Avalanche Forecast
Regions: Waterton Lakes.
Weather Forecast
Temperatures rose sharply Saturday night, but should cool slightly to hover around -5 at Treeline the next few days. Expect variable cloudiness, with occasional light snowfall, but nothing significant until Tuesday night, when we could see 5-10cm of new snow. Winds Strong from the SW on Sunday night and Tuesday night, otherwise Moderate.
Snowpack Summary
25cm of recent snowfall has made for good skiing below treeline, and sluffing in steep terrain. Strong SW winds are blowing this around to form Wind slabs in lee areas, and warm temperatures may be turning unconsolidated recent snow into storm slabs. These sit on a weak layer of Facets and Surface Hoar, or sun crust, down 25-50cm.
Avalanche Summary
Several Size 1 Loose Dry avalanches were artificially triggered by parks forecasters in steep trees near Cameron Lake on Friday, and numerous natural Size 1 Loose Dry avalanches were observed today from steep terrain at all elevations. One natural Size 1.5 Wind Slab was observed today in alpine terrain, triggered by sluffing from cliffs above.
Confidence
Due to the number of field observations
