Avalanche Forecast
Regions: Waterton Lakes.
Cooler temps for the next couple days = all about timing. Expect firm snow in the morning and corn in the afternoon.
Snow is disappearing quickly in the park, south facing ice climbs have fallen down. Come get that last bits of winter while it lasts.
Weather Forecast
Tues Cloudy in the AM with flurries, clearing near noon. Alpine high near zero with M-N winds. FL 1800m
Wed: Clear skies with an alpine high +1. Winds S-SW and FL 1800m
Thurs: Cloudy with flurries and an alpine high of -1. Winds L-M SW and FL 1600m
Snowpack Summary
Moist surface snow on all aspects to 1800m, higher on solar slopes. Above 1800m a rain crust exists on all aspects well into into ALP. A series of crusts and windslab make up the midpack. Lower snowpack is well settled 1F to P. HS 250-300 cm near the continental divide.
Avalanche Summary
Several new natural wet loose avalanches to size 2 were observed on Monday. One notable slab avalanche from a thin rocky start zone, initiated at peak solar and entrained wet loose to size 3. Please report any observations to the Mountain Information Network.
Confidence
Timing or intensity of solar radiation is uncertain
Avalanche Problems
Loose Wet
Wet loose activity will increase with day time warming. Pay close attention to steep rocky solar slopes.
- Minimize exposure to steep, sun exposed slopes when the solar radiation is strong.
Aspects: East, South East, South, South West, West.
Elevations: All elevations.
Likelihood: Likely
Expected Size: 1 - 3
Cornices
Sustained high FL this week is weakening cornices. A cornice drop can be hazardous on its own, or also has the potential to trigger larger avalanches.
- Cornices become weak with daytime heating.
- Give cornices a wide berth when travelling on or below ridges.
Aspects: North, North East, East, South East, North West.
Elevations: Alpine, Treeline.
Likelihood: Possible
Expected Size: 1 - 3
