It's spring out there! Avoid steep solar aspects especially in the alpine. Sudden intense warming from the sun will increase avalanche hazard.
Weather Forecast
Today will be calm before the storm. Expect cooler temperatures with afternoon freezing level to 1400m. Light ridge crest winds are forecast today, with an alpine high of -4 and and potential for isolated convective flurries. Starting this evening a low pressure system & front moving inland will bring up to 40cm of snow by Friday
Snowpack Summary
Windslabs exist in the alpine from S winds last week but are gaining strength. The surface snow became moist yesterday to 1700m(higher on S asps) but was still supportive to a riders weight. The Feb 27 layer is now down 60cm which is crusts on solar aspects and surface hoar on shaded aspects @ TL. Feb 27 was active during Sunday's avalanche shoot
Avalanche Summary
Highway avalanche control on Sunday produced avalanches up to sz 3.5 but most were in the size 2-2.5 range. One notable from the shoot was a 300+ m propagation on the East face of Mt Cheops. Monday a survey of the Connaught valley showed numerous sz 2's had run into the creek from Cheops Pk.
Confidence
Timing, track, or intensity of incoming weather system is uncertain
Problems
Wind Slabs
Wind Slab avalanches are the release of a cohesive layer of snow (a slab) formed by the wind. Wind typically transports snow from the upwind sides of terrain features and deposits snow on the downwind side. Wind slabs are often smooth and rounded and sometimes sound hollow, and can range from soft to hard. Wind slabs that form over a persistent weak layer (surface hoar, depth hoar, or near-surface facets) may be termed Persistent Slabs or may develop into Persistent Slabs.
Persistent Slabs
Persistent Slab avalanches are the release of a cohesive layer of snow (a slab) in the middle to upper snowpack, when the bond to an underlying persistent weak layer breaks. Persistent layers include: surface hoar, depth hoar, near-surface facets, or faceted snow. Persistent weak layers can continue to produce avalanches for days, weeks or even months, making them especially dangerous and tricky. As additional snow and wind events build a thicker slab on top of the persistent weak layer, this avalanche problem may develop into a Deep Persistent Slab.
