is for 4 to 9” of low-density snow by tomorrow morning. For today, moderate to strong, southwesterly winds until the afternoon frontal passage, with high temperatures at 9,500’ in the mid to upper 30s. Frontal passage is forecast for 3 to 5 pm, accompanied by a burst of heavy snow. Wind will shift to the northwest, and decrease after a few hours, and temperatures drop, into the single digits by morning. A few lingering snow showers are possible Thursday morning, with highs only in the teens and 20s, under a brisk, northeasterly flow. |
