A few clouds build into the region in the afternoon. The current forecast shows that Monday night is the last good overnight refreeze until next weekend. Tuesday: Temperatures should already be near 2000 m at dawn and are forecasted to continue to climb to 3000 m by lunch time. Cloud cover increases to 50% as winds Light southeast winds are forecast for at all elevations Tuesday. Temps remain high through the night. Wednesday: Freezing level stays around 3000 all day.

Avalanche Summary
No avalanche activity reported Saturday or Sunday. On Friday in the Fernie area a skier triggered a size 1.5 avalanche with a 20 cm crown on an E facing slope at 2000 m Friday. Some loose snow activity on a SE facing slope was also reported, but, there is surprisingly little avalanche activity in the region currently.
Snowpack Summary
Mild temperatures in combination with the strong spring sun have helped to settle out the 20 cm from Wednesday's storm which came to rest on the April 4th melt/freeze crust. At this point last weeks storm snow has seen a lot of the sun & it has behaved quite well, producing very little in the way of avalanches. Recent storm snow has added up to 60-120 cm depending on the drainage. Our field team was out in the region Saturday; they were able to find the March 27th interface down around 90cm below the snow surface but test profiles did not produce any results on this layer. Large cornices loom over many lee slopes. Glide cracks are a concern, be sure to give them a wide berth as they are very sensitive and could fail at any moment.
