Avalanche Forecast
Regions: Jasper.
Weather Forecast
Arctic air will dominate with few clouds, light winds, highs near -10 and lows near -20C. Warm, wet, pacific air is forecast to over-ride the arctic air Wednesday morning. This system may bring up to 25mm of precip with moderate winds and temperatures nearing -5C.
Snowpack Summary
15 cm of new snow arrived last weekend with light N winds. This sits over previous wind slabs formed by 40cm of snow pushed around mainly by strong SW winds. Mid-pack persistent weak layers, mainly preserved Jan 7 surface hoar down 40 to 60cm and the rotten Dec 15 facets sitting just below are still a concern but remain stubborn to triggering.
