Waterton Lakes National Park Avalanche Forecast
Mar 9th, 2012 8:18PM
Heat and wind have triggered some small slides that have pulled out deeper persistent slabs. Continued warm temps, strong winds, and a bit of snow are in the forecast. Carefully consider the effects of these factors above you and under your skis.
Previous wind slabs are now buried 15cm and still could be triggered by skiers. NW winds forecast for Wed will be building windslabs outside of normal locations. With all the new snow from the weekend, these slabs will grow quickly.
Aspects:North, North East, East, South East, South.
Suncrusts and Surface Hoar now down 50 to 100 cm. Watch daytime heating on solar slopes above the crusts. Isolated areas on Northerly slopes protected from the sun and wind may hold surface hoar. If triggered these slabs would be large.
Aspects:North, North East, East, South East, South, South West.
The recent storm snow is settling with the effects of wind and heating forming a stiffer slab. These shallow slabs are weakened with daytime heat and will be sensitive to light loads: skiers, snow rolling off of rocks and trees or moist sloughs.
