All aspects, above & below treeline, have had recent Loose-Wet Avalanche activity. Southerly aspects definitely have had the majority of this type of avalanches but nights without freezing have loosened the uppermost portion of the snowpack across the BWRA. Radiation Recrystallization has occurred on many slopes & could prove to be a catalyst for future avalanches if we receive more precipitation.
Cornice Falls have proven to be a considerable contributor to the avalanche problem lately. The moderate to strong winds we've had in the BWRA has created a landscape dominated by wind-scouring & snow deposition. Melting & movement of cornices has allowed Loose-Wet, Loose-Dry, & Wind-Slab avalanches to release themselves in quantity & localized in Terrain Traps.
Our deep snowpack is melting quickly from the top down. Surface faceting & Radiation-Recrystallization is occurring and may prove to be a future avalanche hazard. New snow we received Monday & Tuesday had formed wind-slabs & grew cornices in mass. Since Wednesday the new snow has been actively shedding itself in a variety of ways including: Loose-Wet, Loose-Dry, Wind-Slab, & Cornice-Fall.
Weak low pressure will bring breezy conditions today with light showers possible towards the Oregon border. Monday through Wednesday, additional systems will keep breezy conditions going with light shower chances spreading farther south. Drier weather will return late in the week. Temperatures near average today will fall to slightly below average this week.
