Kootenay Boundary

The storm should offer one last pulse of snow and wind Tuesday night before it exits to the east. Both surface hoar and crust are just under the new snow, so conservative terrain selection remains prudent as the snowpack adjusts to this new load.

Low - Due to the number of field observations

The system that has brought significant rain in the valley bottoms and upwards of 30 cm of snow to the Boundary region should offer one last pulse Tuesday night. Wednesday marks the start of what looks to be a pretty significant drying trend as cold air begins to descend from the Arctic. No significant precipitation is expected for the forecast period and it looks like there is potential for clear skies by Sunday.TUESDAY NIGHT: Freezing level around 1000 m, moderate to strong west/southwest wind, 1 to 5 cm of snow possible with light rain in the valley bottoms.WEDNESDAY: Overcast, freezing level holding around 1400 m, light to moderate southwest wind, trace of precipitation possible.THURSDAY: Scattered cloud cover, freezing level around 1000 m, light variable wind, no significant precipitation expected.FRIDAY: Scattered cloud cover, freezing level beginning near valley bottom rising to 1000 m, light variable wind, no significant precipitation expected.

A MIN report from Saturday describes a snowboarder triggering and getting caught in a smaller (size 1) storm slab that appeared to have been formed by cross-loading winds in the Ymir bowl area. See the full report on the MIN here.On Saturday in the Meadow Creek area of the neighbouring South Columbias, a group of snowmobilers triggered a large deep persistent slab that released to ground and resulted in multiple involvements. Although still an isolated event, travelers should be aware of roughly similar snowpack characteristics in the Kootenay Boundary region and maintain cautious travel practices - especially in complex terrain at higher elevations. See the full report on the MIN here.Please submit any observations you have to the Mountain Information Network here.

Alpine snow depths in the region are around 70 to 90 cm. 10 to 40cm of recent snow overlies a layer of surface hoar that was buried on November 21. This layer is expected to be variable in nature and may be sitting on a crust in some locations. On solar aspects it may have been melted into a crust.
