Avalanche Forecast
Regions: Waterton Lakes.
Weather Forecast
Flurries/showers can be expected Friday with Moderate to Strong West winds and freezing levels reaching 2100m. More Sustained flurries with light winds shifting to the N Saturday will only allow freezing levels to reach 1600m. With more sun expected Sunday freezing levels will return to 1900m although winds will stay unchanged.
Snowpack Summary
Strong solar heating has created moist snow on all but North aspects above treeline and solar inputs have allowed for only superficial freezing in the last few days at low elevations. Moderate to strong West winds continue to transport modest amounts of snow and have created thin and spotty slabs on E and N aspects TL and ALP.
Avalanche Summary
Daily loose moist activity on all aspects below treeline and to mountain tops on sun exposed aspects has been seen over the last few days. Minimal cooling overnight has kept solar slopes sensitive to daily solar inputs. This activity should diminish with the cooling expected Saturday however solar heating on Sunday will allow the pattern to resume
Confidence
Timing or intensity of solar radiation is uncertain
