current conditions The 1st day of Spring...though between me and you...and the snowpack, last Thursday/Friday's heat wave marked the transition between one season to the next. Don't abandon the winter gear yet - we have more storms on the way - as today's increasing clouds and southwesterly winds usher in the first of two systems. Skies are already partly to mostly cloudy, temps have increased through the night (mid to upper 20s) and winds are southwesterly blowing 15-20mph with gusts into the 30s. |

recent activity None...though there was a close call in the Moffit Peak area of the Uintas yesterday - check the Uinta advisory for more details.... More photos continue to filter in from last week's wet avalanche cycle. Brett started a collection here. |

description
Even with a LOW avalanche danger, there are a few places where a person could trigger a small slide. In extreme terrain or on very steep slopes, there could be serious consequences if you go for a fast icy ride, are pushed off a cliff or into trees. Watch out for:

weather The first storm arrives today, accompanied by a subtropical moisture tap. It doesn't look like this will translate to a lot of precipitation for the Wasatch, but at least we'll have a high rain/snow line (8-8500'). Temps will nudge near freezing at 10,000' and the mid 30s at 8000'. Winds will be on uptick from the southwest, blowing 30-35mph by the afternoon and perhaps into the 40s along the most exposed ridgelines. I suspect we'll see 2-4" of dense snow by early evening. A cold front arrives tomorrow, ushering in a new round of snow with snowfall crashing to the valleys. Mountain temps plummet to the mid-teens with mountain snowfall amounts in the 6-10" range expected by late Thurs/early Friday. Quite a bit of instability noted with tomorrow's storm...lightning, lake effect bands possible...and periods of convective snowfall will lead to widely variable snow amounts even from drainage to drainage. Mountain temps continue to plummet to the single digits by Friday. We stay unsettled through Saturday. |
