Avalanche Advisory

Above 8,500 ft.
7,000-8,500 ft.
Below 7,000 ft.

bottom line Pockets of MODERATE danger exist due to the continued and extensive wind drifting. Cracking and collapsing are excellent indicators of local instability. Human triggered slides are possible in localized terrain.

current conditions Skies are partly to mostly cloudy this morning. Headlines, however, remain the winds. The southerly winds picked up last night and are blowing 35-40mph with some gusts into the 60s and 70s. It's not pretty. Temps hover in the upper teens to low 20s. Low to mid elevation south and west aspects suffered some sun-damage yesterday...but at least you can find bullet-proof hard wind damage in the open exposed alpine terrain. Best bets would be to hunt for mid elevation sheltered terrain below tree-line. Which - as it happens - is where the dragon lives these days - more below- |

description
Pockets of hard and soft wind drifts will be found in a wide variety of areas...and may be increasing stubborn with the continued loading today. Remember - soft slab - you're in the slab....hard slab - you're on top of the slab. Hard slabs are notorious for allowing you to get well out onto the whale's back before it shatters. |

weather We'll have partly to mostly cloudy skies today with moderate to strong southerly winds along the ridgelines. Expect sustained speeds of 30mph with gusts to 50. Temps will be in the low 20s. A splitting system off to the west will keep us in a south to southwesterly flow through the next couple of days until it ejects inland and brings abundant moisture...to southern and central Utah. More unsettled weather and snow is likely over the weekend and into next week. More with our Mountain Weather update later. |
