Avalanche Forecast
Regions: Waterton Lakes.
Weather Forecast
Continued precip through Friday with the freezing level dropping to about 1800m. Winds will pick up to strong. Clearing Friday night should allow for a light freeze but Saturday will bring sunny skies and a 3000m freezing level. A poor recovery is likely into Sunday with clouds and some light precip forecast.

Snowpack Summary
10 to 20 cm of snow now lies on the April 11 crust that is found on N aspects to 2300m and to ridgelines on solar aspects. This is becoming soaked by rain as of late Thursday evening. The deeply buried February Facets and early season Basal Facets remain weak and will likely wake up with significant and sustained heating.
Avalanche Summary
Widespread Loose Wet activity is occurring as the falling rain soaks the fresh snow. These events have been up to size 1.5 running 10 to 15 cm deep over the April 11 crust on all aspects below about 2200m.
