Avalanche Forecast

Moderate - Timing or intensity of solar radiation is uncertain

A high pressure ridge is re-establishing itself over most of BC bringing mostly sunny skies with a few cloudy periods. No precipitation is forecast for the next 4 or 5 days. Freezing levels may rise as high as 1500 metres during the day, then drop to valley bottom overnight. On Thursday the freezing level is forecast to rise to 3000 metres with clear skies.

Natural avalanche activity appears to have slowed down west of the divide. On the eastern slopes there were reports of  3 size 1.5 - 2  natural avalanches that occurred in the past 24 hrs. on NE aspects at 1900m. Most likely as a result of the wind loading that occurred during the last precipitation and wind event.

New snow with wind during the weekend contributed to wind slabs forming in lee terrain at treeline and in the alpine. A melt freeze crust which formed during the 2nd week of February has been reported between 40 and 70 cm., perhaps more deeply buried in the south of the region. This crust layer has also been reported with surface hoar in some places, for the most part on high and north facing terrain. Rain and warm temperatures at lower elevations created a 2 to 4cm rain crust, on south aspects below 1800 m. West of the divide, a layer of buried surface hoar might be found between 70 and 90cm below the surface. Recent reports suggest this layer has become less of a concern. As well, the stormy weather has encouraged new cornice growth. These cornices are reported to be huge and unsupported. With warm weather and sun in the afternoon, these could become a significant hazard.
