Avalanche Forecast

Poor - Timing, track, or intensity of incoming weather is uncertain

A low pressure center sitting SW of Montana will continue to move SE, this should be arriving in Southern Alberta by Thursday afternoon. Depending on timing and track, this low may spread moderate amounts of precipitation to the BC interior Wednesday night into Thursday. Ridgetop winds will start light-moderate from the South, switching moderate SW through Thursday. Freezing levels will fall to 1800 m. Some lingering flurries may exist into Friday with freezing levels near 1500 m. The weekend will see a fairly inactive ridge of high pressure dominating the interior, bringing sunny skies and freezing levels up to2500 m. Confidence is poor for Thursday/Friday due to the uncertainty of the lows location in Alberta. This could potentially bring more than anticipated (moderate) precipitation amounts to the regions.

Loose snow activity on a SE facing slopes have occurred. Most of this consists of pinwheeling, and point release avalanches involving the surface snow, no slabs.

Spring like warm weather has promoted settlement and bonding within the snowpack. Melt-freeze conditions are existing with moist snow below 1700 m on all aspects, and to ridgetop on solar aspects. Below the surface, down 60-120 cm sits on the March 27th interface. Our field team was out in the region last Saturday; they were able to find the March 27th interface down around 90cm but test profiles did not produce any results on this layer. They were also out on Tuesday, found the layer again which seems to be more prominent on southerly aspects where the crust is thicker. The upper snowpack seems to be bonding to this interface and may soon become dormant. Glide cracks are a concern with the forecast rain below 1500 m. Be sure to give them a wide berth as they are very sensitive and could fail at any moment.
