Avalanche Forecast

Synopsis: A strong upper ridge will build over the region on Monday and dominate through the week. This will bring mostly sunny skies, and moderate SW-W ridgetop winds. Freezing levels will rise to 1800 m on Monday and then climb steadily above 2000 m from Tuesday onward. No significant overnight freeze is expected.

Expect loose wet avalanches in steep terrain if it is raining or during sunny periods, especially if the sun or rain is affecting the fresh snow. Spring squalls may bring locally heavy precipitation and new storm or wind slabs may develop in higher terrain if you see significant new snow accumulation. Cornices collapses have been reported during periods of daytime warming. Occasionally these heavy triggers have caused large deep slab avalanches on the slopes below.

This is a broad general summary of conditions in the region based solely on recent weather data and previous snowpack information. It should be supplemented with local observations to help assess avalanche danger. Please refer to this document for additional snow and avalanche information and general travel advice. Over the last few days we have seen moderate amounts of moist or wet new snow mixed with showers or periods of rain below 1600-1800 m. Westerly winds have likely formed pockets of wind slab at higher elevations in lee of ridges and terrain features. The late January/early February persistent weak layer is deeply buried but could still wake up during periods of heavy precipitation (especially rain) or significant warming and solar radiation. Be particularly wary of this on large open alpine slopes. Cornices are large in some areas and should be given a wide berth.
