Good Morning.† This is Ethan Greene with the
Our not-winter continued last night with an inch or two of new snow with a tenth to a quarter inch of water.† As of yesterday afternoon the rain/snow line was near 7,000í.† Overnight temperatures dipped into the mid 20ís at 8,000í and upper teens at 10,000í.† The winds have been from the northwest in the 10 mph range in most areas.† Along the high ridgelines the winds have been in the 20 mph range with gusts over 40 mph.
The snow surface is a mix of firm crusts and damp powder under a few spongy inches of fresh snow.
While itís been a bit dreary
in the mountains the past few days, we did pickup a bit of snow and a fair
amount of water.† Storm totals appear to
be around one inch of water at most locations.†
If the snow felt like a wet noodle on Thursday itís more like a frozen wet noodle this morning.† Temperatures have been cooling over the past two days, and with overnight lows in the mid 20ís I suspect the snow is frozen at most locations.† Even though we havenít had much of a winter, we still have a few avalanche issues to keep in mind today.
First and foremost is the sun.† Although the new snow is not the greatest snow on earth, if it gets a good shot of sun wet sluffs or point releases are likely.† Remember that point-release avalanches are especially dangerous if they can push you off a cliff or into a gulley.† Second is the wind.† We still have some hard wind slabs that formed earlier in the week.† Although they are mostly stable, I have been tiptoeing around them for the past few days.† The most likely place to trigger a wind slab is a steep rocky area that generally has a shallow snowpack or in an area that avalanched earlier in the season.† Lastly there is an isolated chance of triggering an avalanche that will break down into the deeper snow.† These deep slab avalanches could be triggered by smaller surface-snow avalanches on northwest through east facing slopes, steeper than 35 degrees, in areas above 9,000í.
The upper portions of the
Bottom Line (SLC,
The avalanche danger is generally isolated or LOW this morning, but may increase to MODERATE as the sun heats the new snow during the day.† With low clouds heating could occur on all aspects.† There is also a MODERATE danger of triggering an avalanche into deeper weak layers on northwest, north, northeast and easterly facing slopes, steeper than about 35 degrees and above about 9,000 feet and on very steep rocky slopes with hard wind deposits.
The Pacific storm system that
bought us warm and wet weather for the past few days is moving off to the
east.† Today high pressure will build in
