Danger Rose Tutorial
|
The avalanche danger is generally LOW with pockets of MODERATE danger from localized wind slabs along the highest peaks and ridgelines. As always, avoid steep slopes with recent wind deposits. Also, watch for rocks hiding beneath the light powder snow on the surface. |

CURRENT CONDITIONS |
|
We've had a few variable, mountain-level clouds overnight and ridgetop winds have picked up to 15 mph from the west and northwest with winds up to 30 on the highest peaks. Temperatures are around 12 degrees.
Sundance mid mountain shows 6 inches of snow and the Timpanogos Divide automated station at the summit of the Alpine Loop Road shows 9 inches. So you will have to get up to very high elevations to find enough snow for recreation.
The upper elevations of the Salt Lake area mountains have 3 feet of settled snow depth. |

RECENT ACTIVITY |
|
Yesterday, there were no reports of human triggered avalanches despite many people crawling all over the upper Cottonwood Canyons near Salt Lake City. There were no observations from the Provo area mountains. |

Winds have picked up overnight on the highest peaks to 30 mph gusting to 40 from the northwest but on most ridgelines, the winds are a more reasonable 10-15 mph. With about 6 inches of very low density powder on top, it doesn't take much wind to create dangerous wind slabs. You will find these mostly at the highest elevations and high ridgelines in downwind terrain. Luckily, you can easily spot wind slabs with their smooth, rounded shape, their hollow sound and their slabby feel. Today, as always, you should avoid any steep slope with recent wind deposits. Otherwise, the snowpack is mostly very stable. |

MOUNTAIN WEATHER |
|
We should have scattered, mountain-level clouds increasing to mostly cloudy by afternoon. Ridgetop winds will blow 15 mph from the northwest with speeds up to 30 mph on the highest peaks. Ridgetop temperatures will rise today from 12 degrees this morning to near 20 this afternoon, with temperatures rising to the mid 20's down at 8,000'.
The extended forecast calls for a brush-by storm passing to the east of us tonight and again on Sunday bringing a chance for light snow showers without much accumulation. |
