Lizard-Flathead

Cold dry weather will continue through the weekend. Avalanches are possible in alpine terrain where wind slabs have formed.

FRIDAY Night: Mainly clear, light east wind, alpine high temperature -12 C.

SATURDAY: Sunny, light southwest wind, alpine high temperature -10 C.

SUNDAY: Mostly sunny, Light west wind, alpine high temperature -8 C.

MONDAY: Mainly cloudy, light southwest wind, alpine high temperature -6 C.

With little to speak of in terms of recent snowfall, the main concern right now is old wind slabs in open terrain. Last weekend several small human triggered wind slabs were reported around the Harvey Pass area. Cold windy weather over the past few days has potentially formed more thin wind slabs in this type of terrain. Concern is reduced in areas where the snow depths have not yet reach the threshold for avalanches.

The Lizard Flathead region unfortunately missed out on a recent storm that hit Alberta. Little to no snow fell in the Lizard Range while eastern parts of the region received 5-15 cm of snow. This leaves the region with an overall thin snowpack, with somewhere between 50 to 100 cm of snow in the alpine (see the photo in this recent MIN report from Harvey Pass for an idea of current coverage).

Two crusts have been reported in the middle of the snowpack. There is some uncertainty about how well the snow is bonding to these crusts. Although they are probably unreactive right now, be prepared to back off to mellow terrain if you encounter signs of instability such as whumpfs or shooting cracks, which could indicate these layers are in fact reactive.
