Lo esencial

Heads up, a dramatic warming event is on tap for the next few days creating the potential for increasingly reactive avalanche conditions!

A MODERATE danger remains for human triggered avalanches failing on a buried persistent weak layer on slopes steeper than 30 degrees that face NW-N-NE-E. Avalanches failing on this layer will be 2'-3' deep, and warming temperatures over the next few days may increase the likelihood. Continue to temper your ambitions for steep, northerly facing terrain.

With a strong sun and warming temperatures we'll see a MODERATE danger for loose, wet avalanches on sun exposed slopes. Signs of instability include rollerballs, pinwheels, and sloppy wet snow. Get in and out early, and stay off of, and out from under steep slopes when they start to get wet and sloppy.

    A persistent weak layer of loose, sugary faceted snow exists on NW-N-NE-E aspects beneath a slab that is 2'-3' thick. The weakest snow exists on northerly aspects right around treeline and below. Above treeline, weak layer distribution is more variable but the problem has been compounded by recent wind drifted snow. Stability tests show that avalanches are becoming harder to trigger on this weak layer but that could change with dramatically warming temperatures over the next few days. Snow, like people doesn't like rapid change, and it has a tendency to react poorly. The bottom line is that we could see an increased likelihood for human triggered avalanches failing on this weak layer over the next few days.

    With a strong sun and dramatically warm temperatures over the next few days we'll need to be alert to signs of wet instability on all sun exposed slopes. Signs of instability include rollerballs, pinwheels, and sloppy wet snow. With good re-freezes overnight, you should be able to find supportable surfaces and corn snow on SE-SW aspects, but it's that time of year when you need to get in and get out early. Stay off of and out from under steep slopes when they start to get wet, sloppy, and unsupportable.

Recent Activity

There are no recent reports of avalanches from the Abajo range.

Snow and Weather

High pressure is building over the region and warm air will begin filtering in from the SW. Today we'll see sunny skies and temperatures rising up into the mid 40's at 10,000'. Temperatures will steadily increase each day with the potential for record breaking heat this weekend. A low pressure system is currently projected to make landfall on the California coast on Monday bringing a chance for snow to our area on Tuesday.

Snowpack

With the approaching heat wave, we'll be eyeing the snowpack closely to see how it reacts. In addition to the usual concerns for loose, wet instability on sun exposed slopes, this dramatic warming could make human triggered avalanches, 2'-3' deep more likely on northerly aspects where we still have a buried persistent weak layer of loose, faceted snow. Over the long run, the upcoming warm temperatures should help to strengthen the snowpack, but in the short term, this transition could make things more volatile. Continue to keep it dialed back this weekend. Harvest corn on south facing slopes and get in and out of the mountains early.
