Avalanche Forecast

Poor - Due to the number of field observations

A warm front will move over the southern part of the province midday Wednesday resulting in mild temperatures and moderate to heavy precipitation. This will persist through Thursday before an Arctic front pushes down from the north on Friday. There is some uncertainty regarding freezing level extents and as a result the Northern Purcells may not see the warmer temperatures.Tues. Night/Wednesday: Precipitation 8-12mm, freezing levels starting at valley bottom rising to around 1500m late-Wednesday, ridgetop wind light-moderate SW-WWeds. Night: Precipitation 8-12mm, ridgetop wind moderate SWThursday: Precipitation 10-20mm, freezing levels rising as high as 2000m, possibly lower in the north, ridgetop wind strong SWFriday: A mix of sun and cloud, snow flurries possible, freezing level valley bottom, ridgetop wind light variable

Currently there are no recent avalanche reports. It's likely that there is enough snow at higher elevations for avalanches, particularly in wind loaded alpine features. Stay alert to changing conditions and signs of unstable snow like recent avalanches, significant loading by wind or snowfall, whumpfing or cracking, or rapid warming.

This is an estimate of what the snowpack may look like based of a few observations and previous weather. If you plan on riding in avalanche terrain be sure to supplement this with your own observations and please pass along any data you collect ([email protected]).Around 30-40 cm of recent storm snow has fallen in the past few days. This new snow may be sitting on a layer of surface hoar and/or a sun crust (similar to the South Columbia). Below this you will likely find a 15-25cm thick layer of sugary facets, which is sitting on a solid rain crust from early November. Recent strong and variable winds may have created dense wind slabs in exposed terrain. The average treeline snowpack depth is around 60-100cm. The snow probably tapers off pretty quickly as you drop below treeline. Watch out for exposed (or lightly buried) obstacles like stumps, rocks, logs, and open creeks.
