Avalanche Advisory
Advisory: Abajo Area Mountains Issued by Eric Trenbeath for Friday - April 8, 2016 - 6:54am
bottom line

The avalanche danger is generally LOW this morning but will rise to MODERATE as the day heats up. Be alert to signs of wet instability such as roller balls, pinwheels, and sloppy wet snow, and stay off of, and out from under steep slopes when these signs are present. Give cornices a wide berth when walking on ridge crests and avoid being under them, especially as daytime heating progresses.

description

Overall, things have been pretty quiet as far as wet slide activity goes, and with clouds moving in today, you would expect that trend to continue. My concern today is the lack of an overnight re-freeze. It won't take much sun today to loosen the surface snow on sun exposed slopes.

Additionally, there exists the potential to trigger a wet slab in areas where the snow pack is shallow and saturated clear through. Yesterday, I found areas where stopping on a sled would result in it dropping down into unsupportable, loose wet snow underneath, and if I got off the machine, I would punch right through up to my waist. Not a good sign.

Be alert to a rapidly warming snowpack today. Watch for the usual signs of instability such as pinwheels, rollerballs, and sloppy wet, or punchy snow, and stay off of and out from under steep slopes when these signs are present.
